Abstract
An electronic communication system monitor in one embodiment has sensors for sensing electrical and environmental conditions for communication system elements. Control relays connect the elements to a programmable controller. The programmable controller has a keyboard, display, printer and modem for remote communication of information; especially alarms providing notice of operating conditions outside acceptable parameters. A second embodiment provides a logic circuit connected to selected sensors which determines when a combination of conditions exist to cause alarm and automatically activates a remedial device to alleviate a potential problem. The central processor also has: a message synthesizer and a connector for communicating a message using dual-tone multifunction coded signals or digitized voice signals to maintenance, emergency and security personnel or remote computers as appropriate; a memory for accumulating information and report preparation instructions for preparing reports of current alarms, alarm history, current status, relay status, channel monitor, and channel on time reports; and instructions for set-up. Manual or automatic operation is provided.
