OFFICE COPY .. r IVIdbLbI vupy Chapter 1 —General Information Page 1-1 REV. 4 CHAPTER I GENERAL INFORMATION • INTRODUCTION Temperature Limitations The PYRO-CHEM® KITCHEN KNIGHT®II Restaurant Fire The operating temperature range of the PYRO-CHEM Suppression System is of the pre-engineered type as KITCHEN KNIGHT II System is 32° F. (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 UL Listing Grease-Laden Vapors from Commercial Cooking Equipment. The system is designed to provide fire protection for restau The PYRO-CHEM KITCHEN KNIGHT II Restaurant Fire rant cooking appliances, hoods, and ducts. Installation and maintenance of the system must conform to the limitations Suppression System has been tested to the UL Standard for detailed in this manual and be performed by an Authorized Fire Extinguishing Systems For Protection of Restaurant PYRO-CHEM KITCHEN KNIGHT II dealer. 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.

Duct Protection It is not required that the fan be shut down or the exhaust 1/2 W duct be dampered for the system to operate properly. t l All duct protection is UL listed without limitation of maximum duct length (unlimited length).This includes all varieties of 00B172ac ductworks both horizontal and vertical including ducts that .— 1/2 L_. run at angles to the horizontal and ducts with directional bends. 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.The nozzle must then be installed on the centerline of the area it protects and aimed • directly into the duct opening. • ULEX 3830 March 1,2006" Chapter 3—System Design Page 3-2 REV.3 Modularizing Ducts When working with Chart 2, one half of the quantity of nozzles DUCT SIZES GREATER THAN 100 IN.(254 cm) PEfCMETEfi. determined must be equally positioned in the top half of the area of the duct and the remaining half of the nozzles must be • Ducts over 100 in. perimeter must be modularized using positioned in the bottom half of the duct area. 2D nozzles (Part No 551038) Example:The duct to be protected has a Side "A" of 40 in • No round duct option available and a Side"B" of 60 in.
