Safety Features 
Standard Operation 
When a person approaches the revolving door they are detected by the Motion Detectors and the door begins to revolve at a speed of approx. 4 r.p.m. (adjustable).  After a preset time the system switches to the idling speed of approx. 1 r.p.m. and then stops at the X-Position.  (each person approaching will reset timer) 

Safety Devices 
1) Emergency stop button: 
The revolving door can be stopped at any time by pressing the EMERGENCY STOP button located on two corner posts. 

2) Safety Sensor: 
The electrical safety units are mounted in ceiling by the entry and exit.  They are activated when the revolving door wings are approx. 50 cm (20") from the corner post.  If beam is broken be a late entering pedestrian the rotation will stop immediately. 

3) Handicapped Person Button: 
Unsure or handicapped persons, for whom the walking speed appears too fast, can operate the handicapped button.  The door then revolves for a separate preset time at a reduced speed of approx. 2 r.p.m. (adjustable), then returns to normal operating speed. 

4) Safety Sensors on lower door wings: 
A safety sensor is mounted on the trailing door leaf approx. 12 cm above the floor.  If one of these sensors responds owing to a moving person, the system is immediately switched to "stop function".   When clear, the door rotation will revert back to normal speed, (this is to protect area near core). 

5) Safety Sensors on upper door wings: 
The safety sensor strips are mounted on the top frame section of all 4 door wings.  The sensors are placed sloping downwards approx. 5' and scan a safety zone in front of the revolving door wing.  If a person is "caught" in this safety zone, e.g. when walking slowly, the revolving door changes back from walking speed to the idling speed or a "Stop function" is initiated.  Determined when ordering! 

6) Anti-Panic device: 
The 4 door wings are mounted on pivot bearings and are held in the form of a cross by spring force.  They can be folded back at any time towards or away from the direction of walking, e.g. in a panic situation (see open position previous page) door wings folded back to the centre column locking themselves in this position. 

The system comes to a halt when the door wings are pushed forward approx. 10 degrees or pressed back 5 degrees. 

7) Electrodynamic Brake: 
To increase the breaking power in an emergency situation such as safety sensors tripped or doors folded, the armature current induced in the driving motor is diverted to the breaking resistor.
