1. Switch on the mains voltage.
The state display of the lintel-mounted smoke switch lights up green.
2. Remove the dust protection film or dust protection cap from the housing of the hold-open system so that
the smoke openings are clear.
3. Remove the protective covers from the ceiling-mounted detectors.
6.1 Check the self-closing characteristic of the door
6.1.1 1-leaf door
1. Open the door leaf completely. The door leaf is held in the open position by the hold-open system.
2. Activate the test button on the lintel-mounted smoke switch. The state display lights up yellow for approx.
4 s. The door leaf closes and snaps into the latch.
3. If necessary, adjust the manual disengaging torque in the opened position:
Open the door leaf completely. According to EN 1155, the disengaging torque should be between 40 Nm
and 120 Nm at an opening angle of 90°.
6.1.2 2-leaf door
1. Open both door leaves completely. The door leaves are held in the open position by the hold-open system.
2. Activate the test button on the lintel-mounted smoke switch. The state display lights up yellow for approx.
4 s. The door leaves close, following the closing sequence. Both door leaves close completely and the active
leaf snaps into the latch.
3. If necessary, adjust the manual disengaging torque in the opened position:
Open both door leaves completely. According to EN 1155, the disengaging torque should be between 40 Nm
and 120 Nm at an opening angle of 90°.
4. Push the active leaf out of the hold-open function by hand, the passive leaf closes automatically. The active
leaf comes to a standstill and then closes when the passive leaf is closed.
6.2 Testing the smoke detectors
Test aerosol, ID 059168
Systems may only be tested with an aerosol that evaporates without leaving any residue.
6.2.1 GC 151
Carry out the following steps within approx. 2 minutes:
1. Press the test button, the state display changes from green to yellow.
Wait until the state display lights up green again.
2. Open the door leaf completely. The door leaf is held in the open
position by the hold-open system.
3. Now spray the test aerosol from a distance of about 15 cm into
the free smoke opening in short bursts lasting about 1 s with 1 s
between bursts, covering the upper smoke opening of the smoke
detector for this.
The smoke detector must trigger (change of the state display from
green to red). The door closes.
Fig. 6.2.1.1
6.2.2 GC 152, ORS 142 and GC 172
1. Open the door leaf completely. The door leaf is held in the open position by the hold-open system.
2. Spray the test aerosol from a distance of 10 cm to 15 cm into the free smoke opening in short bursts lasting
about 1 s with 10 s between bursts.
The smoke detector must trigger (change of the state display of the lintel-mounted smoke detector from
green to red). The door closes.
6.3 Testing the thermal detectors GC 153 and GC 173
1. Open both door leaves completely. The door leaves are held in the open position by the hold-open system.
2. Test the thermal detector GC 153 using a tester for heat detectors.
The thermal detector must trigger (change of the state display of the lintel-mounted smoke detector from
green to red). The door closes. The test can also be carried out using a hair dryer. The air flow must reach
a temperature of at least 60 °C but must not exceed 90 °C.
