An audible or
visual deterrent may be effective in
disrupting the intruder but is unlikely to summon assistance from the
police. Under the current ACPO security systems policy most Police
forces will not respond to an unmonitored alarm system unless there is
first hand evidence that an offence is in progress.
A monitored
alarm system using a digital
communicator, DualCom is
connected 24 hours a day
to an Alarm Receiving Centre manned by professional operators. On
receipt of an alarm signal a key holder is contacted and the
appropriate action taken by the operator to confirm the Alarm is
genuine and the Police or Fire services notified.
