E2S BExH120-D(F/R) Explosion Proof Sounders

E2S BExH120-D(F/R) Explosion Proof Sounders


E2S BExH120-D(F/R) Explosion Proof Sounders for Hazardous Area Signalling Applications

The BExH120 Hootronic Explosion Proof Sounders are suitable for Zone 1, 2, 21 & 22 applications. Approved to IECEx, ATEX, Ex EAC and INMETRO standards. The BExH120 authentically reproduces the traditional sounds of electro-mechanical devices whilst providing a significantly higher level of performance and reliability. The E2S Hootronic series of products faithfully reproduce the sounds made by legacy electro-mechanical signalling devices but in a modern, reliable and cost effective way. With output levels of up to 117.5dB(A) at 1 metre the BExH120 surpasses legacy electro-mechanical devices in performance and effectiveness, it is also continuously rated, requires zero maintenance and the signal quality will not degrade with age.
