The Fireco DorMag SmartSound (843-4317) is a wireless, battery-powered fire door magnet that legally holds fire doors open and releases them to close when the fire alarm sounds. The unit mounts on the wall with a keeper plate on the door, so there is no hard wiring. It is a compact, discreet option that is particularly suited to uneven floors and carpeted areas.
