Regulations for fixing the hold-open device
Electromagnet with corresponding counter plate
Normally, in a hold-open device with an electromagnet and a counter plate, the counter plate is installed on the door itself. The corresponding electromagnet is installed in the matching position on the wall, ceiling or floor – if necessary with an appropriate bracket (see DICTATOR electromagnets).
General note
It must always be ensured that the protection function of the door is not impaired when fixing the counter plate. Under no circumstances can it be drilled through. Furthermore, manufacturer’s specifications in the respective approval of the door must always be observed with regards to installation options.
Please, observe the approval of the door manufacturer!
Installation position
When installing the counter plate on hinged doors, it is recommended that the counter plate fixing screws are not more than 150 mm from the closing edge and from the top or bottom edge of the door leaf. However, the approval of the door manufacturer must always be observed in this respect.
Fixing
On steel doors without reinforcements (e.g. internal stiffening components), blind rivet nuts should be used, as otherwise a permanent attachment of the counter plate cannot be guaranteed.
