INTRODUCTION

The SK-ACPE Advanced Control Panel is a highly sophisticated, yet simple to use, two door access control unit with built-in Ethernet communications. The unit accepts readers of almost any technology, with a Wiegand output up to 40 bits, including Proximity, Touch Card, Wiegand, Magnetic Stripe, Bar Code, Optical, and Biometric. Each of the two passageways controlled by the unit is completely independent of the other and is configured, programmed and viewed separately.

Up to 100 SK-ACPE Panels may be linked together on a twisted pair (plus signal ground) RS-485 bus. When used with SK-NET™ software, a highly featured, easy to use, distributed intelligence access control system can be created.

Each of the two passageways controlled by the SK-ACPE has two programmable inputs which may be programmed by the user to function as a Door Monitor, Tamper Monitor, Remote Open, Remote Inactive, Bell, Arming Circuit, or User Defined Input.

Each of the two passageways controlled by the SK-ACPE has two outputs. One output is the "Latch Relay," which operates the door locking or operating device. The other "Auxiliary Output" is programmable by the user to activate under one of several possible alarm or special conditions.

SK-ACPE will control access for up to 65,535 individuals in 15 weekly time schedules (Time Zones) independently for each of the two passageways. Time Zones include a holiday schedule that is followed when one of the 32 user programmable holidays occur.

Any Access Card may be designated as a "Limited Use" card, and its use may be restricted to allow access for a given number of days or weeks or for a given number of times.

The SK-ACPE may be programmed with a PC. Transaction information is stored by the unit and may be downloaded to a PC, or serial printer. Up to 10,000 transactions are stored.

Since the SK-ACPE has nonvolatile memory, reprogramming after a power loss is unnecessary.

CARD ID NUMBERS AND FACILITY CODES

Access cards used with the SK-ACPE have two encoded numbers: the ID number which is different on each card, and the Facility Code, (also called a system or site code) which is normally the same for all cards at a given site. When a card is read, the system first verifies the Facility Code, then it checks the ID Number against its internal "card list" in memory to see if the card is void or valid. It also checks the Time Zone, the card's Antipassback status, and the Limited Use count.

SETTING THE FACILITY (SYSTEM) CODE

IMPORTANT

Before programming or using a new unit, the correct Facility Code must be set.

When power is first applied, or when the reset button is pushed (see Figure 3) the LED on each of the two readers will flash red and green alternately. While the LED is flashing, present an Access Card with the proper facility code to one of the readers and remove it (note LED turns solid green for about 1 second and the beeper beeps to indicate that the card has been read). The SK-ACPE will "remember" the facility code and retain it until reprogrammed. It is not necessary to present the access card to the second reader since it is automatically set for both passageways. After setting the facility code, wait for the LED to stop flashing before attempting to use the reader.

To change a facility code (or to set the facility code if the LED is not flashing red/green), momentarily depress the reset button. The LED indicator will flash red and green alternately. If the reset button is pushed, but no card is presented to the reader before the LED indicator times out, the facility code will be unchanged.

In some cases it may be necessary for the unit to recognize more than one facility code. Typical instances are when it is necessary to read cards that work in two independent locations that already have different facility codes or when two different reader technologies are used in the same system, each of which has a different facility code.

The SK-ACPE can be set to recognize up to sixteen different facility codes. To program multiple facility codes, follow the procedure above for programming a single facility code, but present a card with the second facility code (and additional facility codes if necessary) to the reader before the red/green LED indicator times out.

Note that it is not generally recommended to combine sets of cards with different facility codes, because the unit cannot distinguish between access cards having different facility codes and the same ID number. It is also important to distinguish between ID numbers and the facility code when programming. See Figure 1 for examples of the numbering location.

For example, if you have two sets of cards numbered 1-100, with facility codes 12345 and 23456, and you delete cards 1 - 10 from the reader's internal "card list," then cards 1 - 10 with either facility code will be denied entry at the reader.

INSTALLATION

CAUTION SHOULD BE TAKEN NOT TO TOUCH CIRCUIT BOARD OR ELECTRONIC COMPONENTS PRIOR TO AND DURING INSTALLATION TO AVOID ELECTRO-STATIC DISCHARGE (ESD) DAMAGE.

