Intruder Alarm

Why install an intruder alarm system?

It is widely accepted that intruder alarms are an effective deterrent against burglars, thereby helping to reduce the likelihood of your home being targetted. However, it is important to understand that an intruder alarm
is not a replacement for good physical security. It should, rather, be regarded as a back-up to good physical and other security measures and precautions employed to protect your home.

Examples of alarms we providing:

Control Panel / Box
This is the heart or nerve-centre of the system and, in a domestic residence, is often situated in a cupboard or
under the stairs. The control panel is connected to the electricity mains but also has a battery back-up facility.

The keypad allows you to input numbers/codes thereby activating or de-activating the alarm. Often placed in
the hallway, not far from the entry/exit point. Mainly used to switch the alarm on and off.

Magnetic Contact Sensors
These are sensors that are generally used to detect the opening of a door or window. There are two parts to
them: a magnet and a contact and are usually fitted to the surface of the window or door. Flush fitting types
are also available.

Movement Sensors/Detectors
Many types are available, PIRs (Passive Infra-Reds) being the most common. They are normally installed in
the corner of a room near the ceiling and detect a rapid change in infra-red energy e.g. by the movement of a
person. Other types include microwave, ultrasonic and combinations of each (dual technology).

Vibration and Acoustic Sensors/Detectors
Vibration sensors detect physical vibrations e.g. where a door or window is banged in a hard manner. Acoustic
sensors detect airborne vibrations e.g. where glass is broken.

Personal Attack Button
Also called a ‘PANIC’ button and has one or two recessed red buttons that, when pressed, causes the alarm to activate immediately and may also transmit a further signal to a remote monitoring station if connected.

Internal Sounder / Bell
This is fitted inside the home and provides a very loud audible warning noise.

External Siren / Bell Box
This is the ’box’ that you will see on the outside of homes and other buildings. It is normally sited quite high up, generally just under the eaves, and should be tamper-proof.

Strobe Flasher
Fitted to the external siren/bell box to give a visual warning of the alarm activation. Can be programmed to
continue flashing after the audio sounder/bell has stopped.

Remote Signalling
With this facility, your alarm activation is transmitted to a remote monitoring station.

The alarm installation company will, for the purposes of identification and convenience, divide your home into
zones when installing your alarm system. These zones are managed by the control unit and can be utilised to
de-activate certain areas of your home at particular times, to alert you to open zones when setting your
alarm and also to provide information when an alarm activation occurs etc.
