E2S BExCS110-L1 Instruction Manual

1) Introduction
The BExCS110-L1D is a flameproof combined sounder / LED
beacon which is certified meet the requirements of the ATEX
directive 94/9/EC and the IECEx Scheme. The combined unit
produces both loud audio warning signals and visual warning
signals that 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. Nine different flash patterns can be selected
including a steady ON state and can also be remotely
switched to a second and third flash pattern (see flash pattern
table on page 5). 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.
