DESCRIPTION
The power pack contains a power supply, a load switching relay and on some models, a HVAC relay. The power supply provides Class II low-voltage power for Philips LRM2250,
LRM2255, LRM2260, LRM2265, LRM2270, LRM2275, LRM2280 Occupancy Sensors. The relay in the power pack is controlled by the occupancy sensors connected via the 22
Gauge Blue "occupancy" wire. Multiple occupancy sensors can be connected to a single power pack in order to fully cover an area.
The power packs include zero cross switching circuitry to minimize inrush current associated with incandescent and electronic ballasts. This reduces wear and tear on the relay
contacts making the power pack last longer.
Application Notes:
1. When a lighting load exceeds a single power pack's rating, the load can be split between multiple power packs. The low voltage occupancy input (Blue wire) and DC return
(Black wires) of the power packs must be connected together for all power packs to operate together as one. Connect the Blue (occupancy) wires of all power packs and sensors
together. Connect the Black (return) wires of all power packs and sensors together. Connect the Red (+24VDC) wires of the sensors to the Red wires of only one power pack.
Never connect the Red (+24VDC) wires of two different power packs together.
2. When more sensors are required than one power pack can supply, multiple power packs can be used to supply power to the occupancy sensor, but not switch any load. The
primary power pack is the power pack switching the load. The secondary power packs only provide low voltage power to the occupancy sensor(s). Connect as many sensors
to the primary power pack as possible (see current capacity section below), by connecting the Red wires of the sensors to the Red wire (+24VDC) of the primary power pack.
Connect the Red wires (+24VDC) of the remaining sensors to the Red wires of the secondary power pack. Connect the Black (return) wires of all power packs and all sensors
together. Connect the Blue (occupancy) wire of all sensors together to the Blue wire (occupancy) of the primary power pack. Never connect the Red (+24VDC) wires of two
different power packs together.
FCC COMPLIANCE STATEMENT ( LCA2285 Only )
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.

INSTALLATION
WARNING:
TO AVOID FIRE, SHOCK, OR DEATH; TURN OFF POWER AT CIRCUIT BREAKER OR FUSE AND TEST THAT POWER IS OFF BEFORE WIRING!
WARNING:
TO BE INSTALLED AND/OR USED IN ACCORDANCE WITH APPROPRIATE ELECTRICAL CODES AND REGULATIONS.
WARNING:
IF YOU ARE NOT SURE ABOUT ANY PART OF THESE INSTRUCTIONS, CONSULT AN ELECTRICIAN.
WARNING:
USE THIS DEVICE WITH COPPER OR COPPER CLAD WIRE ONLY.
WARNING:
DISCONNECT POWER WHEN SERVICING FIXTURE OR CHANGING LAMPS.
TO INSTALL:
1. Mount power pack per desired application:
A. To mount outside 4" x 4" junction box using 2" EMT nipple, refer to Figure 1. Wire per Step 3A and 3B.
B. To mount inside 4" x 4" junction box, refer Figure 2. Wire per Step 3A and 3B.
• Ensure that conduit/cable entry clamp is located in corner of junction box.
• Dress wires to provide enough clearance when device is installed.
CAUTION: Low-voltage wires must also be dressed so they are separate from the high voltage (Class I) conductors. Refer to local building codes for the appropriate installation
requirements for the low-voltage wiring. Jacketing over the low-voltage wires may be required to provide appropriate insulation from the high-voltage wiring.
C. To mount inside ballast cavity of light fixture, refer Figure 3A. Wire per Step 3A and 3B.
CAUTION: Low-voltage wires must also be dressed so they are separate from the high voltage (Class I) conductors. Refer to local building codes for the appropriate installation
requirements for the low-voltage wiring. Jacketing over the low-voltage wires may be required to provide appropriate insulation from the high-voltage wiring.
D. To mount outside ballast cavity of light fixture, refer Figure 3. Wire per Step 3A and 3B.
2A. Line Voltage Wiring: Remove 5/8" (1.6 cm) of insulation from each circuit conductor. Make sure that ends of conductors are straight. Connect lead wires from Power Pack to
LINE circuit per appropriate 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.
2B. Class II and HVAC Wiring: Connect Low-Voltage wires from Power Pack to Sensor per appropriate 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.
3. Refer to sensor Installation Instructions for further details.
4. Restore power at circuit breaker or fuse. INSTALLATION IS COMPLETE.
OPERATION
Close Relay: When the attached occupancy sensor detects motion, it will apply +24V to the Occupancy wire causing the relay to close. This includes the HVAC relay on equipped models.
Open Relay: When the attached occupancy sensor does not detect motion the relay will open. This includes the HVAC relay on equipped models.
TROUBLESHOOTING
• Lights Flickering
- Lamp has a bad connection.
- Wires not secured firmly with wire connectors.
• Lights do not turn ON
- Circuit breaker or fuse has tripped.
- Lamp is burned out.
- Lamp Neutral connection is not wired.
- Low-voltage miswired. Verify wiring connections per appropriate Wiring Diagarms.
- Line voltage miswired. Verify wiring connections per appropriate Wiring Diagarms.
• Lights stay ON
- Constant motion. To Test: Adjust sensor; remove motion source. If unsatisfactory, move sensor.
• Light turns ON too long
- Adjust sensor.
