Electro-magnets of the series DORMA EM 500 for 24v 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 Techno logy (DIBt), Berlin,

for use in combination with the DORMA RMZ smoke detector

and other reputable smoke detector systems, (e.g. with DORMA RMZ: approval certificate No. Z-6.5-1890). In Germany, inspection and approval of the holdo-pen system is additionally required.

F

Approval certification The statutory regulations which apply in many coun-tries 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 auto matic 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

de-energised 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 1154 and be third-party verified. It must also be possible to manually release the hold-open device. According to the guidelines for hold-open systems applicable to

Germany, a manual release pushbutton is necessary when employing electro-magnets in such applicati-ons. 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.