Installing the SK-ACPE

• 1. Select a location for the SK-ACPE unit that is secure and sheltered from weather and extreme humidity. Choose a location that facilitates access to power and is reasonably close to the doors that are to be controlled (no further than 500 feet).
• 2. Using the unit as a template, mark on the mounting surface the location of the four mounting holes.
• 3. Install appropriate mounting hardware (anchors, retainers, etc.) to the mounting surface if necessary.
• 4. Screw #6 or #8 mounting screws into the top 2 mounting holes of the mounting surface, leaving about 1/4" clearance.
• 5. Place panel top key-way mounting holes over installed mounting screws and slide panel down.
• 6. Tighten top mounting screws.
• 7. Install two bottom mounting screws (see figure 2).
• 8. Route cables into the enclosure through knockouts in sides or back of box, being careful not to nick or scrape insulation on any rough edges.

figure 2

Wiring

The SK-ACPE unit is organized so that the wiring for door #1 is on the right side of the panel and the wiring for door #2 is on the left side of the panel (see figure 3).

For ease of installation and servicing, plug-in terminal blocks are provided.

figure 3

POWER & BATTERIES

The SK-ACPE unit must be connected to a source of low voltage power. The SK-ACPE should NOT be connected to the same power supply that is providing power to an electric lock or strike. To power the SK-ACPE, you must use a power supply, which is properly rated for the panel, plus any connected equipment:

SK-ACPE with RK-WM / RK-WS readers 24VDC, 500 mA or 16.5VAC 40VA transformer SK-ACPE with SK-WLSE-MOD 24VDC, 500 mA or 16.5VAC 40VA transformer Add RK-WL readers to either of the above 16.5VAC 40VA transformer

The basic configuration can be powered by the SK-ACP-PS, which includes a 24VDC 1A supply and a 4AH backup battery, or by a 16.5VAC 40VA transformer (SK-XFRMR)

Terminals 7 & 8 on plug "J7" must be connected to 16.5 to 24 volts, AC or DC. You may also connect the SK-ACPE to 12 VDC, but in this case you must connect your power supply to the red (+) and black (-) wire leads on the lower left corner of the panel instead of the "J7" plug. If you use 12 VDC you cannot install a standby battery in the SK-ACPE.

When 16.5 – 24 volts is used to power the SK-ACPE, you may connect the red and black wires to a 12 volt standby battery. Polarity (+/-) must be observed. The, 10" X 11" SK-ACPE-LE can accommodate batteries up to 4.0 Amp-hours

Do not energize the SK-ACPE until all other connections are made.

READERS

SK-ACPE is designed to accept any reader or keypad with a standard Wiegand interface. The reader for door #1 is connected to plug "J5", the reader for door #2 is connected to plug "J6". (See figure 3) SUGGESTED CABLE IS Alpha 1296C. The SK-ACPE will provide up to 400mA to power each reader. If the readers you use require more current, an external power supply must be used.

INPUTS

Each reader may be associated with up to two auxiliary inputs. Inputs might include remote switches, door contact sensors, vehicle presence detectors, etc. If you connect inputs to the SK-ACPE you must define those inputs using SK-NET™ software (see SK-NET™ manual). Note that input 1 (#7) and input 2 (#9) share a common terminal (#8) on plugs "J1" and "J2". All inputs are configured as normally open circuits. However, in many cases a "Door Monitor" input should be a normally closed circuit. To convert any input defined as "Door Monitor" to normally closed, you must reconfigure the inputs as Normally Closed, using the SK-NET™ software (see SK-NET Manual.) For testing and troubleshooting purposes, LED indicators are located on the circuit board near the input terminals, just below the LED Indicator for the Latch Relay (Figure 4). The LED lights when the input is in the alarm (off-normal) state.

CHASSIS GROUND

The SK-ACPE has a chassis ground terminal at the bottom of the PCBA just to the left of J8. This terminal must be connected to a good, reliable Earth ground, to enable the on-board gas tube surge suppressors to work effectively. If this is not done, damage to the controller may result. A crimptype wire lug is supplied with the unit. Secure the lug to the terminal using the provided screw. Crimp the ground wire to 10AWG stranded, insulated wire, and connect the wire to the closest Earth ground available, such as a 10-ft buried copper grounding stake, Building Electrical Ground, or a steel cold water pipe, which must be contiguous, with no PVC or ABS sections.

