SENSOR ADJUSTMENT
THE SENSORS ARE FACTORY PRESET
*
TO ALLOW FOR QUICK INSTALLATION IN
MOST APPLICATIONS. However, verification of proper wiring or coverage, or customizing
of the sensor’s settings can be done through the following steps.
Before starting, make sure the office furniture is
installed, lighting circuits are turned on, and the
HVAC systems are in the overridden/on position.
VAV systems should be set to their highest
airflow.
There is a warm-up period when power is
first applied to the sensor of up to one and a
half minutes.
1. For testing, set the Time Delay to minimum,
15 seconds. See chart below for DIP switch
configurations.
2. Ensure that the Sensitivity trimpot is set to
maximum, fully clockwise.
3. Remain still. The lights should turn off after
approximately 15 seconds (If not, see
Troubleshooting).
4. Set the desired Time Delay.
5. Readjust the angle of the sensor if necessary.
Time Delay:
• The Time Delay is set with DIP Switches
1 thru 4.

TROUBLESHOOTING
Lights do not turn on with occupancy, and the following condition exists:
• LED does NOT flash:
When power is initially applied to the sensor, there is a warm-up period of up to
60 seconds before the LED is active.
1. Check that the circuit breaker has been turned back on.
2. Check the Sensitivity setting. Increase (clockwise) as needed.
3. Check all sensor and power pack wire connections.
4. Check for 24VDC at sensor (red or black wires).
- If 24VDC is present, replace the sensor.
- If 24VDC is not present, check that high voltage is present to power pack.
If it is, replace power pack.
• LED does flash:
1. Check all sensor and power pack wire connections.
2. Check for 24VDC at the power pack’s blue wire connection to sensor while someone
moves in front of sensor to activate the LED. If there is no voltage, replace the sensor.
If there is voltage, replace the power pack.
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” next page).
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 number 1. above, and
“Sensor Adjustment” for readjustment of sensor).

Unwanted Sensor Activations (LED flashes):
• Possible causes
1. Improper sensor location or angle adjustment causing detection outside of desired
coverage area.
2. Sensitivity 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 lens”, under “Coverage
Patterns”).
2. Reduce the sensitivity (counterclockwise) as needed (see “Sensor Adjustment”).
3. Adjust the sensor angle (see “Sensor Adjustment”).
4. Relocate the sensor.
Override:
To override all sensor functions, set DIP switch #5 to on.
This bypasses the occupancy control function of the sensor but still allows the lights to be
manually controlled with a toggle switch.
