Audible Only:
An audible-only alarm, or bells-only alarm, does no more than activate an external siren should the alarm be activated. This is the cheapest and most popular option for the average home security system. Think carefully about this choice; consider how you react when hearing an alarm in your street? If you live in a busy neighbourhood which operates a neighbourhood watch scheme, a bells only alarm system may suffice. If you live in a more remote location, would anyone hear or notice your alarm ringing?
In the case of a bells only alarm activation, Police will only respond if a neighbour or passer-by confirms an actual break-in and telephones 999.
However, any burglar alarm is a visual deterrent and is better than no alarm at all. It is always a good idea to have the system maintained and tested regularly.
Monitored:
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. An annual fee is charged for alarm monitoring, this is typically paid directly to the alarm company.
Security alarms requiring police response must meet certain standards including installation of a graded alarm system installed to British and European Standards and an annual maintenance contract from an approved alarm company. If the police were called to 2 false alarms in a rolling 12 month period the response will be downgraded to a lower level of police response. If there are further false activations the police response will be revoked. To help prevent this eventuality, ARC's are required to receive two alarm events within a certain timeframe to initiate a Police response.
