ABSTRACT:
A theft alarm system for use in combination with a digital signal PBX telephone system, includes a plurality of electronic tethers connected to individual pieces of protected equipment. Removal of the tether is automatically detected by a local security monitor which reports the condition to a central security controller via the PBX system. The security controller then provides dial-up reporting of the theft and/or sets an audible alarm at the equipment site.
