ABSTRACT:
A portable, self-contained device for monitoring a selected local area for occurrence of any one of a plurality of preselected conditions, which device comprises a connector, connecting the device to local, standard telephone lines, a sound synthesizer containing selected sound, words and/or phrases at memory addressable locations capable of outputting a sound signal of message indicative of a selected combination of sounds, words and/or phrases, a successive dialing system for dialing successively a repeatable series of preselected telephone numbers in response to an occurrence of one of the monitored conditions, responsive answering to any one of the series of telephone numbers reached by the dialing system to cause the sound synthesizer to place a sound voice message on the telephone lines and dialing termination of the successive dialing system whereby the termination is responsive to a call back to the device. Further, the synthesizer is provided with TOUCH TONE signaling which can be amplified and used in dialing. The device includes a monitoring device having an alarm condition responsive to a non-connected sound alarm such as a smoke detector or burglar alarm, which alarm operates adjacent the monitoring device for preselected time duration indicative of an alarm condition. The device utilizes the alarm sound system as a local ambient sound detector which allows the sound to be applied to the telephone lines for monitoring or listening to sound at a local station from a remote station whether or not an alarm condition has occurred, but after selected time delay.
