Abstract: A wall-mounted enclosure for mounting electrical and electronic equipment and the like, in modular form. The enclosure body takes the form of a mounting assembly, including mounting modules, with each module including a backbone element and a cover element. The backbone element has a horizontally extending backplane bordered by two upstanding side portions, with an interassembly connecting mechanism for joining one backbone element to an adjacent backbone element. The backplane includes a flat mounting surface, with a pattern of preformed pilot holes, and two recessed wiring channels. Interconnection is provided by interlocks and screw anchor points. The cover element includes a horizontally extending cover plate with coverwalls and a cover assembly connecting mechanism for joining one cover element to another cover element. Adjacent cover elements are joined by mutual engagement of a mating tab and slot, and by screw anchor points.

Abstract: A network control unit for monitoring and controlling all of the operational components of a facility management system, the unit including a modular base frame having a wiring board assembly mounted on the back, a number of termination board assemblies mounted on the front of the frame and being operably connected to the wiring board assembly, one or more function modules, digital control modules, expansion modules, and a network control module are mounted on the front of the frame and operably connected to the wiring board assembly.
