The agent reacts with hot grease forming a soap -like layer (saponification) that helps prevent the escape of combustible vapors, thus preventing re- ignition. The shutdown of all sources of fuel and electric power that produce heat to all equipment protected by the system is • 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.
