Teledata OPEN HOLD ELECTROMAGNETIC Holding Force 50KmFDM5411E
Product Code: FDM5411E
FDM5411E electromagnetic door holder keeps fire doors in the open position under normal conditions and releases them during an alarm. Since keeping fire doors continuously closed makes passage difficult, in practice they are held open with wedges; this renders compartmentation completely ineffective during a fire. The electromagnet solves this contradiction: the door remains open throughout the day and closes automatically upon alarm.
