RSPC-ESP FIRE MODE
TESTING INTERNAL FIRE MODE
The internal fire protection system may be tested periodi-
cally by pushing and holding for 20 seconds, the “Fire Test
Switch” located inside the electrical compartment of the
control cabinet. Pushing this switch duplicates thermostatic
action. CAUTION: Before pushing the “Fire Test Switch” ,
check to see if the internal fire protection system is tied to
the building alarm system.
TO RESUME NORMAL OPERATION
1. To discontinue the 2 minute cool down cycle at any
point during the cycle, push the
“Exit”
F5 button on
the C-6000 Command Center.
2. Push the “Start Fan” F1 button on the Command
Center.
SURFACE FIRE PROTECTION
The National Fire Protection Association, NFPA-96 docu-
ment requires fire extinguishing equipment over all grease
producing cooking equipment such as griddles, ranges,
fryers, broilers, and woks. In addition, the system must
protect the interior of the ventilator and the exhaust duct.
The most common fire system is a wet chemical type. In the
event of a fire this system would normally be activated and
discharged prior to the ventilator’s internal fire protection.
If the fire is unusually severe or the surface fire protection
system malfunctions, the ventilator’s internal fire protection
system would activate, thus providing a second level of
defense. These systems may be intertied with the ventilator
control cabinet to activate the External Fire Mode.

EXTERNAL FIRE MODE
An External Fire Mode is activated by the Pollution Control
Units or Ventilator’s Fire Suppression (Duct, Plenum, Sur-
face/Appliance) system’s microswitch or contacts and/or an
optional break glass fire switch (see Figure 5). Terminals
4 & FS are used for the External Fire Mode, refer to wiring
diagram for details. The break glass fire switch, if used,
would normally be located at the exit of the kitchen. When
the External Fire Mode is activated, the following occurs:
1. The Exhaust Fan comes on immediately if it was off to
help remove smoke, heat, etc.
2. The Supply Fan shuts off immediately.
3. The digital display reads “Ext.FireActive” and alternates
between “Reset FireSwitch” and “Fan On, Wash On”.
4. A red light on the Command Center flashes.
5. After a 60-second delay, a fire smothering water spray
is released into the interior of the RSPC-ESP and the
Gaylord CG3 ventilators, if so equipped, through the
spray nozzles.The 60-second delay allows the RSPC-
ESP's and ventilator’s fire suppression system time to
put out the fire, before starting the water spray.
If the fire intensifies and the thermostat reaches 250°F, the
fire damper would then close on a Gaylord CG3 Ventilator,
if so equipped, and the exhaust fan would shut off. See
Internal Fire Mode.
To resume normal operations, open the fire switch and flip
the toggle switch to the position marked “normal”. Replace
the glass rod and close the cover. Push either the “Start
Fan” or “Start Wash” button.
INTERNAL & EXTERNAL FIRE MODES AT THE SAME
TIME
It is possible that both the Internal and External Fire modes
can be activated at the same time. If this occurs, the Inter-
nal Fire Mode will override the External Fire mode until the
thermostat(s) cool below 250°F. At this point the Cool Down
Cycle will start counting down for 2 minutes. After the Cool
Down Cycle, the External Fire mode will start.
Special Note: If the control is in the Cool Down Cycle when
the External Fire mode is activated, the Cool Down Cycle
will finish counting down for 2 minutes, before switching to
the External Fire Mode.
FIRE MODE SUMMARY:
Note: The Damper Position applies to a Gaylord CG3 Ventilator,
if so equipped.
Summary of Both Fire Modes at the Same Time
1. Internal Fire Mode (until thermostat temperature
drops below 250°F)
2. Cool Down Cycle (for 2 minutes)
3. External Fire Mode (until the External Fire Switch
is reset)
