Abstract:
1. An alarm system for protecting an environment from an unwanted event, the alarm system including: a detection sensor for detecting sound in the environment, wherein the detection sensor comprises an opening detector for detecting the unwanted event and an electrical or sound signal is transmitted from the opening detector to a microphone for emitting an audio signal, if the unwanted event is detected, to a filter which is connected to an integrator to produce a unique audio signal, wherein the unique audio signal is transmitted to a sensor module adapted to verify the unique audio signal from the detection sensor; and an alarm generation module adapted to generate an alarm if the unique audio signal is verified, wherein verifying the unique audio signal includes utilizing a false trigger guide time interval preceding or following the unique audio signal such that the unique audio signal is indicated as a false trigger if any audio triggering signal is detected within the false trigger guide time interval, wherein the sensor module identifies a location associated with the unwanted event using the unique audio signal.
