GEZE door hold open magnet

April 14, 2014 by  


Wall mounted electromagnetic door hold open devices are used for holding open fire doors which have mechanical door closers fitted. They must be connected to a smoke detection system or fire alarm panel which, in the case of fire, interrupts the clamping power supply.  Thus the door is released and is closed by the door closer.  Suitable for use with power size 3-6 door closers, suitable for use on timber doors of any width up to 1450mm, 24v lower power unit, integrated test button on the unit, to be used with counter plate C or counter plate E for extreme angles.
