Description
TRIMPAC® Model B-11 LPCB Type 1 is a factory assembled trim package for a single interlocked preaction system with electric release module in a metal enclosure. The system piping is pneumatically pressurized for supervisory purposes only. This feature serves to prevent undetected leaks. If the system piping or a sprinkler is damaged, supervisory pressure is reduced and a “low air” alarm is activated. The standard trim normally required on a deluge valve has been moved to a single cabinet.
