monitoring in critical safety applications
where personnel, processes
and facilities are at risk. The sensor

technologies (infrared, catalytic

and
electrochemical).
configurable
Asrelays,
with
communication options,
provide broad flexibility. The
device can be remote-mounted up
to 100 ft from the transmitter, enabling
the transmitter to be located
in a personnel-accessible location
while the sensor is closer to potential
hazards. The device is third-party
certified to IEC61508 Level 2 (SIL2)
for both hardware and software,
with certification to global hazardous
area and performance standards,
according to the manufacturer. -

Gas-detection systems alerts
personnel to dangers
The Patrol Series Flashing Sounders
(photo) provide alarming related to
fixed gas detection. These devices
are designed to alert personnel of
the need to evacuate when a hazardous
gas (such as ammonia, carbon
dioxide, Freon, methane, chlorine
and others) is present. These
gas-monitoring systems are designed
for energy generation, wastewater
treatment, landfill applications,

manufacturing,
refrigeration, gas production, agricultural,
chemical use and storage,
and other industrial applications. The
system offers 80 pre-programmed
alarm tones with four stages for distinctive
signaling of specific events.
Such devices are well-suited for environments
with high ambient noise
levels or when the use of hearing
protection may hamper a sounder's
effectiveness, or in bright environments
where visual signals alone
do not suffice. A single device in
heavy-duty industry (>90 dB) can
cover over 350,000 ft3 (visual) and
800,000 ft3 (audio) with an effective
viewing distance of nearly a quarter
of a mile, says the manufacturer. -
