BExCL15-05D
Flameproof Combined Loudspeaker / Beacon
1) Introduction
The BExCL150-05D is a flameproof combined loudspeaker /
beacon which is certified to meet the requirements of the
ATEX directive 94/9/EC and the IECEx Scheme. The
loudspeaker section produces a 15 watt audio signal and the
beacon section produces a synchronised visual warning
signal. There are three loudspeaker section versions, 8 ohm,
16 ohm or 100V Line transformer. On 100V line transformer
units there are four output tappings and the unit produces
output levels in the 112dB(A) range. The unit can be used in
hazardous areas where potentially flammable atmospheres
may be present. 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.
