GEZE smoke switch control unit RSZ 6
Smoke switch and power supply for all GEZE hold-open mechanisms

The GEZE smoke switch control unit RSZ 6 in the typical GEZE design has an overall height of 30 mm. It is connected to the 230 V power supply system and supplies the connected hold-open mechanisms reliably with 24 V DC voltage (max. 200 mA).

The smoke switch control unit is mounted on the vertical wall above the door opening, thus making the early detection of fire and smoke possible (please keep at least 20 mm clear of the ceiling). If an alarm is triggered, the voltage supply to the hold-open mechanisms (e.g. electrical hold-open device in the guide rail or holding magnet) is interrupted and the doors close immediately.

The connection of two additional ceiling-mounted alarms may be necessary depending on requirements. The integrated smoke switch has an automatic adaptation of the alarm threshold. This compensates light soiling of the smoke chamber and increases service life. The current state of the smoke switch is shown by an optical signal.
