Door Technology - Hold Open Devices & Mechanisms

Fires develop quickly and frequently unnoticed. This means that doors need to be closed securely between the fire lobbies, in order to prevent the dispersion of deadly smoke gases. 

The use of buildings partly requires that doors are left open for a short period of time (e.g. for the transportation of goods). A hold-open device is required in order to keep the door open.

GEZE has a complete range of hold-open devices specially designed for the use in preventative fire protection.

Additionally we have a multitude of hold-open mechanisms for both overhead and integrated door closers, as well as for automatic swing door drives. These can be integrated individually and according to your requirements in the building concept and create a hold-open device when used together with a smoke switch control unit (RSZ6).
