BExSB1
The BExSB1 ideally suits applications requiring a traditinal bell sound designed to warn, call and signal
in areas with explosive atmospheres. The protection type II 2G EEx de IIC T6 allows the signalling bell to
be used without restriction in all Ex areas classified Zone 1 or 2. The signalling bell produces a sound
volume of approx. 105dB(A) at 1 metre. The emphasis of the ring is at approx. 1000Hz, as a result of which
the signal stands out clearly against lower frequency ambient noises. We offer the’Hootronic’ range which
offers the same sound from an all-electronic solution.
