When the extinguished agent is discharged, the releasing panel activates the purge panel controller. The controller disables the key operated purge switch, lights the Panel Activated indicator and starts the timing cycle.
The purge fans can NOT be activated until the preset “agent soak time” has expired. When the time cycle is complete, the Purge Ready indicator is activated and the Purge switch is enabled.
Operation of the purge switch will light the Purge Running indicator and activate the remote relay output. This 24vdc output is used to energize a Start Relay (relay by others), located at the purge fan(s).
