Wide area sounder

With an output at 1m in
excess of 140dB, louder than
a jet engine on full power at
take off, the new A141 high
output disaster siren and
alarm from E2S is the most
powerful device ever
produced by the company.

With a power increase from
100 to 400W, the output of
the A141 is substantially
higher than the A140 it
replaces, giving it an effective
warning range of between
500 and 750m, depending on
the atmospheric conditions.

The unit has a choice of
32 user-selectable warning
tones and with second and
third stage alarm capability,
it is ideal for use in quarries,
on large industrial and
petrochemical sites and for
civil defence requirements.

The A141 generates multiple
internationally recognised
alarm tones including fire,
security, civil defence, alert,
COMAH (SEVESO II) toxic
gas alarms and disaster
warnings for flood, tsunami,
tornado and other severe
weather conditions.

The A141 is powered
from 24VDC or
115/230VAC. The mainspowered
versions can be
fitted with battery backup to
enable it unit to operate for
up to 30 minutes without
mains power; AC power and
battery voltage can be
remotely monitored for
potential faults. Radio
control capability, utilising
secure telemetry for
additional security, is
available to enable wire-free
installation on large sites.

Both AC and DC versions
feature low start-up inrush
current and low operating
current draw.
