Mounting Procedure
1. Select a mounting location over the center of the door or doors to be covered. The target must walk
directly toward the detector.Mount the detector on the ceiling,wall,or door frame.
2. Remove the front cover from the detector.
3. Route the wiring as necessary through the wiring entrance(refer to the item 3 description and oper- ation).For surface wiring,use the break out wiring entrance on the front cover(at the same end as the wire entrance).
4. Loosely mount the back cover to the mounting sur- face using the supplied mounting screws.
5. Aim the detector for the desired coverage.
6. 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 throgh the coverage area,to- ward 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 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 |
| Unit does not power up | No or low imput power. | Apply proper input voltage. |
| Input power polarity reversed. | Correct wiring polarity. |
| Alarm LED does not light | 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. |
