DESCRIPTION
The BZ-150 power pack is the foundation for any low voltage lighting control
system. The BZ-150 supplies low voltage power to occupancy sensors and other
control devices, switching line voltage in response to signals from control devices.
The BZ-150 power pack is attached to existing junction boxes or mounted into
fi xture wiring trays.
Low voltage wiring should use at least 22-gauge wire. High voltage connections
should use at least 14-gauge. Always check local building codes. After initial
wiring is complete, check wiring diagrams to verify the power pack is wired
correctly. Improper wiring can cause damage to the power pack, lighting system,
occupancy sensor and other control devices.
