INTERNAL FIRE MODE
Automatic internal fire protection is accomplished by the ac-
tion of the thermostat(s), which is located in the filter section
of the RSPC-ESP. When the temperature of the conveying
airstream, which must pass over the thermostats, reaches
250°F, the system is activated, and the following occurs:
1. The damper begins closing back to the fire position, on
a Gaylord CG3 ventilator, if so equipped, position 3 as
shown in Fig.4—stopping the combustion-supporting,
natural draft through the ventilator and creating a fire
barrier to contain the fire in the kitchen.
2. The exhaust fan is shut off. The supply fan is also shut
off.
3. Fire-smothering water spray is released into the interior
of the RSPC-ESP through the spray nozzles.
4. The digital display reads "Fire In Hood, Fan Off, Wash
On" for approximately 5 seconds.
5. Then the digital display reads "Fire In Hood, Damper
Closing" for approximately 5 seconds.
6. Then the digital display reads "Fire In Hood, Notify Fire
Department". This display stays on until the thermostat
cools down below 250°F.

CAUTION:
In case of severe fire the thermostats located in the filter
section will activate. As a precautionary measure, it is rec-
ommended that the thermostats be replaced.
FIRE CYCLE
7. A red light on the Command Center illuminates.
8. If the Command Center is intertied with a building alarm
or monitoring system, a fire signal would be sent to that
system.
9. Upon cooling of the thermostat below 250
o
F, the Cool
Down Cycle starts. The water continues to spray during
the Cool Down Cycle (2 minutes). The damper moves
to the exhaust position, on a Gaylord CG3 Ventilator,
if so equipped.
10. While in the cool down cycle the digital display reads
"Cool Down Cycle, xxx sec. to end". xxx is the count-
down in seconds until the wash turns off.
11. At the end of the cool down cycle the water turns off and
the digital display reads "Fan Off 12:00 (actual time),
Start Fan>F1". The damper closes to the wash position
in a Gaylord CG3 Ventilator, if so equipped.
NOTE: The water may be shut off prior to the end of the 2
minute cool down cycle by pushing the “Exit” button on
the C-6000 Command Center. After the water has shut
off, the damper remains in the wash position on a Gaylord
CG3 Ventilator, if so equipped, until the “Start Fan” button
is pushed.
