Fire System Integration
A dedicated fire system microswitch needs to be wired
into the KFCC. During a fire, this will disengage supply
starters, and therefore turn off corresponding supply
fans. If KFCC is configured with “Exhaust in Fire”
option, the KFCC will also engage the exhaust starters,
therefore turning on exhaust fans in the event of a fire.
Dedicated Fire System Microswitch
• Common to terminal C1
• Normally-closed to terminal NC1
• Normally-open to terminal NO1
NOTE
Relay contacts will be dry unless otherwise noted on
the panel’s specific wiring diagram.
Do not use additional relay contacts for power
interruption to appliances. Contacts are rated up to
250 VAC and 8 amps maximum.
Spare Fire Relay
The KFCC includes additional fire relay contacts
standard for shunt trips, alarms, or additional utilities
that need control signals to be sent in the event of a
kitchen fire. The additional relay’s state will only be
changed if the dedicated fire system is wired into the
KFCC. Wiring from added relays to terminals will be
done in the factory.

Switches (Optional)
A switch panel may be supplied to operate lights, fans,
heating/cooling capabilities of a tempered supply, a
damper, or another component of the kitchen exhaust
system. If selected, the switch(es) will be provided one
of four ways:
1. Shipped loose for remote mounting
2. Mounted on the hood
3. Mounted on the hood utility cabinet
4. Mounted on a wall utility cabinet
If the switches and the KFCC are both mounted on the
same hood, wiring to the fan switches will be done in
the factory.
