SYSTEM OVERVIEW
Before the operation of the unit is described, it is essential to understand three
fundamental features.
Audio Verification.
Audio verification is achieved by connecting microphones, fitted throughout a protected premises, to
the AV Unit.
The AV Unit is connected to an existing alarm system which provides it with information on the alarm
status ( set, alarm, communication successful)
When an alarm is triggered the alarm signal is sent to a central monitoring station via
the Digital Communicator, Red care or Modem (existing equipment as part of the alarm system)
Once the monitoring station has received and acknowledged the alarm signal they will
then dial back in to the site using a standard telephone and the AV Unit will then provide
a "Listen in" facility.
The AV unit will NOT provide Alarm Detection or Alarm Signalling
The Central station will have a series of facilities to help them identify if the alarm is false or if the site
requires policing.
Each central station will have there own particular procedures for dealing with audio verification and
you should consult your central station for details.
The AV unit has the ability to comply with every existing procedure, you will have to program the unit
in specific ways to comply with the requirements of some central stations (see application notes)
