FP 400Y-7BM
The BERMAD Model FP 400Y 7BM is an elastomeric deluge valve, 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-7BM 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.
An anti-flooding feature is provided by using an in-line check valve, which creates an intermediate vented chamber using a Normally Open drip-check.
As an option the 400Y 7BM features a visual quarter turn valve position indicator, available with limit switches for remote valve position monitoring.

System Installation
A typical installation of the BERMAD model 400Y-7BM features automatic actuation via a solenoid valve and crosszone releasing control panel.
Actuation occurs only when the control panel receives simultaneous electric signals from an electric fire-detection system and a low pressure sensing switch/relay valve.
When fitted with a limit switch, the valve can send a feedback signal to the remote valve position monitoring system.
An inline check valve and drip-check valve create an intermediate vented chamber to ensure against flooding when the valve is closed.
