• The detector must be mounted on a rigid surface in a
low vibration area .
• Dense fog, rain or ice can absorb IR radiation and
reduce the sensitivity of the detector . To ensure
optimum performance, be certain that the internal
optical heater is enabled on detectors that are used in
applications where snow, ice, and condensation are
likely to occur .
• Although IR detectors are less affected by smoke than
other detectors, the X33AF PL should not be placed
where rising combustion products can obscure its
vision . If smoke is expected before fire, smoke or other
alternative detectors should be used in conjunction
with the X33AF PL . For indoor applications, if dense
smoke is expected to accumulate at the onset of a
fire, mount the detector on a side wall at least a few
feet (approximately 1 meter) down from the ceiling .
• If possible, fire tests should be conducted to verify
correct detector positioning and coverage .
• For ATEX/IECEx installations, the X33AF PL detector
housing must be electrically connected to earth
ground .
DETECTOR ORIENTATION
Refer to Figure 2 and ensure that the oi plate will be
oriented as shown when the X33AF PL is mounted and
sighted . This will ensure proper operation of the
oi system
and will also minimize the accumulation of moisture and
contaminants between the
oi plate and the viewing
windows .
IMPORTANT
If removed, the oi plate
must
be securely
tightened to ensure proper operation of the oi
system (40 oz./inches [28.2 N/cm] recommended).

PROTECTION AGAINST MOISTURE DAMAGE
It is important to take proper precautions during installation
to ensure that moisture will not come in contact with the
electrical connections or components of the system . The
integrity of the system regarding moisture protection must
be maintained for proper operation and is the responsibility
of the installer .
If conduit is used, we recommend installing drains,
according to local codes, at water collection points to
automatically drain accumulated moisture .
It is also recommended to install at least one breather,
according to local codes, at upper locations to provide
ventilation and allow water vapor to escape .
Conduit raceways should be inclined so that water will
flow to low points for drainage and will not collect inside
enclosures or on conduit seals . If this is not possible, install
conduit drains above the seals to prevent the collection
of water or install a drain loop below the detector with a
conduit drain at the lowest point of the loop .
Conduit seals are not required for compliance with
explosion-proof installation requirements, but are highly
recommended to prevent water ingress in outdoor
applications . Units with M25 threads must use an IP66
washer to prevent water ingress .
WIRING PROCEDURE
Wire Size and Type
The X33AF PL can only be used with the AutroSafe
IFG system, and must be connected to the BSD-340
PowerLoop driver .
The system should be wired according to local codes .
The wire size selected should be based on the number
of detectors connected, the supply voltage and the cable
length . Typically 16 AWG or 2 .5 mm
2 shielded cable is
recommended . Wires should be stripped 3/8 inch (9 mm) .
A minimum input voltage of 18 Vdc must be present at
the X33AF PL .
NOTE
Re fe r to “ Powe r C o n s u m p t i o n” i n t h e
“Specifications” section of this manual.
The use of shielded cable is required to protect against
interference caused by EMI and RFI . When using cables
with shields, terminate the shields as shown in Figures 7
through 12, and Figure 15 . Consult the factory if not using
shielded cable .
In applications where the wiring cable is installed in
conduit, the conduit must not be used for wiring to other
electrical equipment .
