Abstract
Disclosed is a system that can monitor occupied or unoccupied buildings, and annuciate to a distant point, e.g. a digital pocket paper, emergency events such as burglaries, fires, high or low temperature, high or low flow rate in such devices as boilers and many more. The system has a circuit that makes interfacing with most commercial field detectors especially easy, and a circuit that enables the system to easily access telephone lines, so as to transmit annunciation messages.
