RSZ 7 Extendable smoke switch control unit for all GEZE hold-open devices
- 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
Application Areas
- Approved for all GEZE hold-open devices for the early detection of fire and smoke
- Difficult lintel situations, for example with too little space above the smoke chamber
- Installation above the active leaf on the vertical wall
- Installation possible with surface-mounted line-feed
