Intrinsically
safe
detectors
are used in
hazardous
locations
where
explosive
levels of
gas or
vapors are
normally or
potentially
present. The
SS-I-S
circuit
power levels
are limited
so the
potential to
ignite an
explosive
atmosphere
is
eliminated.
Intrinsically
safe
detectors
need to be
compatible
with system
control
panels for
ground fault
detection
and proper
use.
Consult the
appropriate
listing
agency for
further
information
about the
use of
intrinsically
safe
products. A
barrier must
also be used
in all
intrinsically
safe
applications
and can be
purchased
separately.
Where
applicable,
BASEEFA or
FM must
approve the
barrier used
with the
system.
Intrinsically
safe
detectors
are designed
to provide
protection
and be used
with
compatible
UL listed
control
panels.
SS-I-IS
ionization
smoke
detectors
use
state-of-the
art sensing
chambers.
These
detectors
are designed
to afford
open area
protection
and are for
use with
compatible
two-wire
control
panels only.
Each
detector is
equipped
with two
LEDs that
provide a
local, 360°
visual
indication
of detector
status.
Remote LED
annunciator
capability
is also
included.
Once the
detector
senses a
fire, it
latches in
alarm and
remains in
this
condition
until it is
reset by a
momentary
power
interruption.
The detector
can be
tested by
activating
an internal
reed switch
with a test
magnet.