OUTPUTS

Each door controlled by the SK-ACPE has two double pole, double throw relays associated with it. The "latch relays" are located on "J1" and "J2", terminals 1-6. The "auxiliary relays" are located on "J3" and "J4". One pole of the latch relay is typically used to open or close a circuit to unlock a door or activate a gate operator. The other pole of the latch relay operates simultaneously and may be used to shunt an alarm contact, start a video recorder, etc. The auxiliary relay may operate according to a variety of user-defined conditions. These must be programmed using SK-NET™ software (see SK-NET™ manual). NOTE: Two MOVs (metaloxide varistors) are provided with each SK-ACPE. These must be installed between the "Common" and either the "Normally Open" or the "Normally Closed" terminals where power to the electric lock or strike is being switched (See Figures 7 and 8). For testing and troubleshooting purposes, an LED indicator is located on the circuit board adjacent to each relay. The LED lights when the relay is activated.

COMMUNICATIONS JUMPER

The jumper on pins 2 and 3 of Jumper connector JP1 must be installed to enable RS-232 communications at Jack J11 and J7. If the SK-WLSE-MOD Wireless network module is installed at J12, this jumper must be moved to pins 1 and 2 of JP1 to enable RS-232 communications with the wireless module.

LED INDICATORS

The SK-ACPE features 12 LED indicators, which will assist the installer when connecting, testing and troubleshooting the readers, inputs and outputs, power and communications wiring. These indicators and their functions are described in Figure 4.

RS-232

You may connect RS-232 communications to the SK-ACPE either by using plug "J7", terminals 1-5, or by plugging the RS-232E cable into the J11 jack at the lower right hand side of the circuit board (See figure 3). Note that jumper J1 must be installed on pins 2 and 3 to enable RS-232 communications at J7 and J11. RS-232 requires at least 5-conductor cable. SUGGESTED CABLE IS Belden 9535. RS-232 is used to connect the COM port of a PC to a single SK-ACPE, or as a gateway to a network of SK-ACPEs. (COM ports are typically DB9 male or DB25 male jacks on the back of a personal computer.) Newer computers may not have COM ports, in which case, you must purchase the SK-USB USB-to-serial converter, which plugs into a USB port on your computer and provides a DB-9 connector, which can be connected to the SK-ACPE-LE by using an SK-PLUG9 pigtail, extending the cable as long as needed, using Belden 9535 or equivalent cable. When connecting a PC via RS-232 the distance from the panel to the computer should not exceed 100'. (For longer distances, see "RS-485" below.) A serial printer may also be connected to the RS-232 port of any SK-ACPE. This will allow all system transactions to be printed as they occur. (A printer may be connected to one SK-ACPE even if a computer is connected to another SK-ACPE in the same network. The SK-ACPE must be configured for Serial Printer operation-See Appendix D.) An external modem might also be connected to the RS-232 port of an SK-ACPE for dial-up applications using SK-NET-MLD software. While any Hayes compatible 56K modem may be used, we highly recommend that you use the Secura Key SK-MDM. The SK-ACPE contains the configuration data, or "setup string" which allows this modem to be configured in the field without the use of a computer and without setting DIP switches. (See Appendix C for modem instructions.) Figure 5 shows the RS-232 pin connections for a PC, printer, or modem.

TAMPER SWITCH

The SK-ACPE includes an input for an enclosure Tamper Switch, and it also has an onboard beeper, which can provide an audible warning if the SK-ACPE enclosure is opened. The SK-ACPE is provided with a jumper wire across J7, inputs 1 & 6, which should be removed if the tamper switch will be used. The Tamper Switch is available as an accessory, SK-TS-CP, which can be fastened to the enclosure with three screws (included) and wired to J7, inputs 1 & 6. To stop the beeper from sounding during maintenance by authorized technicians, the tamper switch can be held down for about 20 seconds, and the beeping will stop (this will be reset again after the panel is closed.)

Installation of Metal Oxide Varistor with Electric Strike

Install the enclosed 40-volt MOV (Metal Oxide Varistor) across the relay contacts in the access control unit, as shown. The Access Control Unit must have its own power supply.

FIGURE 7

Installation of Metal Oxide Varistor with Magnetic Lock

Install the enclosed 40-volt MOV (Metal Oxide Varistor) across the relay contacts in the access control unit, as shown. The Access Control Unit must have its own power supply.

