Construction
The BERMAD model 400E-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 400E-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.
