SENSOR ADJUSTMENT
NOTE: There is a 40 sec warm-up period when power is first applied to the unit.
The sensors are factory preset to allow for quick installation in most applications. Follow
this procedure to verify the sensor coverage and customize the settings.
1. Remove the front cover. Look for a small opening on periphery of cover. With the help of
a flathead screwdriver, snap off front cover.
2. Make sure all the furniture in the sensing area is installed, the load is turned ON and the
HVAC systems are in the Override position.
3. If there is a VAV system, set it to the highest airflow. Settings are modified by either 2
trimpot dials, for Light and Ultrasonic sensitivity, and 8 DIP switches for Trigger Mode,
PIR sensitivity, override, and time delay. See Figure 5 for location.
ADJUST THE AMBIENT LIGHT LEVEL
The Ambient Light Level feature enables the user to adjust the ambient light level needed
to be detected before the sensor turns the load ON. Remove the cover from the sensor and
adjust the lighting from the light level dial on the sensor (see Figure 5). You can set the dial
anywhere between + or – to obtain the optimal brightness configuration for the room.
ULTRASONIC SENSOR SENSITIVITY
The Ultrasonic sensor sensitivity is set with ULTRASONIC trimpot (see Figure 5). Increase
sensitivity for larger rooms, decrease sensitivity to avoid false triggers in smaller rooms and
near doorway or heat source. Factory set to 50%.
PIR SENSOR SENSITIVITY
Adjust the PIR sensitivity level with DIP Switch (1). The Up position sets the sensitivity to
100%, while the down position adjusts the sensitivity level to 50%. Factory setting: 100%.
TRIGGER MODE
The sensor trigger mode is set with DIP Switches 2, 3, 4. The unit can be set for motion
detection to use:
BOTH – requires motion detection by PIR and Ultrasonic sensors
EITHER – requires motion detection by one of the two sensor technologies
PIR – requires motion detection by PIR
ULTRASONIC – requires motion detection by ultrasonic sensor
There are 6 Trigger modes set with DIP Switches 2, 3, 4 as follows (see Table 1):
TIME DELAY
The sensor will hold the load ON as long as occupancy is detected. The user defined TIME
DELAY countdown starts when no motion is detected. After TIME DELAY, loads will be turn
OFF. The TIME DELAY is set with DIP switches 5, 6, 7, as follows (see Table 2):
OVERRIDE
DIP Switch (8) in down position, sensor will operate normally. DIP Switch (8) in up position
will maintain sensor ON.
Load does not turn on with occupancy:
Load does not turn off automatically:
Unwanted Sensor Activations (LED flashes):
Warranty service is available by either (a) returning the product to the dealer from whom the unit was purchased or (b) completing a warranty claim online at www.intermatic.com. This warranty is made by: Intermatic
Incorporated, 1950 Innovation Way, Suite 300, Libertyville, IL 60048. For additional product or warranty information go to: http://www.Intermatic.com or call 815-675-7000.

TROUBLESHOOTING
Red LED does not flash:
1. When power is initially applied to the sensor, there is a warm-up period of 40 sec before LED becomes active.
2. Make sure PIR sensitivity is set to 100% (DIP Switch 1).
Green LED does not flash:
1. Ultrasonic sensitivity setting may need to be increased. Turn clockwise as needed.
Green LED flashes:
1. Reduce ultrasonic sensitivity by turning counter-clockwise until it only flashes when movement occurs.
Red LED flashes:
1. Reduce PIR sensitivity by setting to 50% (DIP Switch 1).
Possible causes:
1. Sensor located too close to HVAC or VAV vents with heavy air flow.
2. The ultrasonic sensitivity may be too high.
3. The PIR sensitivity may be set too high.
Possible solutions:
1. Relocate the sensor.
2. Reduce the ultrasonic sensitivity as needed.
3. Mask the lens to reduce PIR coverage.
