OPERATION
Control From Inputs
With the BZ-200, BZ-250, and BZ-250-347, the load can be turned
ON
and
OFF
automatically using an occupancy sensor input. The
BZ-250 and BZ-250-347 provide additional functionality allowing for low voltage input control from a timer, panel, or BAS input, and
manually from an optional low voltage momentary switch. See the section on Low Voltage Inputs for details.
Auto ON/Manual ON Slide Switch (BZ-250/BZ-250-347 only)
Use the Mode Switch to select either the
Auto ON
mode, or the
Manual ON
mode. The mode will take effect within two seconds.
Auto ON (Mode Switch UP - default)
The occupancy sensor input, Hold
ON
input, and the optional momentary switch input can all be used to turn
ON
the load.
When the load is turned
OFF
using the momentary switch, the BZ-250 and BZ-250-347 do not turn it
ON
automatically until after the
sensor time delay expires. However, pressing the momentary switch before the sensor time delay expires will turn the load
ON
.
When the occupancy sensor’s time delay expires, the BZ-250 and BZ-250-347 revert to
Auto ON
mode and turn the load
ON
with the
next input from the occupancy sensor.
Manual ON (Mode Switch DOWN)
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 the load
ON
.
Local Manual Override Push Button
Press the button to manually toggle the power pack relay
ON
and
OFF
.
Power Loss Mode (BZ-250/BZ-250-347 only)
In the event of a power loss, this determines whether the loads will turn
ON
, turn
OFF
, or return to their previous state when power is
restored. To set this, press and hold the Local Manual Override Push Button for the amount of time shown in the following table.
