Vertical sensors strips drum walking area
Co-rotating, vertical sensors, radiating to the floor, are mounted on top of the turnstile wings and/or on
top of the turnstile centre part. They secure the danger zone from approx. 12-20 cm in front of each
turnstile wing to the turnstile centre. When a safety sensor is activated within the danger zone, the
turnstile will switch to slow speed or stop depending on parameterization. Slow speed is maintained
until a horizontal or vertical electric safety strip on the turnstile is activated. Then the turnstile will stop.
When the electric safety strip is no longer activated and no safety sensors are activated, the turnstile
will start and accelerate to the preset walking speed.
4.11
Air curtain control
Direct ventilation to the interior via an air duct built into the doorway.
The air curtain is controlled by a potential-free door contact that triggers once the turnstile starts to ro-
tate.
4.12
Foldable turnstile wings and/or foldable drum walls
The system can be equipped with hinged turnstiles and / or, in case of a three-wing system, with
hinged drum walls.
If a turnstile leaf and/or a drum wall is manually opened, this condition is signaled to the system con-
trol via a monitoring switch. At the same time, the turnstile movement is immediately stopped in all op-
erating modes and the system control is switched off.
To continue the set operating mode, all turnstile leaves and/or the drum walls must be manually re-
engaged in their original position.
The turnstile starts automatically and continues the set operating mode.
Folding turnstile leaves are held in position by electrical or mechanical leaf locks.
Folding drum walls are held in position by magnets.
