DIP SWITCH SETTINGS (Black = switch tab)
DIP switches 1.2.3 set a delay time between shutdown (VFC) and subsequent
extinguisher automatic activation. Delay can be set 0 to 30 seconds in 5 second steps.
Manual only mode can be set with ON.ON.ON.OPT
DIP switch 4 defines critical alarm OPTion.
The default setting is OFF which requires 2 loops to be in alarm (OPT=“double knock”)
before shutdown and time delayed extinguisher activation.
Moving to ON position requires only one loop to be in alarm (OPT=“single knock”)
before shutdown and time delayed extinguisher activation.
Note that the unit dispenses activation delay following depowering of ignition input.
The instant mode is indicated by flashing green PWR LED which gives double flash
whilst moving through the delay and single flash on reaching zero delay instant mode.
