The BERMAD Model FP 400E-3D is suitable for systems that include electric fire detection and piping systems with a wide variety of open nozzles. Being pneumatically controlled, the Model FP 400E-3D is recommended for those cases, such as seawater installations, where it is advantageous to keep the solenoid dry. In the SET position the line-pressure, which is supplied to the main valve’s control chamber through the priming line , a Check Valve, and an Accelerator with priming restriction, is trapped by the Check Valve, by a closed Pneumatic Pressure Operated Relief Valve (PORV) and a closed Manual Emergency Release.

The trapped pressure holds the main valve’s diaphragm and plug against the valve seat, sealing it drip-tight and keeping the system piping dry. The PORV is held closed by the dry pilot line pneumatic pressure through the Solenoid. Under FIRE or TEST conditions, a dry pilot line pneumatic pressure drop, or an electric signal that triggers the Solenoid, opens the PORV causing water to exit through the Accelerator faster than it can be supplied. Pressure is then released from the main valve’s control chamber through the opened PORV or the Manual Emergency Release, allowing the main valve to fully open, and water to flow into the system piping and to the alarm device (if mounted).
