TRIMPAC® Model B-9 and B-9B is a factory-assembled galvanized trim package for a non-interlocked preaction system with an electric release in a metal enclosure with a monitored or non-monitored release solenoid. The standard trim normally required on a deluge valve has been moved to a single cabinet. TRIMPAC® Model B-9 and B-9B 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-9 and B-9B provides access doors for the emergency release and alarm test valve for manual operation. This model is also equipped with priming water pressure and water supply gauge view-ports for easy monitoring of water pressures, and with a monitored solenoid (NC) and a non-monitored solenoid (NC). TRIMPAC® Model B-9 and B-9B 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-9 and B-9B 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.
