1.2 Product Description

The 242iLW keypad features the most fl exibility and options available in a self-contained unit. It has an accessory relay board that provides an additional three relays. It can perform access control functions and also its four relay outputs can be assigned independently for timed operation or to latch. The 242iLW keypad can control up to four devices, and is perfect for controlling electronic locking devices, security systems, CCTV systems, automatic operators, or machinery.

The 212iLW keypad features a single-relay output to control any device requiring an on/off switch. The output is timed or latched and operated by a user's PIN code. Additionally, the 212iLW keypad provides basic keyless entry by controlling a door locking device where security is not an issue.

The 212iLW and 242iLW style keypads are designed for both indoor and outdoor fl ush mount applications. The electronics for each keypad are conformal coated in the manufacturing process in order to provide this level of application fl exibility. In addition, each keypad uses hardened keys to assure long-term, high-quality performance. Each keypad contains illuminated clear keys that make operation in low light situations easy and accurate. Both iLW style keypads mount to any standard single-gang electrical box or directly to any wall.

NOTE: This manual covers both the 212 and 242 model. All features referring to the additional relays and outputs are available only on the 242 model.

3. Keypad Tampering

To prevent tampering, a tamper switch can be installed in the single gang box used for mounting the keypad. The tamper switch must activate if the keypad is removed from the box and must disconnect power from the lock. The lock must be a fail-secure device, meaning the lock remains locked when power is removed. In addition, once the tamper device is activated, it must be confi gured so that it can only be reset from within the protected area. Only a Sentrol 3012 or Sentrol 3025T tamper switch can be used. The diagrams on the next page show the suggested mounting location for each device.

3.1 Tamper Power Supply

Our access system power supply is designed specifi cally for access control applications. It features a tamper circuit with a reset button mounted on the circuit board. Using the tamper switch as detailed and connected to the power supply tamper circuit, unauthorized opening of the case or prying the unit off the wall triggers this tamper loop, thus preventing the lock from being released until the reset button is pressed.

How to Order

● Access power supply with tamper circuit in cabinet: Model PWR/TMPR12P; Order Number 0-291200

Figure 1. Mounting a Sentrol 3012 Tamper Switch

Figure 2. Mounting a Sentrol 3025T Tamper Switch

4. Mounting

The keypad is designed to be fl ush mounted using a standard single-gang electrical box. In addition, it can be fl ush mounted directly to the wall surface by cutting a hole in the wall. To properly size the mounting and wire access hole, use the installation template on the last page in this manual and on the unit's container.

Mounting height can vary depending on requirements. An appropriate range is typically between 48 and 52 inches on center off the fl oor.

For outdoor installations, use a weatherproof backbox and seal the wire entry locations with silicone and provide a drain hole. In addition, use the anti-oxidant grease pack for the wire harness connectors.

5.2 Wiring the Keypad to a Maglock (Fail-Safe)

Use the following steps to connect the keypad to a Maglock (Fail-Safe):

• 1. Connect the red wire (V+) to the blue wire (common), and then connect them to the positive on the power supply.
• 2. Connect the gray wire (normally closed) to the positive on the Maglock.
• 3. Connect the black wire (V-) to the negative on the Maglock, and then connect them to the negative on the power supply.

Figure 5. Wiring the Keypad to a Maglock (Fail-Safe)

5.3 Wiring the Keypad to an Electric Strike (Fail-Secure)

Use the following steps to connect the keypad to an electric strike (fail-secure) (see Figure 6 for reference):

• 1. Connect the red wire (V+) to the blue wire (common), and then connect them to the positive on the power supply.
• 2. Connect the green wire (normally open) to the positive on the strike.
• 3. Connect the black wire (V-) to the negative on the strike, and then connect them to the negative on the power supply.

Figure 6. Wiring the Keypad to an Electric Strike (Fail-Secure)

5.4 Shunting a Normally Closed Zone

Use the following steps to use the keypad to shunt a normally closed zone:

• 1. Connect the blue wire (common) to the common connection on the door position switch.
• 2. Connect the green wire (normally open) to the normally closed connection on the door position switch.

Figure 7. Shunting a Normally Closed Zone

5.5 Wiring Remote Trigger as Request to Exit (REX) Button and Door Contacts

Use the following steps to connect the keypad to a normally open REX device and normally closed door switch:

• 1. Connect the brown wire (REX Input) to the normally open connection on the REX device.
• 2. Connect the white/orange (loop common) to the common on the REX device and the common on the door switch.
• 3. Connect the white wire (door loop) to the normally closed connection on the door switch.

Figure 8. Wiring a REX Button and Door Contacts

NOTE: By default, the REX function operates the virtual lock output only, but you can change this using Command 49. In addition, the door loop doesn't need to be closed for the REX function to operate, by default, but setting Option 8 to 0 under Command 30, programs the REX function to operate only when the door loop is closed. This prevents the REX from re-triggering when the door is open.

5.6 Wiring an Accessory Relay Board (242 Only)

The accessory relay board contains physical outputs 2, 3, and 4 shown in the table below.

Physical Output	Relay	Connector
2	K2	P1
3	K3	P2
4	K4	P3

Use the wire harnesses supplied with the relay board to connect to the relays. The wire colors are shown in the table below.

Wire Color	Relay Connection
Gray	Normally Closed
Blue	Common
Green	Normally Open

Figure 9. Wiring the Accessory Relay Board

5.7 Wiring an Integrated Access Control System Using the Accessory Relay Board

Physical outputs 2, 3, and 4 are defaulted to the alarm shunt, propped door, and forced door virtual outputs, respectively. Use the following steps to wire the alarm shunt, propped door alarm, and forced door alarm.

