BZ-150-U is BAA and TAA compliant (Product produced in the U.S.)
The BZ-150 power packs 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 power pack is
attached to existing junction boxes or mounted into fixture wiring trays.
High voltage connections should use at least 14-gauge. Low voltage wiring should use at least 22-gauge wire. 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
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-150, 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.
4. The BZ-150 is a Class 2 Output Power Supply, suitable for parallel
interconnection of up to 10 units maximum. See wiring diagrams. This powerpack
is 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.
