High level audible warning system E2S has considerable experience in this eld and is able to oer full pre and post installation support including assistance with siren selection. With a choice of 45 standard warning tones including many of the standard international signals the A141 can oer up to 4 dierent stages of alarm. A “Hootronic” version of the A141 is also available which replicates the traditional signaling sounds of bells, buzzers, sirens and claxons. By re-playing digital recordings of these products, the Hootronic produces the exact sound but without the reliability and rating problems of electro-mechanical devices. The A141 is the latest in a new generation of high output electronic sounders from E2S which are ideal for wide area and disaster warning applications such as COMAH (Seveso II) Alarm, Toxic Gas Release, Fire, Security, Flood Warning, Tsunami Alert and Civil Defence requiring sound coverage up to 750m.
