ABSTRACT:
A home burglar alarm system, dependent on a telephone line for operability, can be protected by covering the exterior telephone wiring with an enclosure fastened to the building exterior surface. The enclosure conceals and physically shields the telephone wiring form attack by a would-be intruder. As back-up protection, the wiring enclosure is provided with an audible alarm system that is triggered by breakage or destruction of the enclosure.
