Spare Fire Contacts

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.

system. If selected, the switch(es) will be provided one
of four ways:
1. Shipped loose for remote mounting
2. Mounted on the hood

If the switches and the KFCC are both mounted on the
same hood, wiring to the fan switches will be done in
the factory.
