Double Interlock Pre-action System Electric-Electric Release with Pressure Control

FP-400Y-7BC

400Y Series

Fire Protection

The BERMAD Model FP 400Y 7BC utilizes an elastomeric deluge valve with 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 an electric detecting device and a sprinkler have both been activated.
Electric-Electric double interlock systems include automatic sprinklers attached to a dry sprinkler piping system with a low air pressure switch, along with a supplementary electric detection system which are both wired to a Cross-Zone releasing control panel.
Model FP 400Y-7BC Pre-Action System admits water into the sprinkler piping only when both the detection device and the supervised systems simultaneously signal the control panel to trigger the solenoid valve.
The FP-400Y-7BC using the integral pressure control pilot will maintain a stable set downstream pressure.
