Suits all door mounted, push side (fig. 66) 996 Series Electro HO Closers
Typically used on fire rated doors where the hold-open or swing-free feature is required either in high traffic areas for convenience or in situations where it would be difficult to satisfy the maximum opening force requirements of Part M of The Building Regulations.
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 ‘swingfree’ 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.
