COMBINED AUDIBLE AND VISUAL SIGNALING DEVICE |
摘要 |
Push button controlled wireless transmitters send digitally encoded signals to a plug-in receiver/signaling device. The receiver/signaling device has a microprocessor suitably programmed to respond to signals from a transmitter bearing the discrete address of the receiver, and to decode a transmitter identification code. Thereupon the microprocessor supplies an audio output circuit with signals to simulate selectively mechanical front or back door chimes, and supplies signals to energize a strobe lamp to emit bursts of multiple flashes, the number of flashes in a burst identifying the specific transmitter, whereby a person with a hearing deficiency is informed as to which transmitter is being actuated.
