There's no need to lift carpets to run cables under floor boards, move furniture or drill holes through walls. This generally reduces the installation cost compared to a hard wired system. Wireless alarms are also portable, so can be removed temporarily for decorating or permanently if you decide to move home. The only wire free alarm system which conforms both to British Standards and the Association of Chief Police Officers ACPO Intruder Alarm Policy is a BS 6799 Class VI alarm. This type is typically more expensive than its hard wired counterpart but is a requirement for police monitoring. A monitored alarm is connected to an alarm receiving centre ARC. The alarm panel will communicate with the ARC in the event of alarm activation. The ARC will then notify either the appropriate key holders for the property or the police, depending on the arrangement and other factors.
