Fire Suppression System; General Description; Automatic Operation; Manual Operation - Broaster VF-2 Service & Parts Manual

GENERAL DESCRIPTION

The Fire Suppression system is specifically
designed for controlling wet chemical fires
in the fryer.
The system consists of a cylinder assembly
(with pressure switch and gauge), actuating
lever, (2) fusible link assemblies, manual pull
station and two nozzles.

AUTOMATIC OPERATION

Upon the detection of a fire, the system will
automatically operate. The fusible link in the
cooking area separates at a temperature of
280° F, which allows the spring to pull down
on the actuating lever. The valve stem is
pushed down releasing pressure and wet
chemical to the nozzles. If the heat contin-
ues to rise the fusible link in the fan com-
partment separates and allows the fire
damper to drop to prevent any flames, if
present, from exiting the cabinet.

MANUAL OPERATION

When the manual pull handle on the front
panel is pulled, the system operates simi-
larly by disconnecting the fusible link cable
from the actuating lever. The spring pulls
down on the lever releasing pressure and
wet chemical to the nozzles.
