Operation
The BERMAD Model PC11-FP-400E-3D is suitable for systems that include electric fire detection and a piping system with a wide variety of open nozzles. In the SET position, the line-pressure, which is supplied to both the main valve’s control chamber [1] and a Hydraulic Relay Valve (HRV-2) [2], through the priming line [3], a Check Valve [4], an Accelerator [5] with priming restriction and a 3-Way Solenoid [6], is trapped by the Check Valve, by the closed HRV-2, and by a closed Manual Emergency Release [7]. The trapped pressure holds the main valve’s diaphragm and plug against the valve seat [8], sealing it drip-tight and keeping the system piping dry. The HRV-2 is held closed by the line-pressure through the solenoid. Under FIRE or TEST conditions, an electric detection system working through a control panel, triggers the solenoid to open the HRV-2, causing water to exit through the Accelerator faster than it can be supplied. Pressure is then released from the main valve control chamber by the opened HRV-2 or the Manual Emergency Release, allowing the main valve to open and water to flow into the system piping and to the alarm device (if mounted).
