LOW VOLTAGE INPUTS
Four +12-24VDC input wires are provided to control the load relay. The inputs may
be used in combination or individually, depending on the needs of the application.
See the WIRING section for wiring information.
Maintained Inputs:
Control ON
(Blue) – This input is intended for occupancy sensor input.
Applying 12-24VDC closes the relay.
Remove the voltage and the relay opens if no other input is holding it closed.
Hold ON
(Orange) – This input is intended for timer or panel input.
Applying 12-24VDC closes the relay.
Remove the voltage and the relay opens if no other input is holding it closed.
It overrides Control ON input.
Hold OFF
(Brown) – This input is used for timer, panel, BAS or load shed input.
Applying 12-24VDC opens the relay.
Remove the voltage and the relay can accept any other input.
It overrides Control ON and Hold ON inputs.
Momentary Input:
Manual ON/OFF
(Grey) – This
input is for a low voltage
momentary switch. Applying
12-24VDC momentary input
changes the relay to the
opposite state.
It overrides Control ON, Hold
ON and Hold OFF inputs.
BI-LEVEL CONTROL
WITH MANUAL ON
The diagram to the right shows
how to confi gure BZ-150s to
provide bi-level lighting control
with both Automatic ON and
Manual ON features.
As shown, upon occupancy
detection load A turns ON
automatically. To turn ON load B
the user must press momentary
switch B. Both loads turn OFF
automatically when the sensor
time delay expires, or manually
using switch A and B.
