ABSTRACT:
A plastic cover covers a surface-mounted junction box which delivers wires to an alarm unit or emergency light or the like which is mounted to the cover. The cover is connected to the junction box by screws which engage threaded holes provided by the junction box. The cover can be mounted to either a single wide junction box or a double wide junction box and provides corresponding holes for connection to either box. The alarm devices can be connected to the cover directly by screws or by a combination of a single screw and a tab which is received into a slot on the cover. The cover and alarm unit together form an architecturally attractive cover for an otherwise industrial appearing junction box. When the cover is attached to the junction box, the box no longer can be seen. The covers can be color coded for a particular alarm service, such as fire, weather warnings, or other emergency conditions.
