Key features

  • Electromagnetic holder keeps the fire door/damper in the open position
  • In the event of a power failure or a signal from the fire alarm system, it immediately releases the door to close automatically
  • 3 sizes depending on door weight and size: 650 / 1,300 / 2,000 N
  • 24 V DC power supply, low power consumption (~1–3.7 W depending on model)
  • Requires a separate armature plate (GH-6 or GH-13/20) and an external Ex-e terminal box
  • Steel/plastic (polycarbonate) housing, IP65 protection rating
  • ~1 m halogen-free and silicone-free cable (5 m / 15 m variants on request)

Applications

Fire doors Fire gates Smoke-tight closures Escape routes

Designation key

What the ExMag model designation means

EXM-650 / 1300 / 2000

Number in the designation = holding force directly in newtons (N) – no conversion or adjustment needed.

GH-6 / GH-13/20

Armature plate on the door side – selected according to the magnet force, not included in the delivery of the magnet itself.
