(0° C.) minimum to defined by NFPA-17A Standard for Wet Chemical 120° F. (49° C.) maximum. Extinguishing Systems and NFPA-96 Standard for the Installation of Equipment for the Removal of Smoke and Grease-Laden Vapors from Commercial Cooking Equipment.

Cooking Areas. UL300 and Listed by Underwriters Laboratories, Inc. The PYRO-CHEM KITCHEN KNIGHT II System utilizes a wet chemical agent specifically designed to suppress restau- ULC Listing rant cooking area fires.The system provides automatic actu- ation and can be manually actuated through a remote The PYRO-CHEM KITCHEN KNIGHT II Restaurant Fire mechanical pull station. Upon actuation, the system Suppression System is listed by Underwriters Laboratories discharges a pre-determined amount of agent to the duct, of Canada (ULC).The ULC Listing No. is CEX812. plenum, and cooking appliances.The agent acts to suppress fires in three ways: MEA Approval 1. The chemical chain reaction causing combustion is inter- rupted by both the agent itself and the resulting steam The PYRO-CHEM KITCHEN KNIGHT II Restaurant Fire formation. Suppression System has been approved for use by MEA (Material and Equipment Acceptance Division)for New York 2. The agent cools the fire bringing it below auto-ignition City.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. ► ULEX 3830 March 1,2006 CHAPTER U Chapter 2 CompyteVnts 4 Page'2=.1 RE r-� COMPONENTS CYLINDERS &VALVE The PYRO-CHEM KITCHEN KNIGHT II System has available four different size cylinders:Models PCL-160 (P/N 553163), kN��N,oW �;��N 0 PCL-300(P/N 551194), PCL-460 (P/N 551193), and PCL-600 0 'OM!, 4 0 (P/N 551196).Cylinder sizes are expressed in terms of extin- 0 e ■ '® O p guishing agent capacity(i.e.,the PCL-300 uses 3.0 gallons © � __! 0 ® m (11.4 L) of extinguishing agent).The cylinder is manufactured, / N�/ ®COs ,:,,\\\\ 1/21N tested, and meets DOT requirements.Cylinders come pre filled v m \,®g �_ ® "PT with extinguishing agent and are charged with dry nitrogen to a �� i �® /iii, I \:w®.di:, ..., pressure of 225 psig CO 70° F(15.5 bar @ 21 °C).Cylinder ; /11,, \ a'�®//.�� and valve assembly dimensions are shown in Figure 2-1a. ��/®+j jw j .0 % te. b . /, _ Figure 2-1b.Wet Valve Cross Section.
