Double Interlock Pre-action System Electric-Pneumatic Release
The BERMAD model 400Y-7DM utilizes an elastomeric deluge valve, designed specifically for advanced fire protection systems and the latest industry standards.
Electric-Pneumatic Double interlock systems include automatic sprinklers attached to a supervised dry sprinkler piping system and a supplementary electric detection system.
The 400Y-7DM admits water into the sprinkler system piping only when both the electric detection device and the pneumatic supervised systems are simultaneously activated.
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-7DM features a quarter turn valve position indicator available with limit switches for remote valve position monitoring.
