PRODUCT DESCRIPTION

DynaLock 6420 Series passive infrared "request-to-exit" sensor is specifically designed for applications involving coverage at the threshold of a doorway. A number of field selectable options and adjustments make it a compatible choice for access control applications, door strike release, alarm system shunting and automatic door operation.

PARTS DESCRIPTION

9 DO'S AND DON'T'S

• •Do not install the unit in places where it may be affected by rain.
• •Do not blind the unit by placing any object in the detection area.
• •Keep installation height within 13' (4m).

unable to distinguish between source.

•Adjust the detection area after installation.

[MAINTENANCE]

• 1. When the unit is soiled, clean the cover with a soft cloth moistened with a small amount of cleansing-solution. Do not use chemicals such as thinners or alcohol.
• 2. Check operation once a week. Do not fail to check operation whenever furniture in coverage area is moved.

2. ADJUSTMENT

•The 6420 PIR is designed to detect infrared energy variations

caused by the presence of a human body. Therefore, note that similar variations in conditions in the detection area, due to

other reasons, may cause the sensor to create an output as it is

1. Set the pattern selector to double or single door by Pattern Selector.

• 2. Set the arrow of the angle adjusting lever to detection area.
  • The arrow of the angle adjustment lever points to the detection area.
• 3. Walk test the unit to ensure proper detection pattern.
• Check the functioning of the unit once a week. This check should also be carried out whenever the detection area has been altered.

4 INSTALLATION

1) Select the mounting location and position of sensor (wall mount or overhead mount).

Mount the unit in the center of door.

Wall mount

Overhead mount

2) Separate the cover from the sensor unit.

Thumb ······ Push the window. Forefinger ···· Place finger on the knockout and pull this side to detach the cover. It will come off easily.

3) Drill the mounting hole.

Place the unit body on the mounting location and undermark the screw hole and wiring hole.

4) Mount the base.

Pull wires through the wiring hole and mount the unit body with the tapping screws provided.

5) Securing the cover

To lock the cover, pierce the cover locking screw hole. Insert cover locking screw and tighten. This is necessary for all UL installations.

WIRING

• •Run wires through the wiring ditch and insert to the wiring holes on the left side of the terminal unit.
• $\backslash bullet\; The\; terminals\; accept\; from\; AWG\; 14\; up\; to\; AWG\; 22.$
• •Connect attached resistor $(82\backslash ,\backslash Omega\backslash ,,\backslash ,3\backslash mathrm\{W\})$ in series with the power input when supply voltage is 20 to 24VAC.
• •The NC and NO output will reverse according to the "relay mode" set up. (See 6 for explanation)
• •The unit is intended to be powered by either a UL Listed power supply or a UL Listed Class 2 transformer.

[TERMINAL ARRANGEMENT]

6 OPERATION AND FUNCTION

1) Operation

The sensor initiates two relay outputs and turns on the LED when it detects human body.

The hold time of the relay can be adjusted by the timer control

The hold time does not retrigger by detection while the relay is activated.

2) Set up

The following functions can be set up by the 2 dip switches on the side of the inner cover.

Relay mode

Relay mode can be selected by dip switch 1.

Relay mode "A"

This mode selects "FAIL SAFE" (OPENING DOOR OR UNLOCK ELECTRIC STRIKE) operation in the event of power failure.

Relay mode "B"

This mode selects "FAIL SECURE" (CLOSING DOOR OR LOCK ELECTRIC STRIKE) operation in the event of power failure.

SET UP	RELAY MODE	CONTACT
1	Α	Fail safe if power fails (FACTORY SET)
1	В	Fail secure if power fails

*Note that NC and NO output terminal configuration reverses according to the relay mode.

LED mode

The LED operation can be disabled by dip switch 2.

SET UP		LED
2	OFF	Disabled
2	ON	Turns on during the relay hold time. (FACTORY SET)

3) Adjustment

The following functions can be set up by the 2 control dials on the bottom of the inner cover.

Sensitivity

The detection sensitivity can be adjusted.

Turn the dial by the sensitivity control clockwise for higher sensitivity and counterclockwise for lower setting. (FACTORY SET: MEDIAN)

Output hold time

The hold time for the 2 output relays and the LED can be adjustable between approximately $0.25~\{\backslash rm\; sec.\}$ and $60~\{\backslash rm\; sec.\}$ (FACTORY SET $0.25~\{\backslash rm\; sec.\}$ )

7 OPERATION CHECK

• (1) After wiring, set the LED to the on mode and check the operation. It takes approx. 1 minute for "warm up" after turning power on.
• (2) Confirm the detection zone by walk test.
• (3) Check the operation of the connected equipment.
• (4) If necessary, make fine adjustment.

8 TROUBLESHOOTING

Solve possible problems according to the following table. If normal operations cannot be restored by this means, contact either the dealer from whom you bought the unit or DynaLock.

Trouble	Check	Corrective Action
	No power supply, broken wire or improper voltage.	Correct power supply or replace broken wire.
Completely inactive	Cover shielded by substances (including glass).	Remove the substances.
	Improper area adjustment.	Readjust the protection area setting.
Sometimes inactive	Improper area adjustment.	Readjust the protection area setting.
	Cover face is soiled with dust or water drop.	Clean the cover with soft cloth. (Do not use chemicals such as thinners or alcohol.)
	Not yet 1 minute after power turned on	Allow for warming up time (about 1 min.)
Activated when no person has passed	Unstable power voltage.	Stabilize the power voltage.
	Something moving in protected area or too rapid temperature variations.	Remove the cause.
	Large electrical noise source such as power machine nearby or its wiring close to that of sensor.	Relocate device.
	Intense reflection of sun light or head light shining on the sensor.	Relocate device. Shield with a blind.
	Is the sensor reacting to passersby outside ?	Readjust the protection area.
The alarm LED lights,	Poor contact output connection or broken wire or short circuit.	Check the wiring or connection.
but connected units are inactive	Contact output is not working.	Check the contact output terminal using a tester.
are mactive	Is the connected unit operation normal ?	Check the connected unit.
