Lights Out In Fire; Additional Fire Contacts; Additional Exhaust Contacts - Greenheck KFCC Installation, Operation And Maintenance Manual

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 8
or Combination Light/Fan Switch on page 9 for
additional wiring information.
NOTE
For lights out in fire option, light circuit must not
exceed 900W maximum.
Additional Fire Contacts (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 at the
factory.
