Pre- Action & Dry Pipe
FP 400E-7M - Single Interlock Pre-action, Electric Release System
The BERMAD Model FP 400E-7M Single Interlock Pre-Action Release System is suitable for use in systems requiring that water be kept out of the sprinkler piping until an electric detecting device has been activated. Single Interlock Pre-Action Systems include automatic sprinklers attached to a dry sprinkler piping system, with a supplementary electric detection system installed in the same area. This system admits water into the sprinkler piping upon activation of the detection system.Water is discharged only through sprinklers that have been opened due to excessive heat. When a Supervised System is required, a pneumatic low pressure supply shall be provided. An anti-flooding feature is provided by utilizing an in-line check valve, which creates an intermediate vented chamber using a Normally Open drip-check.

FP 400E-7BM - Double Interlock Pre-action, Electric- Electric Release System
The BERMAD Model FP 400E-7BM Double Interlock Pre-Action, Electric-Electric Release System 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 double interlock systems include automatic sprinklers attached to a dry sprinkler piping system, along with a supplementary electric detection system and an electric Supervised System of low air pressure in the system piping. The Double Interlock 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 utilizing an in-line check valve, which creates an intermediate vented chamber using a Normally Open drip-check.

FP 400E-7DM - Double Interlock Pre-action, Electric- Pneumatic Release System
The BERMAD Model FP 400E-7DM Double Interlock Pre-Action, Electric-Pneumatic Release System 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-Pneumatic Double Interlock Systems include automatic sprinklers attached to a dry sprinkler piping system, with a supplementary Electric Detection System and a Pneumatic Supervised System of low air pressure in the system piping. The Supervised System consists of a Pneumatic Pilot Valve (PORV), and pneumatic low pressure supply. The Double Interlock Pre-Action System admits water into the sprinkler piping only when the detection system triggers the solenoid valve through the control panel, while the PORV is simultaneously activated due to the pressure drop in the Supervised System. An anti-flooding feature is provided by utilizing an in-line check valve, which creates an intermediate vented chamber using a Normally Open drip-check.
