During research interviews by criminologists over the years most burglars (who expressed a preference) said that they were definitely put off by alarms. I personally believe that a monitored alarm is an excellent deterrent.

Examples of monitored alarms systems:

Digcom – Digital Communicator which is connected to the customer’s phone line where a signal goes through to alarm receiving centre.

Dual com – Dual communicator is connected with the alarm receiving centre, customer’s phone line and GSM (mobile) network.

There are two types of intruder or burglar alarm systems:

Wired and Wireless alarms

Wired alarms comprise a number of electronic sensors that are connected to a control panel by low-voltage wiring and are governed by the BS EN 50131 and BS 4737 series of standards. These are installed into new homes and into existing homes during refurbishment as it is more convenient to run the wiring at these times.

Wireless alarms as the word suggests, use battery powered sensors that are ‘connected’ to a control panel by narrowband RF signals (radio signals). These used to be governed by BS 6799, but are now included in the BS EN 50131 series of standards for alarms. These are quick to install and are used for homes where you don’t want to disturb the decor. The only minor downside is that the sensor batteries have to be changed from time to time.

When the sensor is triggered (by sound or a change of temperature, such as that caused by somebody moving in front of a sensor) the sensor will send a signal to the control panel. The control panel will then activate an internal and or external audible and visual alarm.

If the alarm is the type that can send a signal to a remote alarm receiving centre (ARC) it will do so and the ARC will carry out your instructions to inform a range of people, such as a professional keyholding service, you, or another keyholder. Once the ARC has received a confirmation signal from the alarm system the ARC will inform the police if that is what you have arranged for.
