When the extinguished agent is discharged, the
releasing panel activates the purge panel con-
troller. 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 indica-
tor 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).