FIGURE 8

RS-485

The RS-485 bus (Connector J8) is used to link multiple SK-ACPE units into a network. Where two or more SK-ACPEs are linked, you must run cable between the "J8" plugs on each panel. Terminals 1 & 2 must be a twisted pair of wires. SUGGESTED CABLE is Belden 1585A (CAT-5e). Terminal 3 is a "signal ground", which should be connected to one conductor of another twisted pair. This must be an insulated conductor and it should NOT be connected to earth ground.

Where the distance from the PC to any one of the SK-ACPE units is greater than 100', you may install an RS-232 to RS-485 converter (Secura Key p/n NET-CONV-P) to the COM port of the computer. If your PC does not have a COM port you will need to purchase a USB-to-serial converter (SK-USB), and then connect the RS-485 converter to the USB converter. From the converter you then run RS-485 cable and connect SK-ACPEs anywhere along the RS-485 bus. The total RS-485 cable distance, including the distance between all SK-ACPEs, may be up to 4000'.

Figure 9 shows how each SK-ACPE is connected to the RS-485 bus.

Earth Grounded Shield is highly recommended in environments subject to high voltage electrical discharge (i.e. lightning). Shield should be connected to earth ground only at one end of the cable. DC Signal ground is required. DC Ground wire is NOT to be connected to earth ground.

FIGURE 9

ETHERNET

The RJ45 Ethernet connector, located on the lower right-hand corner of the circuit board, is used to link individual SK-ACPE panels to a Local Area Network. You can use CAT 5e or CAT6 cable terminated with RJ45 jacks to connect each panel to a router, hub, or switch located up to 300 feet away. See Appendix D for information on how to configure the SK-ACPE for use on a LAN.

PROGRAMMING THE SK-ACPE WITH SK-NET™

The SK-ACPE must be programmed with SK-NET™ software. Please refer to the SK-NET™ manual for programming instructions. (The SK-NET™ manual is available at www.securakey.com)

READERS AND CARDS

USING SK-ACPE WITH SECURA KEY PROXIMITY READERS AND CARDS

Secura Key offers proximity and contactless smart card readers in a variety of sizes for use with the SK-ACPE panel. Secura Key readers read Secura Key cards only, except for the SK-RKDT readers, which read both Secura Key and most HID Proximity cards with non-proprietary pass-through formats, such as H10203 (26-bit) or HN10001 (Northern 34-bit). Secura Key cards have two encoded numbers: the ID Number which is different on each card, and the Facility Code (also called a system or site code) which is normally the same for all cards at a given site. When a card is read, the system first verifies the Facility Code, then it checks the ID Number against its internal "card list" to see if the card is void or valid. It also checks the card's Antipassback Status, Time Zone and Limited Use count.

USING SK-ACPE WITH NON-SECURA KEY CARDS AND READERS

SK-ACPE will accept data from any reader with an SIA Wiegand interface. When using non-Secura Key readers and devices, SIA 26-bit Wiegand format will present the least problems. Formats with ID fields longer than 16 bits will not work properly with the SK-ACPE. Custom formats are setup using the SK-NET™ software (see the SK-NET software manual.) Contact Secura Key technical support with questions about custom format compatibility with SK-ACPE.

ORDERING ADDITIONAL CARDS FOR YOUR SYSTEM

The SK-ACPE can learn up to 16 different facility codes, but it is not generally recommended that you combine sets of cards with different Facility Codes in the same system. The SK-ACPE cannot distinguish between cards which have different Facility Codes and the same ID Number. For example, if you have a card with Facility Code A1 and ID Number 15 and you have a card with Facility Code B2 and ID Number 15, and the SK-ACPE has been programmed to accept both Facility Codes, it will see these as the same card.

When ordering additional cards it is recommended that you place a factory order specifying the existing Facility Code and beginning with the ID Number which is one higher than the highest card already in use.

SETTING THE FACILITY CODE

When power is first applied to the SK-ACPE the LED on each of the connected readers will flash alternately Red and Green. While the LED is flashing, hold an Access Card with the correct Facility Code near a reader for about one second. The LED should show a long Green flash and the reader will beep. If an additional Facility Code is to be entered, present an Access Card with that Facility Code in the same manner. Repeat for each Facility Code to be entered. Let the LED stop flashing Red/Green before attempting to use an Access Card.

