IMPORTANT
Be sure to read and understand the entire
instruction manual before installing or operating
the ame detection system. Any deviation from
the recommendations in this manual may impair
system performance and compromise safety.
ATTENTION
The X33AF includes the Automatic Optical
Integrity ( oi® ) feature — a calibrated performance
test that is automatically performed once per
minute to verify complete detector operation
capabilities. No testing with an external test lamp
is approved or required.
DESCRIPTION
The X33AF is a multispectrum infrared (IR) ame detector.
It provides unsurpassed detection of res from light to
heavy hydrocarbon fuels combined with the highest
degree of false alarm rejection. The detector has Division
and Zone explosion-proof ratings and is suitable for use in
indoor and outdoor applications.
The X33AF contains three IR sensors with their
associated signal processing circuitry. The standard
output conguration includes re, fault and auxiliary
relays. Output options include:
– 0 to 20 mA output (in addition to the three relays)
– HART communication.
A tricolor LED on the detector faceplate indicates normal
condition and noties personnel of re alarm or fault
conditions.
Microprocessor controlled heated optics increase
resistance to moisture and ice.
The X33AF housing is available in copper-free aluminum
or stainless steel, with NEMA/Type 4X and IP66/IP67
rating.
OUTPUTS
Relays
The standard detector is furnished with re, fault and
auxiliary relays. All three relays are rated 5 amperes at
30 Vdc.
The Fire Alarm relay has redundant terminals and normally
open / normally closed contacts, normally de-energized
operation, and latching or non-latching operation.
The Fault relay has redundant terminals and normally
open contacts, normally energized operation, and latching
or non-latching operation.

Page 2
The Auxiliary relay has normally open / normally closed
contacts, and is congurable for energized or de-energized
operation, and latching or non-latching operation.
0 to 20 mA Output
A 0 to 20 mA output is available as an option (in addition
to the three relays). This option provides a 0 to 20 mA dc
current output for transmitting detector status information
to other devices. The circuit can be wired in either an
isolated or non-isolated conguration and can drive a
maximum loop resistance of 500 ohms from 18 to 19.9
Vdc and 600 ohms from 20 to 30 Vdc. Table 1 indicates
the detector status conditions represented by the various
current levels. The output is calibrated at the factory, with
no need for eld calibration. A model with relays and
0-20 mA with HART is also available. Refer to Addendum
number 116-P-X33AFADDENDUM/YGB for complete
details.
NOTE
The output of the 0 to 20 mA current loop is not
monitored by the fault detection circuitry of the
X33AF. Therefore, an open circuit on the loop will
not cause the fault relay to change state or the
detector status LED to indicate a fault.The status of
the LED always follows the status of the relays.
An alarm condition will normally over-ride a fault condition,
unless the nature of the fault condition impairs the ability
of the detector to generate or maintain an alarm output,
i.e. loss of operating power.
LED
A tricolor LED on the detector faceplate indicates normal,
re alarm and fault conditions. Table 2 indicates the
condition of the LED for each status.
Table 2—Detector Status Indicator
OPICAL INTEGRITY ( oi )
Automatic oi
The X33AF includes the Automatic Optical Integrity
( oi ) feature — a calibrated performance test that is
automatically performed once per minute to verify
complete detector operation capabilities.No testing with an
external test lamp is required. The detector automatically
performs the same test that a maintenance person with a
test lamp would perform — once every minute, 60 times
per hour. However, a successful Automatic oi test does
not produce an alarm condition.
The Protect•IR signals a fault condition when less than
half of the detection range remains. This is indicated by
the Fault output relay and is evident by the yellow color of
the LED on the face of the detector. The oi fault condition
is self-clearing if the optical contamination is temporary. If
the contamination is not automatically cleared and the oi
fault remains, the detector may require cleaning or service.
See the "Troubleshooting" section for further information.
Magnetic oi / Manual oi
The detector also incorporates both Magnetic oi (Mag
oi ) and Manual oi (Man oi ) features that provide the
same calibrated test as the Automatic oi , and in addition
actuates the Alarm output to verify operation for preventive
maintenance requirements. These features can be
performed at any time and eliminate the need for testing
with a non-calibrated external test lamp.

