Lights Out In Fire (Optional)
This option will turn off the kitchen hood lights in
the event of a fire without the use of a shunt trip
breaker. If provided, this option will be factory wired.
Normal light circuit wiring should be followed. Please
see either Switches (Optional), Lights on page 7
or Combination Light/Fan Switch on page 8 for
additional wiring information.
NOTE
For lights out in fire option, light circuit must not
exceed 900W maximum.
NOTE
Relay contacts will be dry. Power will need to be
provided to the common terminal on each set.
Do not use additional relay contacts for power
interruption to appliances. Contacts are rated up to
250 VAC and 8 amps maximum.
Extra Fire Relay (Optional)
The KFCC can include additional fire relays for shunt
trips, alarms, or additional utilities that need control

additional relay’s state will only be changed if the
dedicated fire system is wired into the KFCC. Wiring
from additional relays to terminals will be done in the
factory.