To change a Facility Code (or to set a Facility Code if the LED is not flashing Red/Green) momentarily depress the reset button on the SK-ACPE. Depressing the reset button will NOT erase memory or disrupt other programming.

To add an additional Facility Code to a system, while retaining the existing Facility Code, you must depress the reset button and then present a card with each Facility Code to the readers while the Red/Green flashing is occurring. If you only present a card with the "new" Facility Code the system will "forget" the old Facility Code. It is only necessary to present an Access Card to one of the two readers connected to each SK-ACPE in the system.

CONNECTING AN SK-ACPE TO A LOCAL AREA NETWORK

The SK-ACPE-LE control panel features a built-in Ethernet connection. The panel may be connected directly to a hub, switch or router on your Local Area Network up to 300 feet away.

Alternately, you can use either the SK-WLSE-MOD Wireless Network Module (which connects with an 802.11 wireless network.) This unit plugs into connector J12 on the SK-ACPE, and it receives its power from the panel. You must move the 2-pin jumper at J1 to pins 1 and 2 before installing the module.

Refer to the Install/Setup documentation provided with the SK-WLSE-MOD for details on connections, IP addressing, setup and testing your network connection.

To configure your system using SK-NET-MLD software, see SK-NET™ Manual for instructions.

NOTES:

• 1) Always close SK-NET™ before closing WINDOWS® to avoid LAN communications failures.
• 2) The manufacturer's instruction manual is included with the SK-WLSE-MOD. Keep this document for additional troubleshooting and setup information.

Configuring IP Addresses in the SK-ACPE

Information you will need

The SK-ACPE now has built-in Ethernet adapter which must be pre-configured with various IP addresses before connection to the LAN. Panels connected via RS232 or RS485 do not need to be configured with IP addresses.

Before starting the setup procedure, contact your IT Manager or Network System Administrator for the following required information:

TCP/IP Address (one for each panel connected with TCP/IP)

Subnet Mask

Default Gateway

DNS Server

Each address will consist of four groups of 3-digit numbers separated by periods (e.g. 111.222.333.444)

Hardware Connection

You must connect a Windows computer COM port to the J11 port on each SK-ACPE, using the RS-232E cable (or to J7 using a wire pigtail, see Figure 3). If your computer does not have a serial COM port, purchase and install the SK-USB USB-to-Serial Converter on your computer, and connect the DB9M connector on the converter to the DB9F connector on the RS-232E cable.

1.6 Using RS-232 Voltage Measurements to Check Communication Problems

If you cannot connect, it will be necessary to take voltage measurements to identify whether the problem is with the SK-ACPE or with the computer.

RS-232 Direct Connection

• 1. From the Explorer screen, right-click on the Location.
• 2. Select Properties.
• 3. Click on the Connection tab.
• 4. Uncheck the box next to "Gateway (RS-232)"
• 5. Click on the Connect button.

The system will fail to connect, but in the process it will open the computer COM port, making a voltage test possible.

• 1. Voltages: Measure voltages at the gateway reader's terminal block, communications pins 1 to 5. Connect the ground lead to pin 1 (logic ground) for all measurements.
  • a) Pin 2 (Receive Data, RXD). The voltage should read between -5 VDC to -12 VDC. This voltage comes from the PC. If the voltage is wrong or missing, disconnect the reader from the PC, and measure the voltages at the reader (should be 0.0 VDC) and at the PC (should be between -5 VDC to -12 VDC).
  • b) Pin 3 (Clear to Send, CTS). The voltage should read between +5 VDC to +12 VDC. This voltage comes from the PC. If the voltage is wrong or missing, disconnect the reader from the PC, and measure the voltages at the reader (should be 0.0 VDC) and at the PC (should be between +5 VDC to +12 VDC).
  • c) Pin 4 (Request to Send, RTS). The voltage should read between -5 VDC to -12 VDC. This voltage comes from the Card Reader. If the voltage is wrong or missing, disconnect the reader from the PC, and measure the voltages at the reader (should be -9.5 VDC) and at the PC (should be 0.0 VDC).
  • d) Pin 5 (Transmit Data, TXD). The voltage should read between -5 VDC to -12 VDC. This voltage comes from the Card Reader. If the voltage is wrong or missing, disconnect the reader from the PC, and measure the voltages at the reader (should be -9.5 VDC) and at the PC (should be 0.0 VDC).

After testing voltages, return to the Location/Properties/Connection box and re-check the box next to "Gateway (RS-232)".

