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.
4. The BZ-150 is a Class 2 Output Power Supply, suitable for parallel
interconnection of up to 10 units maximum. This power pack is UL Listed for
Interconnection of Power Sources in accordance with National Electric Code.
OPERATION
With the BZ-150, the load can be turned ON and OFF automatically using an
occupancy sensor input, a timer, panel or BAS input, and manually from an
optional low voltage momentary switch. Use the Mode Switch to select either the
Auto ON mode, or the Manual ON mode. Remove power from the BZ-150 when
changing the switch setting, or cycle power to it after changing the setting.
Auto ON (Mode Switch LEFT - default)
The occupancy sensor input, Hold ON input and the optional momentary switch
input can all be used turn ON the load.
When the load is turned OFF using the momentary switch, the BZ-150 does not
turn it ON automatically until after the sensor time delay expires (e.g., as might
be required for a presentation). Pressing the momentary switch before the sensor
time delay expires turns ON the load.
When the occupancy sensor's time delay expires, the BZ-150 reverts to Auto ON
mode and it turns ON the load with the next input from the occupancy sensor.
Manual ON (Mode Switch RIGHT)
Occupants must press the low voltage momentary switch to turn ON the load.
When the occupancy sensor is the only input keeping the load ON, the load turns
OFF when the sensor's time delay expires. If the sensor input re-triggers within
30 seconds after the load turns OFF, the load turns ON again. After 30 seconds
expire with no sensor input, press the momentary switch to turn ON the load.
