WARNING:

TURN THE POWER OFF AT THE CIRCUIT BREAKER

BEFORE INSTALLING POWER PACKS

ONLY QUALIFIED ELECTRICIANS SHOULD ATTEMPT TO

INSTALL WATT STOPPER POWER PACKS

DESCRIPTION:

The BZ power pack is the foundation for any low voltage

lighting control system. The BZ supplies low voltage power to

occupancy sensors and other control devices, switching line

voltage in response to signals from control devices. The BZ

power pack is attached to existing junction boxes or mounted

into fixture 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 diagram to verify power pack is wired correctly.

Improper wiring can cause damage to power pack, lighting

system, and occupancy sensor.

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. 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.

OPERATION:

Low Voltage Inputs:

Three +5-24VDC maintained inputs are provided with the

following functionality:

1. Control ON (Blue Wire) – Applying 5-24VDC to this input

closes the relay. Remove the voltage and the relay returns

to its normal state. This input is intended for sensor or

control device input

2. Hold ON (Yellow Wire)- Applying 5-24VDC to this input

closes the relay. Remove the voltage and the relay returns

to its normal state. This input is intended for timer or panel

input and overrides the Control ON input.

3. Hold OFF (Brown Wire)- Applying 5-24VDC to this input

opens the relay. Remove the voltage and the relay can

accept input from either the Control On or hold on inputs.

This input is intended for timer, panel input, or load shed

signals and overrides the Control ON/Hold ON signal input.

CAUTION:

CONNECT ONLY THE POWER SUPPLY WIRE FOR VOLTAGE

USED. INSULATE/CAP UNUSED POWER SUPPLY WIRE

Over Current Protection:

If the current drawn from the BZ exceeds 150mA (i.e. there are

too many sensors per power pack) the +24VDC output will be

turned off. The LED will continuously blink to indicate that the

Over Current Mode has been activated. Upon removal of fault

condition, the BZ will not attempt to restore the power for 10

seconds after an over-current event. This protection also

applies if the low voltage outputs are shorted.

LED Indicator:

The LED will indicate when the load is active with a continuous

red light and will indicate when the current limit of the BZ has

been exceeded by blinking continuously.
