3. The agent reacts with hot grease forming a soap -like
layer (saponification) that helps prevent the escape of
combustible vapors, thus preventing re- ignition.

• required upon system actuation. It is recommended that
make up or supply air fans, integral to the exhaust hood(s)
being protected, should be shut down upon system actua-
tion. Exhaust fan(s) in the ventilation system should remain
on during system discharge as they assist the dispersion of
chemical through the ventilating system. The system. is UL
Listed with or without exhaust fan shutdown. •
The KITCHEN KNIGHT II and the KITCHEN KNIGHT
Restaurant Fire Suppression System are compatible as long
as separate installation guidelines are followed per each
•
system design manual. Exception: The actuation limitations
for the KITCHEN KNIGHT II system may be utilized for the
•
KITCHEN KNIGHT system. Also, control heads, prior to
Model No. 3, may be utilized on KITCHEN KNIGHT II
systems, provided that the limitations used with those
control heads are followed.
