DESCRIPTION AND OPERATION
The BZ-2xx series of power packs are the foundation for any low
voltage lighting control system. The BZ-2xx series supplies low
voltage power to occupancy sensors and other control devices,
switching line voltage in response to signals from control devices.
The BZ-2xx series of power packs attaches to existing junction
boxes or mounts into fixture wiring trays.
Low voltage wiring should use at least 22-gauge wire. High voltage
connections should be appropriately sized for the breaker and load.
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 sensors, and other control devices.

INSTALLATION
Installation Notes
1. * Refer to occupancy sensor data sheet to determine
maximum number of sensors. Power pack mA output is
225mA.
2. Power packs should be installed in accordance with state,
local and national electrical codes and requirements.
3. Power packs are designed to attach to existing or new
electrical enclosures with 1/2 inch knockouts.
4. 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.
5. The BZ-2xx is a Class 2 Output Power Supply, suitable for
parallel interconnection of up to 4 units maximum. This power
pack is UL Listed for Interconnection of Power Sources in
accordance with National Electric Code.
NOTE:
The BZ series uses an AC power relay and is not
typically suited for high-impedance DC or dry-contact
applications.
WARNING:
TURN THE POWER OFF AT THE
CIRCUIT BREAKER BEFORE WIRING.
