INSTALLATION INSTRUCTIONS

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.

DESCRIPTION

The Occupancy Sensor is a low-voltage ultrasonic sensor that works with the OSP

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!

WARNINGS AND CAUTIONS:

•To be installed and/or used in accordance with appropriate electrical codes and regulations.

• If you are unsure about any part of these instructions, consult a qualified electrician.

• Sensors must be mounted on a vibration free surface.

• All sensors must be mounted at least 6 feet away from air vents.

• Do not mount sensors closer than 10 feet from each other.

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.

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.

Figure 2 (Cat. No. OSC05) Field-of-View Ranges TABLE 4: SWITCH SETTINGS OPERATION Motion detection by the ultrasonic sensor will turn on the lights as well as keeping them on. When motion is not detected, the lights will turn off after the delayed-off time. • Delayed-Off time – The sensor is designed to turn the lights off if no motion is detected after a specified time. This length of time is called the delayed-off time and is set using the timer (Black) knob on the sensor.
