Double Interlock Pre-action System Electric-Electric Release with Pressure Control
The BERMAD Model FP 400Y 7BC utilizes an elastomeric deluge valve with a unique Vulcanized Radial Seal Disk (VRSD) technology, designed for advanced fire protection systems and the latest industry standards.
The Double Interlock Pre‑Action is suitable for use in systems requiring that water be kept out of the sprinkler piping until two fire detection devices have simultaneously reacted.
The FP-400Y-7BC Pre-Action valve admits water into the sprinkler piping only when both the detection device and loss of system pneumatic pressure simultaneously signal the control panel to trigger the solenoid valve.
An integral pressure reducing pilot valve ensures a stable and precise preset downstream system water pressure.
