See Figure 4-1. ances and hood and duct configurations.The design information listed in this section deals with the limitations and parameters of this pre-engineered system. Those individuals responsible for the design of the R-102 system must be trained and hold a 'Pr current ANSUL certificate in an R-102 training program. The R-102 and the PIRANHA systems use compatible agents and components, therefore, they may be used together for cooking appliance, hood, and duct protection. The primary AUTOMAN Release can be either an R-102 or a PIRANHA � AUTOMAN Release and can actuate up to two additional R-102 or PIRANHA Regulated Actuators. In systems utilizing a 101 2-8IN, remote release, any combination of the maximum number of (51-203mm) regulated actuators can be used. • Both systems must actuate simultaneously. • Each system must be designed and installed per its appropri- FIGURE 4-1 ate manual. oi� • Adjacent appliances requiring protection must be protected 2. In installations where a UL listed damper assembly is with the same type of system, either R-102 or PIRANHA, employed, the duct nozzle can be installed beyond the 8 unless the center-to-center spacing between the adjacent in. (203 mm) maximum, to a point just beyond the damper R-102 and PIRANHA nozzles is no less than 36 in. (914 mm). • When appliances are protected with R 102 nozzles, the assembly that will not interfere with the damper. Exceeding hood and connecting duct above those appliances cannot be the maximum of 8 in. (203 mm)in this way will not void the protected with PIRANHA nozzles.
