Fire Alarm Sequence; After Actuation - Accurex XRRS Installation, Operation And Maintenance Manual

Fire Alarm Sequence

A fire alarm sequence will only occur upon the detection
of extremely high hood temperatures (approximately
216°), or when the remote pull station is pulled (if
provided).
The fire alarm sequence causes:
1. Audible alarm
2. Fire system (wet chemical) discharge
3. Fuel shut off to disconnect fuel to the cooking
appliance (if not already shut off due to a high
temperature alarm).
NOTE
The fire alarm sequence can only occur when the fire
suppression control board is running in fire detect
mode.
NOTE
To mute the audible alarm, place the hood into
service position, and press "RESET" button on fire
suppression control board.

After Actuation

NOTE
A complete system inspection and servicing must be
done immediately following a kitchen range top fire.
Consult an authorized fire equipment company for
service or proper procedure.
NOTE
All service on the fire suppression system after
actuation should be performed by authorized
equipment distributor.
