The MEA Certification No. is 91-99E-Vol. II. temperature. 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. • 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.

This includes all varieties of I CO3172ra ductworks both horizontal and vertical including ducts that /-- 1n rqn at angles to the horizontal and ducts with directional berjds. • L • Duct 'protection requires that a nozzle be positioned to Figure 3 -1a. discharge into the duct: Two nozzles are available for duct protection. The Model IL Nozzle; Part No. 551026, is a one (1) flow , nozzle. A single IL nozzle Is capable of protecting square or rectangular ducts with a• maximum perimeter of 50 in. • (127 cm), with the diagonal being a maximum of 18 3/4 In. (47.6 cm). It can also protect a round duct with a maximum diameter of 16 in, (40:6 cm). The Model 2D duct nozzle, Part No. 551038, is a two (2) flow nozzle. A single 2D nozzle is capable of protecting • square or rectangular ducts with a maximum perimeter of 100 in. (254 cm), with the diagonal being a maximum of • 37 3/8 in. (94.9 cm). It can also protect a round duct with a maximum diameter of 31 7/8 in. (81 cm). • When two (2) 2D duct nozzles are used to protect a single • duct, the cross sectional area of the duct must be divided into two equal symmetrical areas.
