Burglar Alarm Systems

Burglar (or intrusion) safety alarms are electronic alarms designed to alert the user to a specific danger. E4U Technologies is a Premiere Solutions provider of Burglar Alarm Systems .
There is no doubt that homes and other buildings are less likely to be broken into if they have a professionally fitted alarm system. Most burglars are on the lookout for easy pickings, so an alarm is a good deterrent.
Don't forget that an alarm is only a part of good security. Physical protection, including locks, lighting and 'good housekeeping' are also very important factors that all contribute to making your property an unattractive prospect for thieves.

How does an alarm work?

No matter how complex a system may be, it can always be broken down into the following basic components:

Detection -movement sensor, door contacts, pressure mat
Control -the 'brains of the system', control panel/keypad
Signalling -internal sounder, external sounder, remote monitoring

Detection

Most alarm systems have at least two types of detection device. The most commonly used are:-

Magnetic contacts -which consist of a magnet fitted to the opening part of a door or window and a switch fitted to the frame. When the two parts are separated (when the door or window is opened) the alarm is activated.
Passive Infra-red Receivers -commonly referred to as PIRs, they are generally fitted into the corner of a room and look for changes in temperature, such as an intruder's body heat.

Control

This is where you switch the system on and off, usually by entering a security code. The control equipment monitors the detection devices, and if necessary activates the signalling device.

Signalling

This is where you switch the system on and off, usually by entering a security code. The control equipment monitors the detection devices, and if necessary activates the signalling device.

Audible alarms - these comprise of a bell or siren fitted to the outside of a building to attract attention and frighten off intruders.
Monitored alarms -include a telephone connection to a 24 hour central monitoring station, whose operators can contact your keyholders or may be able to notify police if your alarm activates. An annual fee is charged for this service.
