DD243 - Audio Confirmation Systems Requirements

Audio confirmation systems requirements

For audio confirmation systems the audio equipment may be triggered by an:

  • Intruder Detector
  • Audio listing device (ALD)

If one of these methods are employed certain rules apply:

  • Audio coverage must match the detection coverage
  • Audio confirmation cannot commence until an alarm has been signalled to the ARC

When an alarm is received at the ARC the listening periods, as a minimum, are:

  • 60 (s) for intruder detection
  • 30 (s) for audio detection

For audio confirmation of intruder detection:

  • at least 10(s) stored audio before an activation
  • at least 15 (s) stored audio after an activation

For audio confirmation of audio detection:

  • at least 1 (s) stored audio before activation
  • at least 15 (s) stored audio after activation
