Introduction
The BExCS110-05D is a flameproof combined sounder /
beacon which is certified to the European Standards EN
60079-0:2006 and EN 60079-1:2007 and meets the
requirements of the ATEX directive 94/9/EC. The sounder
section produces loud audio warning signals and the beacon
section produces a synchronised visual warning signal. The
unit can be used in hazardous areas where potentially
flammable atmospheres may be present. Thirty-two different
first stage audio alarm sounds can be selected by internal
switches, and each one can be externally changed to a
second or third stage alarm sound (see tone table on Page
The sounder produces output levels in the 110dB(A)
5).
range and the beacon produces an output level of 5 joules.
The unit can be used in Zone 1 and Zone 2 areas with gases
in groups IIA and IIB and with Temperature Classifications of
T1, T2, T3 and T4.
