Function in the event of a mains failure
If a mains failure occurs, the door can be manually pushed to the open position, upon
which its controlled closure from any position is ensured by spring power, whereby
the motor acts as a fixed damper according the principle of a generator.
Function in the event of a fire alarm
Independently of the present door position, the door is closed in a controlled fashion
by means of spring power. After the door has been opened by an escaping person, it
is closed in a controlled way by spring power.
As soon as the fire alarm has been invalidated, the reset button installed on one side
of the drive unit must be actuated, upon which the drive unit continues to operate in
the mode which had been activated prior to the fire alarm.
