Leaving the barrier-free WC If you press the pushbutton mounted on the inside, the following will happen:► The door opens automatically once the set hold-open timehas expired.3.9 Use in a hold-open system If the drive is used on a smoke control door or fire door, the drive will usually be operated in a hold-open system in combination with smoke detectors. The drive of the door will keep the door open either permanently (PERMANENT OPEN) or temporarily (AUTOMATIC). However, in case of a fire, the door must close in order to prevent smoke and fire from spreading. For this reason, the opening automatic of the drive will be automatically shut off as soon as a connected smoke detector detects smoke; this is indicated on the smoke detector by a red LED. The door can then only be opened manually. The hold-open function will be cance- led even if the power supply is interrupted.► A forced flushing may take place at the same time.
