MOUNTING THE SENSOR
Directly to Ceiling
1. Attach the plastic spring clips to the edge of the sensor in the slots provided.
2. Cut a 3.5” to 4” round hole in the acoustic ceiling tile at the mounting location. A 3.5” hole
is recommended for a secure fit.
3. Pull the low voltage wire from the power pack to the sensor through the hole.
4. Connect the low voltage wires to the appropriate terminals on the sensor.
5. Push the sensor up through the hole until the Spring Clips hold the sensor securely in
place.
6. Snap the front cover onto the sensor.
Using an Octagonal J-Box
1. Pull the low voltage wires from the power pack into the J-Box through the conduit
knockout.
2. Connect the low voltage wires to the appropriate terminals on the sensor.
3. Loosen the appliance mounting screws attached to the J-Box
4. Align the sensor in the J-Box so that the mounting screws on the box match the key
holes on the sensor’s rear housing.
5. Push the sensor up into the J -Box and twist it so that the mounting screws are seated in
the keyhole slots.
6. Tighten the two screws to secure the sensor to the J-Box.
7. Snap the front cover onto the sensor.

SENSOR ADJUSTMENT
NOTE: This unit is pre-set for basic operation as described in this guide. Adjustment is optional.
The sensors are factory preset to allow for quick installation in most applications.
Verification of proper wiring or coverage, or customizing the sensor’s settings can
be done using the following procedures. To make adjustments, open the Front
Cover with a small screwdriver.
Before making adjustments, 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. Set the Time Delay to the
desired settings. See
DIP Switch Setting
.
To Test Occupancy Sensors
1. Ensure the Time Delay is set for
Test Mode*
using the “Test Mode/20
minutes” setting. (DIP Switches 1, 2, & 3 are
OFF
).
2. Ensure that the Ultrasonic Sensitivity trimpot is set to about 70%, clockwise.
3. Remain still. The LED should not flash. The lights should turn off after 5
seconds. (If not, see
Troubleshooting
.)
4. Move about the coverage area. The lights should come
ON
. Adjust the Ultrasonic Sensitivity as necessary to provide the desired
coverage (Green LED indicates activation from the ultrasonic sensor).
When testing and adjustment are complete, reset DIP Switches to the desired settings, and replace the cover on the sensor.
*Test Mode is a temporary state that starts when you first set the sensor’s DIP Switches for the “Test Mode/20 minutes” (Switches 1, 2,
3
OFF
). If you need to invoke the Test Mode and the DIP Switches are already set for Test Mode/20 minutes, toggle DIP Switch 1
ON
,
then back to the
OFF
position. This provides a 10 minute test period. During the test period, the Time Delay is only 5 seconds.
