June 2011 Section 1 General Information Page 1 - 2 Amerex Restaurant Fire Suppression System (EX 4658) GENERAL INFORMATION —ZONE DEFENSE SYSTEM The Amerex ZD Series Pre-Engineered System consists of mechanical and electrical components to be installed by an Authorized Factory Trained and Certified Amerex Restaurant Fire Suppression Systems distributor. The system is composed of an Agent Cylinder Assembly charged with Amerex Kitchen Wet Chemical Agent and a Pneumatic Release Module (PRM) or an MRM, MRM II using a linear link detection network. The system operates either automatically, if actuated by a rupture in the pressurized thermal responsive tubing or by the separation of a thermal link or manually if actuated by a manual pull station. Upon system operation, energy sources for the cooking appliances are required to be shut-off immediately. Electrical shutdown devices or suitable gas valves are referenced in this manual. Other equipment such as audible/visual signaling devices can be added where required. The Amerex ZD and KP Series Systems use the same components and share the same UL Listings and limits for the protection of the exhaust duct, plenum and dedicated appliance protection. They do not share the same piping limitations or installation philosophy. This manual provides the unique limitations which apply to a Zone Defense Fire Suppression System. What is the basic difference between a KP and ZD System Philosophy? The Amerex Zone Defense System was developed for the kitchen that changes out it's cooking appliances frequently to accommodate the change in menu or cooks. The ZD System provides a detection system and protection system which allows for the moving and rearranging of appliances without changing the fire suppression piping or detection device locations. This is accomplished by using a detection network that will detect a fire no matter where it occurs under the hood and will extinguish cooking appliances located anywhere under the hood, as long as they are inside the "Zone of Protection". Also the appliances must be capable of being extinguished from overhead. Appliances such as upright broilers, salamanders, covered tilting skillets, chain feed pizza ovens, etc. are all appliances that cannot be extinguished from overhead, but require specific nozzles with specific aiming for the individual appliance. The use of a "back shelf" over appliances also will block the application of agent from overhead nozzles and therefore requires the use of "Dedicated Appliance Protection" for an appliance with a back shelf. The Amerex Kitchen Protection Fire Suppression System differs from the ZD System in the manner in which it protects appliances and detects a fire under the hood. The KP System uses individual "Dedicated Appliance Protection" for each appliance under the hood requiring protection. A choice of the fire detection method may be a standard thermal link network or one of the two linear detection networks. (PRM or Linear Fusible Link). The KP & ZD Series Systems have their distinct application use in the field of kitchen protection. They both provide superior protection from the hazards of commercial cooking.
