A tricolor LED on the detector faceplate indicates
normal, fire alarm, and fault conditions. Table 1
indicates the condition of the LED for each detector
status. The LED is non-latching.
The X3300 is available in aluminum or stainless steel
and features multiple mounting options, including:
• Direct to flexible conduit with the use of a Q9001L
swivel mount
• Direct to conduit elbow mount.
GENERAL APPLICATION
INFORMATION
RESPONSE CHARACTERISTICS
Response is dependent on the type of fuel, the
temperature of the fuel, and the time required for the fire
to come to equilibrium. As with all fire tests, results
must be interpreted according to an individual
application.
See Appendix A for fire test results.
IMPORTANT APPLICATION CONSIDERATIONS
In applying any type of sensing device as a fire
detector, it is important to know of any conditions that
can prevent the device from responding to fire, and also
to know what other sources besides fire can cause the
device to respond.
Welding
Arc welding should not be performed within 40 feet of
the very high sensitivity detector (10 feet for medium
sensitivity detector). It is recommended that the system
be bypassed during welding operations in situations
where the possibility of a false alarm cannot be
tolerated. Gas welding mandates system bypass, since
the gas torch is an actual fire. Arc welding rods can
contain organic binder materials in the flux that burn
during the welding operation and are detectable by the
X3300. Welding rods with clay binders do not burn and
will not be detected by the X3300. However, system
bypass is always recommended, since the material
being welded may be contaminated with organic
substances (paint, oil, etc.) that will burn and possibly
trigger the X3300.
Artificial Lighting
The X3300 should not be located within 3 feet of
artificial lights. Artificial lights should not be positioned
so that they are pointed directly at the detector.
EMI/RFI Interference
The X3300 is resistant to interference by EMI and RFI,
and is EMC Directive compliant. It will not respond to a
5 watt walkie-talkie at distances greater than 1 foot. Do
not operate a walkie-talkie within 1 foot of the X3300.
Non-Carbon Fires
The X3300 is a multiple spectrum IR device with
detection limited to carbonaceous fuels. It should not
be used to detect fires that do not contain carbon, such
as hydrogen, sulfur and burning metals.
INSTALLATION
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.
• Locate and position the detector so that the fire
hazard(s) are within both the field of view and
detection range of the device. Refer to Appendix A
for specific information.
• Be sure that the unit is easily accessible for cleaning
and other periodic servicing.
• For outdoor applications, the detector should be
aimed downward at least 10 to 20 degrees to allow
lens openings to drain. See Figure 1. The detector
