A131 wide area high output electronic sounder

Wednesday, July 1st, 2009

The latest addition to the E2S AlertAlarm Series of high performance electronic sounders is the A131. With a sound output of up to 131dB, the units are designed for use in industrial, construction and small COMAH sites, factory complexes, refineries, civil engineering sites, quarries and airfields; they can also be used to give flood warnings, civil defence warnings and in any situation where a warning has to be broadcast across a wide area. The new A131 has an effective range of over 250 metres and can be fitted with a number of control options including radio control, which enables a complete system with multiple activation points and siren locations to be created quickly and cost effectively as cabling will not have to be laid around the site.
The three-stage A131 offers 45 tones, so it can give different tones for fire, evacuation or security alert. The tone menu includes extremely realistic siren, hooter and bell simulations, indistinguishable from those produced by a traditional electro-mechanical device but at much lower energy requirements. Reliability and operating life are also significantly increased.
Based on proven high efficiency horn designs, the A131 utilises a 100W pressure driver to generate its high output and can be used as a single unit or in clusters of four to provide omni-directional sound output. The unit can be powered from 24VDC, 115VAC or 230VAC, with low current draw at all operating voltages. Battery backup is offered as an option, ensuring that an emergency alarm can be provided even in the event of a power failure, a critical requirement for incidents such as toxic gas release.
