BExH120 'Belltronic' Explosion Proof Bell
The flameproof BExH120 Belltronic Signalling Bell is suitable for Zone 1, 2, 21 & 22 applications. Approved to IECEx, ATEX, Ex EAC and INMETRO standards. The BExH120 authentically reproduces the traditional sound of a electro-mechanical bell whilst providing a significantly higher level of performance and reliability.
The digitally stored bell recording is output via a class D amplifier achieving sound levels exceeding the performance of a mechanical bell whilst offering a continuously rated signal. The radial horn design not only physically emulates the traditional bell it also replicates the distribution of the audible signal.