1.7 NET-CONV Converter Connection

If you cannot connect and you are connected using the NET-CONV converter, test voltages as follows:

• 1. Measure input voltage from the converter power supply. It should be between 9 VDC and 16 VDC.
• 2. Measure voltage between Ground (minus side of power supply) and TD (A). It should be 0 VDC.
• 3. Measure voltage between Ground (minus side of power supply) and TD (B). It should be between 2.5 VDC and 5 VDC.

If these voltages are incorrect, contact Secura Key Technical Support.

1.8 Power Reset

Occasionally it may become necessary to perform a power reset on a SK-ACPE panel (for example, after a power surge.) The SK-ACPE has a multi-level power reset procedure, with options depending on how long you hold down the reset button following restoration of power. The Unit will beep, indicating the level of reset which has occurred.

To perform a Power Reset:

• 1. Disconnect power from the reader or panel (including any backup battery)
• 2. Hold down the reset button.
• 3. While holding the reset button, restore power, and continue holding the button until the unit beeps and the desired reset level occurs:
  • One (1) beep will default the Baud rate to 38400 for the gateway (RS232), and (RS 485 communications), exit the printer mode, reset password to 12345, and resend the wireless settings if being used.
  • Two (2) beeps (3 seconds later) will change the node ID's. This procedure will reset the node address, requiring a recovery procedure in SK-NET™ (see below).
  • Three (3) beeps (15 seconds later) will perform a factory default for the panel.

Recovery Procedure:

To clone the readers:

• 1. From the Explorer screen, right click on the Location Name.
• 2. Select New.
• 3. Select Readers.
• 4. Select Quick Find (with less than 20 readers), or Search if (with more than 20 readers).
• 5. SK-NET™ will find the original reader(s) as new ones.
• 6. Click OK to bring them into the system. Do not log in at this time.
• 7. Look under All Readers and you will notice that you now have duplicate reader(s) names. The old one will still have the red X through the icon, and the new one will not.
• 8. Drag and drop the New reader(s) on to the old reader(s) with the same name. You will be asked to Replace the reader, click Yes. This will clone the original reader settings in to the New reader.
• 9. Right click on All Readers and select Login. Now all the readers should have a green check next to each reader.

1.9 Replacing an SK-ACPE

When replacing or adding an SK-ACPE to a system, it is recommended to perform a "2-beep" power reset (See Sec. 1.8).

NOTE: There are no changes required in SK-NET™ when replacing a card reader connected to the SK-ACPE

While replacing the SK-ACPE it is recommended that you note the serial number of the board being replaced along with the new board being used for the replacement. This will simplify the following steps used in this procedure.

Note: DO NOT delete any readers from the Explorer screen!

After completing the replacement of the board you need to start SK-NET™, connect and login. Click on the + next to All Readers and you will notice a red X through the reader(s) icon(s) which have been replaced.

• 1. Left click on All Readers, now it will be highlighted.

• 7. After SK-NET™ finds the new readers, click OK to add them to the system (note that under All Readers the new readers found show the serial number as the name of the reader). Do not login.
• 8. Look at the serial number or name of the new reader(s) and drag and drop the new one over the old one with the red X through the icon (be sure to include the "–1" or "–2" as part of the serial number).
• 9. When asked 'Do you wish to replace the reader?' Answer YES. SK-NET™ now will use the data files from the old reader and program them in to the new reader including sending cards.
• 10. Repeat steps 8 and 9 for all readers being replaced.
• 11. Test a card or two, the replacement is now complete.

APPENDIX F

PREVENTING LIGHTNING DAMAGE

SURGE PROTECTION FOR ACCESS CONTROL SYSTEMS

Access Control equipment is susceptible to damage from lightning, especially when installed outdoors. Voltage spikes which travel through buried data cables, telephone lines or AC power lines can damage Access Control equipment indoors, as well.

The SK-ACPE-LE is equipped with Gas Discharge Tube Surge Arrestors on the RS-485 communications lines (J8). For these devices to work properly, the SK-ACPE chassis ground (located on the circuit board, just to the left of J8) must be connected to a good Earth Ground such as a 10' Copper Ground Stake (best) or AC Power Ground.

