External smoke switch control units

RSZ 7 * Extendable smoke switch control unit for all GEZE hold-open devices

RSZ 7 smoke switch control unit Solution for unfavourable lintel situations that leave too little space above the smoke chambers, for example: The RSZ 7 smoke switch control unit has a telescope function. The smoke detector can be extended, making it possible to bridge overhangs of about 30 mm.
  • Telescopic function for bridging overhangs of up to 30 mm
  • Connection to 230 V power supply and 24 V DC supply of the hold-open device
  • Voltage supply of the hold-open system is interrupted in the case of an alarm and the doors close
  • Integrated smoke switch with automatic adaption of the alarm threshold
  • Compensates for light contamination of the smoke chamber and thus increases the service life
  • Visual display of the current control unit status
