Abstract: A communication module for facilitating monitoring an existing alarm system via a cellular telephone network. A microphone receives a specific sound from the existing alarm system, and in response thereto, generates electrical signals. A programmable alarm sound recognition circuitry is in electrical communication with the microphone and recognizes the electrical signals generated by the microphone, and in response thereto, sends a wireless signal to the cellular telephone network alerting a user of the telephone that the existing alarm system has activated. Programmable phone number circuitry is in electrical communication with the programmable alarm sound recognition circuitry and dials the telephone when the programmable alarm sound recognition circuitry is activated.
