Monitoring Alarm and CCTV Installations

There are a number of considerations with regard to monitored alarms and systems requiring a police response. These will vary depending on the type of monitoring required.

Essentially, there are two approaches to monitoring alarms:

  • User/owner monitored - with notifications via speech or voice dialler to keyholders, these could be trusted family or friends.
  • Alarm Receiving Centre (ARC) - notifications going via a manned ARC, with the ARC contacting the keyholders or the appropriate emergency service.

Police Response Installations

Police response systems are subject to more stringent design criteria in order to avoid wasting police time responding to false alarms. Police forces will only respond to what are known as 'confirmed alarm activations' or 'verified alarm signals' - generally two signals of alarm information to be received by the ARC within a pre-set time period. Compliant systems are issued with a Police URN (Unique Reference Number), which is obtained by the installer.

The more demanding design criteria of these installations mean they can only be installed by security companies that have been approved by a UKAS accredited inspectorate body such as the Security Systems & Alarms Inspection Board (SSAIB) or the National Security Inspectorate (NSI). These bodies audit security companies against British and European standards for system design, monitoring, and maintenance; checks also include vetting and training of staff.

DCA Security Systems are NSI accredited and are able to obtain URNs from all police forces.

ARC monitored alarms require two maintenance checks per year.
