Rixson FM998 — flush wall mount electromagnetic door holder for fire and smoke barrier doors, wired concealed into an outlet box.
FM Series holders keep a fire or smoke door standing open and let it go the instant power is interrupted by a smoke detector, panel or remote switch. The assembly is a wall electromagnet plus an armature contact plate on the door. A separate closing device is required: this releases the door, it does not close it.
