Infrared Ceiling Mounted Occupancy Sensor
Cat. No. LIRO H
To be used with 24VDC
LPCS Series Power Pack Class II Low-Voltage Wiring
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 and proper masking 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 infrared sensor that works with the LPCS Series
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.
Infrared motion detection gives higher false triggering immunity that yields a sensor with
excellent performance.

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 touch the surface of the lens. Clean outer surface with a damp cloth only.

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 and proper masking 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.
