Fire-Lite FM996-L8 — FM Series electromagnetic door holder, wall mounted with surface wiring, catalogued by Fire-Lite as FM996.
It holds a fire or smoke barrier door open until a smoke detector or other switching device drops power, at which point the magnet releases and the door closes. The assembly is an armature contact plate with adjustable pivot mounting fitted to the door and a heavy-duty electromagnet in a plastic enclosure on the wall behind it. A separate closing device is needed.
