Product information "Staircase set EM/2 - Chain drive"

smoke extraction system

SHEV systems keep escape routes reliably low in smoke, enable fast and safe evacuation in the event of fire and support the fire brigade in extinguishing work. SHEV systems are also suitable for natural ventilation and can be integrated seamlessly and efficiently into building management systems.

The set includes the following components:

  • 24 V drive with standard brackets
  • RWA control unit
  • RWA control panel
  • smoke detectors

24 V chain drive EM/2

With 300 N compressive and tensile force, the EM is our universal drive for applications in the medium power range. The slim housing is particularly suitable for applications with limited mounting space. The linear shape adapts inconspicuously to the profile.
