HARDWARE
The
GASMAX
CX
is
enclosed
in
a
CSA
/
FM
/
IECEx
certified
anodized
aluminum
explosion
proof
yellow
enclosure
designed
to
protect
the
electronics
and
make
it
easy
for
workers
to
identify
in
industrial
environments.
The
screw
‐
on
front
cover
is
easily
removed
for
installation
and
maintenance;
however,
built
‐
in
user
interface
magnetic
switches
allow
operators
and
technicians
to
adjust,
calibrate
or
troubleshoot
the
GASMAX
CX
without
declassifying
the
area.
Local
sensors
are
contained
in
a
stainless
steel
sensor
head,
typically
attached
to
the
bottom
of
the
GASMAX
CX
as
shown
below.
The
normal
sensor
head
includes
an
integrated
stainless
steel
flame
arrestor
that
must
be
removed
for
the
detection
of
certain
reactive
gases
such
as
chlorine
or
chlorine
dioxide.
If
removed,
the
GASMAX
CX
is
not
certified
for
use
in
hazardous
areas.
See
Chapter
