LOW VOLTAGE INPUTS
Four 5—30 VDC 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.
Control Inputs:
Control ON
(Blue wire) – This input is intended for occupancy sensor input.
• Applying 5—30 VDC closes the relay in Auto ON Mode.
• Remove the voltage and the relay opens if no other input is holding it closed.
Hold ON
(Orange wire, BZ-250/BZ-250-347 only) – This input is intended for timer
or panel input.
• Applying 5—30 VDC closes the relay in Auto ON Mode.
• Remove the voltage and the relay opens if no other input is holding it closed.
• This overrides Control ON input.
Hold OFF
(Brown wire, BZ-250/BZ-250-347 only) – This input is used for timer,
panel, BAS or load shed input.
• Applying 5—30 VDC opens the relay.
• Remove the voltage and the relay can accept any other input.
• This overrides Control ON and Hold ON inputs.
Momentary Input:
Manual ON/OFF
(Grey wire, BZ-250/BZ-250-347 only) – This input is for a low
voltage momentary switch.
• Applying 5—30 VDC momentary input changes the relay to the opposite state.
• This overrides Control ON, Hold ON and Hold OFF inputs.
