E2S BexCS11005D24DC-RD Instruction Manual

1) Introduction
The BExCS110-05D is a flameproof combined sounder /
beacon which is certified to meet the requirements of the
ATEX directive 94/9/EC and the IECEx scheme. 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
5). The sounder produces output levels in the 110dB(A)
range and the beacon has a flash energy 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.
