Monitored and unmonitored alarm systems

Today’s selection of home security products is extensive. It offers something for every budget, ranging from simple and cost-effective dummy alarm bell boxes to sophisticated CCTV (closed-circuit television) systems, not to mention add-on extras like smoke and flood detectors.

Many alarm packages are available as a choice of a monitored or unmonitored system.

A monitored system provides additional peace of mind thanks to being connected to a central 'listening' service, also known as a ‘monitoring station’ or ‘receiving centre’; although there is a monthly fee for this facility, it automatically checks whether your alarm has been accidentally activated. If a break-in is suspected, a key holder or the police are contacted immediately.

In comparison, an unmonitored system relies on somebody hearing the bell or siren before any action can be taken, meaning it will ring until the system is switched off. While owners of domestic intruder monitoring equipment do not have any legal responsibilities, legislation allows council environmental health officials to enter premises and silence any alarm that rings continuously for more than 20 minutes; they also have the power to issue a fine for noise pollution.

But, whichever type of system you choose, you will need to nominate two keyholders who are contactable by telephone, have their own transport and are:

· trained to operate the alarm

· able to attend within 20 minutes of activation.

Consult an expert

Before deciding which option best suits your needs, it’s wise to:

1. Speak to the crime prevention officer at your local police station for their alarm recommendations and home security tips.

2. Get specialist advice and a quote from at least three alarm supply companies, choosing those that are registered with:

· National Security Inspectorate [link that opens in a new window to www.nsi.org.uk] or

· SSAIB [link that opens in a new window to www.ssaib.co.uk], the specialist certification body for security services, electronic security and fire systems.

Your system should meet:

· British Standard BS4737 or BS6799 (wire-free) or

· the new European Standard EN50131-1.


3. Contact your home insurer to see:

a) which alarm companies they recommend

b) if installing a system will qualify you for a premium discount – be aware that conditions may apply, eg the alarm:

· meeting certain technical specifications

· being switched on at all times when there’s no one in.

It’s also important to bear in mind that an alarm that is not fitted properly can create problems: don’t do it yourself unless you have the necessary electrical knowledge and practical skills; instead, hire a professional who can install your alarm and explain how to operate it correctly.

Similarly, regular, professional, maintenance of your
system is likely to be money well-spent, as any defects will be spotted and fixed as soon as possible, reducing the likelihood of false alarms.
