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.

Hydraulically Controlled Deluge Valve BC-400E-1M-UL

BERMAD’s hydraulically controlled deluge fire protection system for buildings is designed for use in systems that include wet pilot lines with closed fusible plugs (thermal releases) and piping with wide variety of open nozzles. The wet pilot lines are installed along the area protected
by the main system. This deluge system is capable of delivering large quantities of water over a large area in a relatively short period of time.
BERMAD’s deluge valves are specially designed to open fast and smoothly while preventing water hammer. The BC-400E-1M-UL system controls open nozzles sprinklers; this UL-Listed system admits water into the sprinkler piping when the pressure in the pilot line drops due to a thermal release or manual operation.

  • Compact structure – vertically installed small footprint specially designed for tight and confined areas such as water cabinets and technical floors
  • Integral factory assembled unit – easy and simple installation reducing assembly errors and logistics difficulties
  • Factory calibrated and on site adjustable – saving time and reducing engineering, operating and inspecting workloads
  • Hydraulic latch open – patented “easy lock” that closes only upon local manual reset
  • Drip check and Leaks control – visual and electrical indication for leaking valve
  • High quality construction materials ensure reliable long lasting operation
  • Full bore valve port area and hydrodynamic body provide unobstructed flow path, with minimal pressure loss and low cavitation damage
  • 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 open nozzles sprinkler systems in buildings, parking areas, warehouses, workshops, water curtains, central gas repositories, etc.
  • In installations where electricity is not available or where hydraulic control operation is preferred.
  • In buildings separated to several fire zones using a common water source, where false tripping of the system should be eliminated.
  • In deluge fire protection systems that require UL approval.
