Musical wireless alerting system

摘要

The musical wireless alerting system includes several detectors (12) which transmit rf signals to a common receiver (14). The detectors (12) include manual switches thereon to allow manual selection of a song or melody. The selection is coded in the form of an audio code which is transmitted to the receiver (14). The receiver (14) detects any rf transmissions and verifies that the received transmissions are identifiable with the receiver (14). Upon verification, the receiver reads the audio code and compares same to a plurality of stored songs or tones within memory for transmission to a speaker which plays the tone or song. Each of the detectors (14) may sense different predefined conditions and indicate different audible indications to be played. The detectors may sense conditions such as opening of the door or depression of a door bell.
