Lights do not turn off automatically:
1. The sensor may be experiencing activations from outside the controlled area
or from some type of interference (see “Unwanted Sensor Activations” below).
2. Check all sensor and power pack wire connections.
3. Disconnect power pack’s blue wire:
If the lights do not turn off, replace power pack. Reconnect blue wire.
If the lights turn off, the problem may be in the sensor–to check:
Reconnect the blue wire.
Turn sensitivity and time delay to minimum and allow the sensor to time out.
If the lights turn off, the sensor is working properly (see
“Sensor Adjustment” for readjustment of sensor).
Unwanted Sensor Activations (LED flashes):
• Possible causes
1. Improper sensor location or inadequate masking causing
detection outside of desired coverage area.
2. The PIR sensitivity may be set too high.
3. Sensor located too close to HVAC or VAV vents with heavy air flow.
• Possible solutions
1. Mask the lens to reduce PIR coverage (see “Masking
the PIR Lens”, under “Placement Guidelines”).
2. Set DIP switch 7 to OFF and see if the excess activations stop.
3. Relocate the sensor.
