1. A security system for monitoring security at a premises comprising:
- a premises controller located at the premises;
a plurality of audio sensors located at the premises and spaced apart from the premises controller, each audio sensor receives audio signals and converts the audio signals to digitized audio signals, each audio sensor including a microphone, a memory storing false alarm digital signatures, and a processor being operative to compare a digitized audio signal received by the audio sensor with the stored false alarm digital signatures stored within said memory to determine whether an alarm condition exists and in the event of the alarm condition being operative to make the digitized audio signal available to the premises controller; and
a central monitoring station located remote from the premises that receives the digitized audio signals from the premises controller and converts the digitized audio signals into audible audio for an operator that is monitoring the premises, wherein at least one of the stored false alarm digital signatures is provided from the central monitoring station.

9. A security system for monitoring security at a premises comprising:
-
a plurality of audio sensors located at the premises that receive audio signals generated at the premises and convert the audio signals to digitized audio signals; a data bus interconnecting each of the audio sensors and receiving the digitized audio signals thereon, wherein each audio sensor includes an identifying data address on the data bus; a premises controller located at the premises and interconnected to said data bus for receiving said digitized audio signals from each of the audio sensors, the premises controller being operative to determine when multiple audio sensors provide digitized audio signals at once whether the digitized audio signals correspond to a false alarm; and a central monitoring station located remote from the premises and interconnected to said premises controller for receiving from the premises controller the digitized audio signals which correspond to alarm conditions for further processing. - View Dependent Claims (10, 11, 12, 13, 17, 18, 19)

14. A method for monitoring security at a premises, which comprises:
-
providing a plurality of audio sensors and a premises controller at the premises, the plurality of audio sensors communicating with the premises controller over a digital network; converting an audio signal at the premises into a first digitized audio signal at a first audio sensor located at the premises; converting the audio signal at the premises into a second digitized audio signal at a second audio sensor located at the premises; receiving the first digitized audio signal at the premises controller; receiving the second digitized audio signal at the premises controller; determining with the premises controller if the first digitized audio signal and the second digitized audio signal correspond to a premises wide false alarm; when the first digitized audio signal and the second digitized audio signal are determined to not correspond with the premises wide false alarm transmitting the first digitized audio signal and the second digitized audio signal to a central monitoring station; and converting the first digitized audio signal and the second digitized audio signal into audio for an operator that is monitoring the premises. - View Dependent Claims (15, 16)
