Pre-Action in Elevator Technical Room

This animation presents the BERMAD Pre-Action fire protection system, which is installed at the machine room as an integral component of the building’s fire protection system.

Double Interlock Pre-action BC-400E-7BM-UL

BERMAD double-interlock, pre-action, electric-electric release fire protection system for buildings is designed for use in sensitive or valuable properties where accidental activation may cause substantial water damage.
The BC-400E-WBF-7BM-UL system controls dry pipe sprinklers that include an electric fire detection unit and an electric supervised device for detecting low piping air pressure.

The system admits water into the sprinkler piping only when both the fire detection unit and the low air pressure device simultaneously signal the control panel to trigger the solenoid valve.

  • Compact structure with small footprint specially designed for vertical installation in tight and confined spaces such as water cabinets and technical floors
  • Integral factory assembled unit – easy and simple installation reduce assembly errors and logistics difficulties
  • Factory calibrated and adjustable on site, saving time and reducing engineering, operating and inspection workloads
  • Hydraulic latch open – patented “easy lock” closes only upon local manual reset
  • Drip check and leak control – visual and electrical indication of leaking valve
  • In-line check valve – intermediate vented chamber provides anti-flood protection
  • High quality construction materials ensure reliable long lasting operation
  • Fully supported and balanced rolling diaphragm – low actuation pressure and excellent low flow regulation performance
  • Immediate valve response – ensures operation after long standby periods; specially designed for fire protection systems
  • Integral drain port – external drain valves not required

Typical Application

  • Controlling sprinkler systems in spaces sensitive to accidental water damage in buildings such as libraries, museums, archives and even private homes
  • Controlling sprinkler systems in critical areas such as technical floors, computer and electronics rooms, telecommunications equipment, transformer rooms and other similar facilities where accidental water release can cause a significant damage
  • Controlling sprinkler systems installed under freezing conditions and in cold storage facilities where fire protection pipelines are kept empty while not in use
