The present invention automatically detects the sabotage of an audio transducer such as a microphone in a security system device. An audio transducer generates an electrical signal, which is analyzed to determine if the electrical signal exhibits a predetermined sabotage characteristic. If the electrical signal does exhibit a predetermined sabotage characteristic, then an alarm device trouble signal is transmitted to an alarm control panel for further processing. If, however, the electrical signal does not exhibit a predetermined sabotage characteristic, then the electrical signal is analyzed to determine if the electrical signal exhibits a predetermined alarm characteristic. If the electrical signal does exhibit a predetermined alarm characteristic, then an alarm signal is transmitted to the alarm control panel for further processing.