While nothing can protect equipment from a direct lightning hit, surge protectors can help to minimize the damage caused by nearby lightning strikes. Surge protectors operate by connecting Transorbs or Varistors from data lines to ground. Surge protectors have no effect on normal circuit voltages, but can act quickly to divert large voltage spikes to ground and away from sensitive components.

Although Secura Key equipment includes on-board surge suppression, properly grounded off-board devices will provide the best protection.

Where to Install Surge Protection

• On the AC line voltage input to the PC. (A UPS with surge protection is recommended).
• On the AC line voltage input to any transformer or DC Power Supply connected to an SK-ACPE or Modem.
• On RS-485 data lines connecting an SK-ACPE to a PC, or to other SK-ACPE's.
• On the power supply of a NET-CONV-P RS485 Converter (if used).
• On RS-232 data lines from SK-ACPEs to PCs, Printers or Modems.
• On Telephone lines connected to Modems.
• On Data lines connecting card readers or keypads to the SK-ACPEs.

Surge Protectors

There are many manufacturers of surge protectors. Some are designed to protect a single type of circuit such as high voltage AC, low voltage DC or telephone lines. Secura Key offers two multifunction surge suppressors that are well-suited to protecting access control equipment. The DTK-XR is a good choice for protecting an SK-ACPE panel from power, data and telephone line surges. If the card readers or keypads attached to the SK-ACPE are located outdoors you may also wish to install DTK-CR protectors on each reader circuit. Wiring instructions for these surge protectors appears on pages F4 and F5.

Protect Both Ends of Data Lines

Surge Protectors should be installed at both ends of all Data Lines.

Wire Distance from the Surge Protector

You must locate the protector at least three wire feet away from the device being protected. The additional wire resistance will dissipate the energy from leading edge of the spike. The wire can be coiled; a three-foot physical distance is not required.

Grounding the Surge Protector

Surge protectors must be connected to a verified good, nearby earth ground. This can be a 10' Copper Ground Stake (best) or AC Power Ground. Run 10 AWG or 12 AWG wire as short a distance as possible, and avoid any bends in the wire.

Self-grounding Surge Protectors

Do not use surge protectors unless they are equipped with a separate ground wire or ground screw. Self-grounding Surge Protectors use the connector shell or Pin 1 as a ground path; however, the shell and Pin 1 are not always grounded.

AC Power Surge Protectors

AC Power Surge Protectors must be plugged into a properly grounded 3-wire socket. If a 3-wire socket is not available, have one installed by an electrician; do not use a 2-prong socket by cutting off the 3rd prong on the plug, or by using a 3/2 converter, or the surge protector will be rendered useless.

Terminating Cable Shields

Connect cable shields on data cables at one end only. You may terminate the cable shield to the same ground as the surge protector. Leave the cable shield unconnected at the opposite end.

More Information

For more information on lightning, including additional lightning protection methods and a US lightning density map, see Secura Key Applications Bulletin #28 on our website. (www.securakey.com)

CONNECTING THE DTK-CR (READER PROTECTION)

The DTK-CR is a multi-line surge suppressor that can protect card readers and keypads from damaging power surges. It can be used between an SK-ACPE panel and any wiegand-output reader/keypad. This is especially useful where readers are located on gates and parking control equipment. It may also be used to protect standalone access control units.

Locate the DTK-CR at least three (3) cable-feet away from the unit to be protected.

Connect the green ground wire to a dependable earth ground, using a heavy gauge cable (12 or 14 AWG recommended). Keep the wire run to the grounding location as short as possible.

Wiegand-output Card Readers and Keypads

Connect the Wiegand "0" and Wiegand "1" wires from the control panel to DATA IN. Connect the wiegand "0" and "1" wires from the reader to DATA OUT.

Connect the reader power lines from the control panel to 5-12V IN. Connect the power wires from the reader to 5-12V OUT.

Connect the "red" LED and "green" LED lines from the control panel to LED IN. Connect the "red" and "green" LED lines from the reader to LED OUT.

If you are operating a 24 volt electric lock or strike, you can protect it also by connecting the lock power lines to 24V IN and OUT.

CONNECTING THE DTK-XR (DATA LINE PROTECTION)

The DTK-XR is a multi-line surge suppressor that can protect an SK-ACPE control panel, or other access control unit from damaging power surges.

Locate the DTK-XR at least three (3) wire-feet away from the unit to be protected.

Connect the green ground wire to a dependable earth ground, using a heavy gauge cable (12 or 14 AWG recommended). Keep the wire run to the grounding location as short as possible.

