#8-32 x 1-1/2" Screw (2) Plastic Washer (1)
DESCRIPTION
The Occupancy Sensor is a low-voltage ultrasonic sensor that works with the OSPxx
Series and CN100 power pack to automatically control lighting. The sensor turns the
lights on and keeps them on whenever occupancy is detected and will turn them off
after the ‘delayed-off time’ has expired.
The sensor continually analyzes and adjusts to changing conditions. The sensor uses
the latest microprocessor-based technology which permits it to continually adjust and
optimize its performance.
Ultrasonic (doppler shift) motion detection gives maximum sensitivity that yields a
sensor with excellent performance.
INSTALLING YOUR OCCUPANCY SENSOR
NOTE: Use check boxes when Steps are completed.
WARNING: TO AVOID FIRE, SHOCK, OR DEATH; TURN OFF
POWER at circuit breaker or fuse and test that power is off before wiring!

5. Push the wires into the hole in the ceiling tile and insert the threaded rod until the
sensor is flush with the tile.
6. Insert wires through the hole in the included washer, then place the included washer
over the rod and screw on the included hex nut.
7. Class II Wiring: Connect low-Voltage wires from Power Pack to Sensor per WIRING
DIAGRAM as follows: Twist strands of each lead tightly and, with circuit conductors,
push firmly into appropriate wire connector. Screw connectors on clockwise making
sure that no bare conductor shows below the wire connectors. Secure each connector
with electrical tape.
8. Rotate the sensor to the desired orientation. Note that the sensor base and back cover
are keyed. To lock the device in place, ensure that the arrows are not aligned.
9. Restore power at circuit breaker or fuse to Power Pack.
INSTALLATION IS COMPLETE.

Typical Installations:
Listed are 3 typical installation options (A, B, and C). Choose one that
best suits your needs. Other methods of installation may be possible but
they have not been described here.
A. Drop Ceiling Installation (Mounting Option A):
NOTE: Use the threaded rod included.
1. Select location for mounting of sensor for your application (refer to Mounting
Location Diagram).
2. Use the supplied threaded rod or other methods to make a hole (1/2" to 1") in the
ceiling tile just large enough to pass the body of the threaded rod through.
3. Insert the sensor wires through the flared end of the threaded rod. Position the
threaded rod to the base of the sensor.
4. Insert the flared end of the threaded rod into the opening in the bottom of the sensor
and twist to lock into place.

C. Junction Box or Surface Mount Raceway Installation (refer to
Mounting Diagrams):
NOTE: Listed below are suggested JUNCTION BOX installation applications which
require mounting to conduit in one of the following three ways:
B. Wallboard or Drop Ceiling Installation (Mounting Option B):
NOTE: You may use the mounting screws, nuts and washers included, or screws in
combination with commercially available wall anchors.
1. Select location for mounting of sensor for your application (refer to Mounting
Location Diagram).
2. Make a hole in the ceiling tile or wallboard large enough to pass the wire connections
and wire nuts through (approximately 1" diameter).
3. Remove the back cover of the sensor. Hold the back cover and body of the sensor and
rotate until the two arrows line up and pull apart.
4. Install back cover of the ceiling sensor to the wallboard or drop ceiling using the
included screws, nuts and washers, or screws in combination with commercially
available wall anchors.
5. Class II Wiring: Connect low-Voltage wires from Power Pack to Sensor per WIRING
DIAGRAM as follows: Twist strands of each lead tightly and, with circuit conductors,
push firmly into appropriate wire connector. Screw connectors on clockwise making
sure that no bare conductor shows below the wire connectors. Secure each connector
with electrical tape.
6. Push wire connections through the center hole of the back cover and into the ceiling.
7. Secure the sensor body to the back cover by aligning the arrows. Lock it by turning the
sensor such that the arrows do not line up.
8. Rotate the sensor to the desired orientation.
9. Restore power at circuit breaker or fuse to Power Pack. INSTALLATION IS
COMPLETE.
