Resetting Outputs
Should any of the solid state
outputs shut off due to a fault
condition, the output will need to
be reset. A diagnostic check should
be conducted prior to a reset.
Resetting can be done in three
different ways:
• Through the SoundOff Central
bluePRINT Software
• By pressing the reset button
shown at the top right of the
board
• By connecting the programmed
reset wire to ground typically
with a user supplied momentary switch. This function can be
programmed to any input, using SoundOff Central bluePRINT.
Diagnostic Status LED Lights (Control Panel)
The control panel can also indicate additional system faults, as
detailed in the below table.