If you are using 24 volts to power the access control unit (recommended) connect the power supply to 24V IN and connect the access control unit to 24V OUT. If you are using 12 volts to power the access control unit, connect the power supply to 12V IN and connect the access control unit to 12V OUT.

If the access control unit is connected to other units via RS-485 you may connect the "A" and "B" lines of the RS-485 twisted pair to 6V IN and 6V OUT.

If you are using a dial-up modem, you may protect the modem by running the "Tip" (usually green) and "Ring" (usually red) phone lines to TELCO IN and connect the phone jack to TELCO OUT.

APPENDIX G

What's new, and what has not changed in the SK-ACPE?

The SK-ACPE is Secura Key's replacement for the legendary SK-ACP. The "E" indicates the built-in Ethernet capability. The main reason for this upgrade is the obsoletion of the ACP's 16-bit Hitachi main processor unit. Due to the large number of legacy systems in the field, we have designed the SK-ACPE as a drop-in replacement for the SK-ACP. While the SK-ACPE is almost functionally identical, we have also included some long-needed improvements made possible by the powerful new ARM Cortex M3, 32-bit RISC processor.

• 1. This unit is functionally identical to the SK-ACP. It will work with older versions of SK-NET software, including Versions 3, 4 and 5.
• 2. Connectors and their functions are identical to the SK-ACP. You can replace an older board with a new one without rewiring the connectors. Note that connectors J3 and J4 are now located on the side of the board.
• 3. The Ethernet Adapter is now integrated into the panel. Connect to the LAN via RJ-45 connector J10 at the lower right-hand corner of the board. A separate module is not required. Multiple Ethernet connections in one system require SK-NET-MLD. IP Addresses must be configured using a terminal program (See Appendix D).
• 4. Status LED functions and locations have been changed see Figure 4 for details.
• 5. The jumper that changes input circuits from NC to NO has been removed . On the SK-ACPE, this setting is now changed in the SK-NET software (Version 5.1 is required). If you do not have Version 5, the inputs will default to NC.
• 6. A new Jumper JP1 enables RS-232 signals either at J12 or J11 and J10 (See Figure 3). Enabling RS-232 at J12 allows the use of the optional SK-WLSE-LAN wireless LAN Module. Enabling RS-232 at J11 and J10 allows the connection of a computer at the Field Service Port J11 or wiring of a serial connection to J10. The SK-WLSE-MOD is an entirely new module, and is not compatible with the SK-WLS-MOD module used with the SK-ACP.
• 7. The RJ-11 Jack has been removed. The SK-QUICKCONN and SK-CBLSA cables cannot be used to connect a computer to the panel's RS-232 port. A new cable, RS-232E, is required to connect a computer to the J11 Field Service Port.

• 8. The Reset Button has been moved it is next to connector J2.
• 9. AC Power is now recommended, due to a redesigned power supply. A 16.5VAC 40VA transformer such as SK-XFRMR can be used to power the board. 24VDC power is also recommended, using a DC supply such as SK-DCPWR.
• 10. Gas discharge tube surge protectors are now included on the RS-485 bus (J8) which interconnects multiple panels, and can be used to connect back to the host PC. These devices will greatly improve surge protection of the panel, but external surge protectors are still highly recommended in lightning-prone areas (see Appendix F4, F5).
• 11. A Chassis Ground Terminal has been added to the PCBA (left of J8). To allow the on-board surge suppressors to discharge to ground, you must connect this terminal to Earth Ground, using the supplied ground lug and 10 AWG wire (see Figure 3).
• 12. The panel now includes battery monitoring circuitry which can report low battery or AC failure conditions to SK-NET (Version 5.1 is required). These conditions are also indicated at LED 2.
• 13. On-board memory has been increased , allowing up to 10,000 stored transactions to be buffered instead of 4800, and allowing up to 65,535 cardholders to be limited use cards instead of 4000 (SK-NET Version 5.1 is required).
• 14. The panel now includes an enclosure tamper input (J7, pins 1&6) which can be connected to optional enclosure tamper switch SK-TS. (SK-NET Version 5.1 is required.)
• 15. The Serial Transaction Printer function must now be configured using a Terminal Program. (See Appendix D).
• 16 . The Power Reset function has been enhanced (See Appendix E, section 1.8).
