INSTRUCTION MANUAL (ATEX)
BExCS110-05D
Flameproof Combined Sounder / Beacon
1) Introduction
The BExCS110-05D is a second generation flameproof
combined sounder / beacon which is certified to the
European Standards EN 50014: 1997 and EN 50018: 2000
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 5
). The sounder produces output levels in the
110dB(A) 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.
