BZ-50
The BZ-50 and BZ-50RC power packs are the foundation for any low voltage lighting control system. The BZ-50 and BZ-50RC supply
low voltage power to occupancy sensors and other control devices, switching line voltage in response to signals from control devices.
The power pack is attached to existing junction boxes or mounted into fixture wiring trays.
High voltage connections should use at least 14-gauge. For the BZ-50, low voltage wiring should use at least 22-gauge wire. The
BZ-50RC supplies low voltage power via shielded RJ45 cable. Always check local building codes. After initial wiring is complete,
check wiring diagram to verify power pack is wired correctly. Improper wiring can cause damage to power pack, lighting system, and
occupancy sensor.

1. Make sure power has been turned off at the circuit breaker.
2. Connect wires as shown in in the following diagrams, depending
on the model and application.
At least three sensors can be powered by the power pack.
Installation Notes
1. Power packs should be installed in accordance with state, local and national electrical codes and requirements.
2. Power packs are designed to attach to existing or new electrical enclosures with 1/2 inch knockouts.
3. For the BZ-50, most applications require UL listed, 18-22 AWG, 3-conductor, Class 2 cable for low voltage wiring. For plenum
return ceilings, use UL listed plenum-approved cables.
For the BZ-50RC, connect an FS-C1 or FS-C3 cable between the RJ45 jack-equipped sensor and the BZ-50RC, as appropriate
for the distance between the sensor and power pack. Other cable accessories are shown in the Ordering information section.
NOTE: The BZ-50RC can connect to a sensor with standard wiring terminals by using an FS-C2 cable.
4. The BZ-50 BZ-50RC are Class 2 Output Power Supplies, suitable for parallel interconnection of up to 10 units maximum. These
powerpacks are UL Listed for Interconnection of Power Sources in accordance with the National Electric Code.
5. Refer to occupancy sensor data sheet to determine maximum number of sensors. Power pack mA output is 225mA.
