INSTALLATION
NOTE
The recommended lubricant for threads and
O-rings is a silicone free grease (part number
116-005003-001) available from Autronica. Under
no circumstances should a lubricant containing
silicone be used.
DETECTOR POSITIONING
Detectors should be positioned to provide the best
unobstructed view of the area to be protected . The
following factors should also be taken into consideration:
•
Identify all high risk fire ignition sources .
•
Be sure that enough detectors are used to adequately
cover the hazardous area .
•
Be sure that the unit is easily accessible for cleaning
and other periodic servicing .
•
Verify that all detectors in the system are properly
located and positioned so that any fire hazards are
within both the Field of View (FOV) and detection
range of the detector . Autronica's Q1201C Laser
Aimer is recommended for establishing the detector's
FOV . Refer to Appendix A for specific information
regarding detector range and FOV .
•
The detector should be aimed downward at least 10
to 20 degrees to allow lens openings to drain . See
Figure 1 .
The detector should be positioned so
that its FOV does not cover areas outside the
hazardous area.
This will minimize the possibility
of false alarms caused by activities outside the area
requiring protection .
•
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 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 . 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 installations, the X33AF 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 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).
