Description

TRIMPAC® Model B-3 & B-3B is a factory assembled trim package for a single interlocked preaction system with electric release module in a metal enclosure. The standard trim normally required on a deluge valve has been moved to a single cabinet. TRIMPAC® Model B-3 & B-3B provides access doors for the emergency release (B.1) and alarm test valve (B.7) for manual operation of these trim valves. TRIMPAC® Model B-3 & B-3B is equipped with priming water pressure and water supply gauge view-ports for easy monitoring of water pressures. TRIMPAC® Model B-3 & B-3B eliminates the installation of alarm trim piping and release trim piping at the deluge valve. The enclosure protects trim valves from inadvertent operation. The included stainless steel hoses (or field provided hard piping) from the valve body to the enclosure assembly allows the assembly to be installed remote of the sprinkler system riser. TRIMPAC® Model B-3 & B-3B can be utilized for systems regardless of valve size. A valve drain package for the deluge valve is required and is ordered based on the deluge valve size.
