Electro-magnets for hold-open systems The statutory regulations which apply in many countries allow fire and smoke doors to be held open for a limited period of time by electro-magnetic hold-open devices which, in the event of a fire, are de-energised to release the door so as to enable automatic closing. Such systems consist of a hold-open device, fire/smoke detection and alarm system, power supply and release device, and generally have to be approved by an accredited institute or building authority (in Germany: the German Institute for Building Technology, Berlin). Electro-magnets are devices which hold open fire and smoke doors. In the event of a fire, the hold-open magnet is deenergised by the release device responding to a signal from the fire detector. The automatic closing action is provided by door closers which, in Germany, must correspond to DIN EN and be third-party verified. It must also be possible to manually release the holdopen device. According to the guidelines for hold-open systems applicable to Germany, a manual release pushbutton is necessary when employing electromagnets in such applications. The pushbutton employed must be red, carry the wording Close door, be located in the immediate vicinity of the door, and must not be hidden when the door is in its hold-open position. 0 V AC ± % 0 V AC ± % MAG Z Z-K MAG MAG HT HT = Electro-magnet HT = Manual release pushbutton MAG = = Smoke detector (ceiling-mounted) Z = Smoke detector (lintel-mounted) Z-K = Smoke detector (lintel-mounted) F Approval certification Electro-magnets of the series DOA 00 for v AC/DC are tested and third-party verified by the Verband der Sachversicherer (VdS) e.v., Cologne (Association of Property Insurers), and have been approved by the German Institute for Building Technology (DIBt), Berlin, for use in combination with the DOA Z smoke detector, the DOA smoke detector and other reputable smoke detector systems, (e.g. with DOA Z /: approval certificate No. Z-6.-). In Germany, inspection and approval of the holdopen system is additionally required., GB
