WIRE DESIGNATIONS
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 OSCxx, OSWxx, ODCxx, and ODWxx Series Occupancy Sensors. The OSP
power packs can also supply power to the OSA20, Add-A-Relay. 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: Loads that exceed the ratings of a single power pack can
be connected to an Add-A-Relay, which is powered from the low-voltage output
of the power pack (OSPxx). The Add-A-Relay contains the load switching and
HVAC relays and is powered by an OSPxx Power Pack.
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.
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.
• 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 Diagrams.
- Line voltage miswired. Verify wiring connections per appropriate
Wiring Diagrams.

WARNING: TO AVOID FIRE, SHOCK, OR DEATH; TURN OFF POWER
at circuit breaker or fuse and test that power is off before wiring!
2. Mount power pack per desired application:
A. To mount outside 4”x4” junction box using 2” EMT nipple, refer to
Figure 1. Wire per Step 3A and 3B.
B. To mount inside 4”x4” 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.

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.
3B. 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.
4. Refer to sensor Installation Instructions for further details.
5. Restore power at circuit breaker or fuse.
