Monitored Alarms: Does Your Property Need One?

If you’re looking for a reliable intruder alarm, you can’t go too far wrong with a monitored alarm. They’re the only type of alarm that guarantees a response if there are intruders in your home.

Monitored alarms connect to a monitoring station, known as an Alarm Receiving Centre (ARC). If the alarm goes off then it alerts the monitoring station. Personnel at the station will then notify you and contact other key-holders and/or the police, as and when necessary.

Monitored alarms have lots of advantages but they don’t suit everyone. To help you work out if you should install one in your property, we’ve made a list of their benefits and drawbacks.


Guaranteed response

One of the main reasons why property owners install monitored alarms is because they guarantee a response. The monitoring stations that the alarms communicate with operate 24/7, which means no matter when your alarm gets sent off, the station will respond.

Don’t need to be available or rely on others

Another benefit to monitored alarms is that they don’t rely on you or other people you trust being close by. Audible-only and speech dialler alarms depend on someone being available to receive the alert and inspect the property or call the police. Monitored alarms, on the other hand, can do this for you.



A downside to monitored alarms is that they can end up being quite expensive. After you’ve bought and installed one, you’ll need to pay an annual subscription to the monitoring station. Most alarms will also require you to set up an annual maintenance contract with the alarm installation company.

Possible to disable them

Another drawback to monitored alarms is that it’s possible to disable them. If your alarm only communicates with the monitoring station via a phone line and this is cut, this will stop your alarm from alerting anyone. So intruders who know what they’re doing may be able to avoid detection.
