Security Overview

The system comprises various components linked via a hardwired network or a fully wireless configuration. The system makes use of the basic components such as the control panel - the brain of the system, with operating keypad/s through which the commands to the control panel are generated. In order to make the system as secure as possible various peripheral devices will be added. These come in the form of magnetic contacts for doors and in some cases windows.

Next, and probably most popular, are the volumetric space covering devices known as passive infra-red detectors which are generally triggered by a rapid change in ambient temperature. These will cover large areas within a home, office, shop or factory; however they can be unstable in very drafty environments and are not intended for outdoor applications unless specifically designed for that purpose. A number of highly sophisticated passives designed for outdoors and unstable environments are available. To cover large or small expanses of vulnerable glazed areas a glass-break detector can be installed to detect the sound or frequency of breaking glass. In order to create an early warning system, outdoor beams can be installed at strategic points in and around the property. These will activate when crossed, indicating that the premises are being approached.

Fixed panic buttons can be installed in strategic, convenient places throughout the premises for use in cases of personal attack or where prompt notification of the monitoring centre is required. Internal and/or external sirens sound give an audible alarm, while an optional strobe light mounted externally, gives reaction staff visual verification of the alarm source.

All these devices are then linked via wireless transmitters or cable, back to the control panel on individual zones or areas.


Why is wireless becoming the preferred option?

We have seen wireless technology become a preferred option especially for customers currently moving into new homes and developments those of which do not want their new home aesthetics damaged by wiring runs and cables glued to interior and exterior walling, another reason why wireless alarm systems have become the replacement to wired alarm systems is that in most cases, when new premises are built, infrastructure in the way of conduit sleeves for cabling of a wired alarm system are usually not installed during the construction phase solely due to the extra cost implications.

With many new single and double story houses being built on poured concrete slab structures and having no open roof access, it becomes almost impossible to drill and fit wiring to an entire house without the wires being run visibly on skirting or outside of the buildings walls to overcome poured concrete slabs.