NOTE: You MUST wire a normally closed door switch, as shown in Figure 8 on Page 11, for these functions to work properly.

• 1. (Wiring the alarm shunt) Using P1 (K2), connect the blue wire (common) to common on the door switch. Connect the green wire (normally open) to the normally closed contact on the door switch.
• 2. (Wiring the propped door alarm) Using P2 (K3), connect the green wire (normally open) to the positive on the alarm device. Connect the blue wire (common) to the positive on the power supply. Connect the negative on the alarm device to the negative on the power supply.
• 3. (Wiring the forced door alarm) Using P3 (K4), connect the green wire (normally open) to the positive on the alarm device. Connect the blue wire (common) to the positive on the power supply. Connect the negative on the alarm device to the negative on the power supply.

Figure 10. Wiring and Integrated Accessory Relay Board

To install the relay board, plug the relay board onto P3 on the keypad. The relays must face up towards the keypad wire harness connector P2. Use the included tie wrap to bundle all the wires together from the keypad wire harness and relay board.

Figure 11. Plugging on Relay Board

6. Testing the Keypad

After installing the keypad, the manufacturer recommends that you perform the keypad self-test once a year, to ensure that the keypad works properly.

• 1. To perform the self-test, with the unit powered up, press the following keys on the keypad: 7890 # 123456 ✱
• If all 12 key presses are accepted, the keypad enters self-test mode.
• The LEDs alternate green, yellow, and red followed by the sounder beeping three times.
• 2. Verify that the master code works correctly. (The master code accesses program mode and activates the main relay to verify that the locking device is working.)

The default master code is 1234.

(If the default is not working, refer to Section 9.)

7. Programming

To enter program mode, press 99 # Master Code ✱. The yellow LED must then start blinking slowing (if not verify the master code is correct – refer to Section 9). The default Master Code is 1234.

NOTE: If auto-entry is enabled, the ✱ (asterisk) key is not used to enter Program mode.

To change the Master Code, enter:

1 # new Master Code ✱ new Master Code ✱ (When fi nished press the ✱ to exit program mode.)

Note: Refer to Section 7.4 for adding user codes

7.1 Programming Order

Toggle User	A toggle user latches the virtual lock output.
Standard User	Activates the virtual lock output using the lock duration programmed with Command 11.
Lockout User	This user type locks out users in user locations higher than the lockout user when the lockout user code is entered. For example, if the lockout user is programmed for user 20, any user in location 21 to 120 is locked out and their codes no longer work to gain access. A lockout is removed by entering the same lockout code. If another lockout code in another user location is entered, the lockout user location level is set to the new lockout user location. The master code and emergency users can't be locked out. The current lockout is cleared when program mode is entered. "Lockout activated" is indicated by two double beeps. "Lockout canceled" is indicated by one double beep. "Access denied due to lockout" is indicated by 1 long beep followed by 3 short beeps. "User lockout" can be enabled or disabled with Command 30.
Single Use Code	This code can only be entered once to gain access using the lock virtual output. Once used, this code is no longer active. A single use code can be verifi ed by entering 5 # code ✱. If the code is a single use code, the green LED fl ashes for ½ a second. An "invalid code" is indicated by 3 quick beeps.

Command/Action	Keys to Enter/Details
Emergency User	This user type is a standard user that can not be
	locked out by a lockout user.
Duress User	Entering a duress code activates the lock and
	duress virtual outputs. This allows you to trigger
	another device silently, such as an alarm, and
	still gain access in case of an emergency. When the two-part user option is enabled, two
	codes are required to gain access. A "Two-Part
	Type A" and "Two-Part Type B" user must enter
	their code (not necessarily in that order). After
	the fi rst code is entered, the LED alternates
	between red and green, indicating another code
	is required. The second code must be entered
Two-Part	within 15 seconds of the fi rst code. When two

8. Troubleshooting

Refer to this section if the keypad is not operating correctly as described in this manual.

Problem	Solution
The LEDs are slowly cycling from right to left and backlighting is off.	The keypad is designed to monitor the input voltage and this is an indication of under-voltage. The under-voltage threshold is set to 8.5 VDC, and when the voltage drops below this limit, the low voltage warning starts and backlighting is turned off. To solve, raise the voltage to between 12-24 V.
The LEDs are rapidly cycling from left to right and the keypad has lost all operation.	The keypad is designed to monitor the input voltage, and this is an indication of over-voltage. The over-voltage threshold is set to 36 VDC, and when the voltage rises above this limit, the over voltage warning starts and the keypad loses all operation. To solve, lower the voltage to between 12-24 V.
The master code does not work.	Perform the programming mode loopback and reset the master code using the programming command.
No LEDs are lit on the keypad.	Power is not reaching the keypad. Using a voltmeter, confi rm that there is voltage at the keypad on the red and black wires. If there is no voltage at the keypad, verify that there is voltage at the power supply. If there is no voltage at the power supply, call the manufacturer of the power supply. If there is voltage at the power supply but not at the keypad, verify there is no break in the wires, then check continuity in the whole length of the wire run. To verify that the keypad is working, you can power the keypad with a 12-Volt Battery.

DEALERS/INSTALLERS ONLY! End users must contact the dealer/installer for support. If the keypad still does not work after troubleshooting, please call the Technical Services department at 1-800-421-1587.

9. Wire Harness Loopback Connections

If the Master Code is either not working or forgotten, power down the system, connect the wire harness as shown in Figure 12 below, and then power the system up again. The unit should now be in program mode. Next, change your Master Code using the programming command and power down the system and restore the wire harness to its original confi guration and power the system back up.
