Wide Area Signaling

High Power Electronic and Motor Driven Sirens

Typically, wide area signalling alarm systems such as horn loudspeakers or PA loudspeakers consist of three individual sounders that are pole-mounted at 120° to give full 350 coverage; in order to minimise cabling costs, the systems are often battery powered and
are radio controlled.

As well as providing wide area coverage, such systems are often used on building and construction sites, where they provide excellent protection levels for the workforce. Typically, the horn loudspeakers are initiated from radio manual call points, either through a system of master/slave control panels or directly if the system is self contained.

Mobility is a key feature, with the individual units being moved around the site as the work progresses. Wide area warning sirens and alarm systems are particularly useful on a temporary basis when construction work is being carried out on large or congested sites or for more permanent installations like those needing to meet obligations under the Control of Major Accident Hazard (COMAH) regulations.
