The Briton electromagnetic hold open device is suitable for use with overhead door closers and floor springs. To avoid inflicting twisting forces on the door leaf it is recommended that the electromagnetic device is fitted in the same horizontal plane as the closing device (or as close as is practical). Failure to do so can result in the door leaf twisting which can prevent the door from closing properly in an emergency.
When used in conjunction with a suitable door closing device, fire alarm and detection system, the Briton electromagnetic hold open devices permit fire doors to be held open during normal operation. In the event of a fire or smoke detection the units are automatically de-activated and the doors will be closed under the normal action of the door closer.
