4. INSTALLATION
Mounting Procedure
1. Select a mounting location over the center of the door or doors to be covered. Mount the detector on the ceiling wall or door frame.
2. Remove the front cover from the detector.
3. Loosely mount the back cover to the mounting surface using the supplied mounting screws.
4. Aim the detector for the desired coverage.
. Mount the front cover on the detector.
Long Range/Short Range Adjustment
The OD-22 can be set to detect individuals at either a long rang(several steps from the door) or at short range (immediately in front of the door).If the build- ing includes a lengthy approach to the exit doorway and no other foot traffic in the area, choose the long range setting.

Setup and Testing
1. Apply power to the unit.
2. Wait at least 3 min for the detector to settle.
3. Test the unit by walking directly through the coverage area toward the door.
4. Aim the detector up or down if necessary to obtain the proper coverage.
5. Check that the relay latch time is sufficient to adjust if necessary.
6. After confirming proper operation, replace the cover and walk test one more time to ensure the coverage has not changed.
6. WIRING
Latch Time
DIP Switch 1,2, and 3 set the relay time. Latch time is adjustable from 0.5 sec to 64 sec. It indicates the amount of time the relay can remain active after the detector first sees motion.

7. TROUBLE SHOOTING AND MAINTENANCE
TROUBLE | TROUBLE CAUSE | REMEDY |
the unit does not power up | No or low input power. | Apply proper input voltage. |
Input power polarity reversed. | Correct wiring polarity. |
Alarm LED does not light | the LED jumper is set to “LED OFF”. | Set LED jumper to “LED ENABLE” |
Incorrect sensor mounting height | Increase /decrease mounting height |
LED indicates light,no signal output | Incorrect wiring at output terminals | Correct wiring fault. |
Lightning damage | Replace sensor. |
Unit continues to operate after the input power has been disconnected. | The wire to the “V-” power input was discon- nected, the “V+” is still connected. | Disconnect wire from the “V+” power input. |
MAINTENANCE
INSPECTION: An inspection of this unit should be made periodically, consisting of but not limited to all mounting, wiring
and the condition of the interior area and components.
CLEANING: Clean the plastic parts of this unit with a soft, clean, cloth dampened with water.
