TRIMPAC® Model D-1 & D-1B SureFire® Single Interlocked Preaction

Viking valve and system offerings provide customers with industry-leading quality that lasts — making the choice to select a Viking valve and system product, such as TRIMPAC® Model D-1 & D-1B SureFire® Single Interlocked Preaction, easier than ever!! 

The Model D-1 and D-1B used with either a Model E or F Deluge Valve (A.1), a Viking Easy Riser check valve (F.1), a PAR-3 or VFR400 Release Control Panel (G.1) and all associated trim piping form a unique operating system. The system piping is normally dry and pnuematically pressurized to supervise the integrity of the piping, fitting and sprinklers and provide the failsafe operation of the system upon loss of the primary and secondary power supplies. Preaction systems are commonly used to help minimize accidential water damage and still provide fast water discharge during a fire emergency. The Viking SUREFIRE® Single Interlock Preaction TRIMPAC® Model D-1 & D-1B is a factory assembled and tested unit. The enclosure incorporates access doors for the emergency release (B.1) and alarm test valves (B.7) and view ports for the prime and water supply pressure gauges (B.9).
