Electromagnetic door controls
The Briton 996 Series is a range of closers with an integrated electro-magnetic hold open mechanism. Each unit can be set to either 'hold-open' or 'swing-free' operation. In either case the spring closing function of the closer can be temporarily disabled to allow free passage. When de-activated via a connection to the building fire alarm or smoke detection system, the electromagnet disengages and the door closer closes the door in the normal manner to maintain fire safety.
