Ventouse électromagnétique

Electromagnetic door holder

An electromagnetic door holder keeps a fire door open in day-to-day use and releases it as soon as the power is cut, for example during an alarm: the leaf then closes by itself. This avoids wedging open a door that must remain free to operate. The arrangements shown here differ in their fixing, to the wall, to the floor or suspended.

The choice of model and its wiring depend on the weight of the leaf, its opening direction and the detection system to which it is connected: this is a study to be entrusted to a professional. Tell us about your situation via the contact page. See also Fire accessories and Locks.