CAUTION
These tests require disabling of all extinguishing
devices to avoid release resulting from a
successful test.
The Mag oi test is performed by placing a magnet by
the marked location (Mag oi ) on the outside of the
detector (see Figure 2). The Man oi test is accomplished
by connecting the oi lead (terminal 22) to power supply
minus via an external switch.The magnet or switch must be
held in place for a minimum of 6 seconds to complete the
test. Either of these test methods activates the calibrated
IR emitters. If the resulting signal meets the test criteria,
indicating that greater than half of the detection range
remains, the Alarm output changes state, the indicating
LED changes to red, and the 0-20 mA current output
goes to 20 mA. This condition remains until the magnet is
removed or the switch is released, regardless of whether
the relays are set for latching or non-latching operation.
If less than half of the detection range remains, no alarm
is produced and a fault is generated. The fault indication
can be reset by momentarily applying the Mag or Man oi
switch.
NOTE
Refer to Appendix A for FM verification of the
Optical Integrity oi function.
COMMUNICATION
The X33AF is furnished with an RS-485 interface for
communicating status and other information with external
devices. The RS-485 supports MODBUS protocol, with
the detector congured as a slave device.
For HART communication, connect a HART communicator
across a 250 ohm resistor in the 0-20 mA loop.
DATA LOGGING
Data logging capability is also provided. Status conditions
such as normal, power down, general and oi faults, pre-
alarm, re alarm, time and temperature are recorded.
Each event is time and date stamped, along with the
temperature and input voltage. Event data is stored in
non-volatile memory when the event becomes active, and
again when the status changes. Data is accessible using
the RS-485 port.
INTEGRAL WIRING COMPARTMENT
All external wiring to the device is connected within the
integral junction box. The screw terminals accept wiring
from 14 to 24 AWG. The detector is furnished with four
conduit entries, with either 3/4 inch NPT or M25 threads.
DETECTOR SENSITIVITY LEVELS
There are four factory congured sensitivity levels
available for the X33AF Flame Detector:
Very High, Medium, Low and T-Low.
The following criteria should be considered when
choosing a sensitivity level for the intended application:
• Detector placement
• Speed of response based on fuel type and re size
(see Appendix A for response times)
• Distance between the hazard and the ame
detector
Recommended sensitivity guidelines are as follows:
Very High: Offshore, Warehousing
Medium: General Duty, Compressors
Low: Offshore, close proximity/high IR
backgrounds
T-Low: Turbine enclosures
Additional information on X33AF Flame Detector
performance results and sensitivities can be found in
Appendix A, the FM Approval and Performance Report.
Consult the factory with any questions on how to choose
the optimum sensitivity level for the intended application.

Instructions, AutroFlame X33AF, 116-P-X33AF/IGB, rev. E, 2013-08-13, P/N 95-8625-17.1, Rev: 2/13

GENERAL APPLICATION
INFORMATION
RESPONSE CHARACTERISTICS
Response is dependent on the detector's sensitivity
setting, distance, type of fuel, temperature of the fuel, and
time required for the re to come to equilibrium. As with
all re tests, results must be interpreted according to an
individual application.
See Appendix A for third-party approved re test results.
Additional re test results are available from Autronica.
IMPORTANT APPLICATION CONSIDERATIONS
In applying any type of sensing device as a re detector,
it is important to know of any conditions that can prevent
the device from responding to re, and also to know
what other sources besides re can cause the device to
respond.
Welding
Arc welding should not be performed within 40 feet
(12.2 m) of the detector congured to very high sensitivity,
within 10 feet (3.0 m) at medium sensitivity, within 5
feet (1.5 m) at T-Low sensitivity, or within 5 feet (1.5 m)
at Low sensitivity. 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 re. Arc welding rods can contain organic binder
materials in the ux that burn during the welding operation
and are detectable by the X33AF. Welding rods with clay
binders do not burn and will not be detected by the X33AF.
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 X33AF.
Articial Lighting
The X33AF should not be located within 3 feet (0.9 m) of
articial lights. Excess heating of the detector could occur
due to heat radiating from the lights.
EMI/RFI Interference
The X33AF 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 X33AF.
Non-Carbon Fires
The X33AF is a multiple spectrum IR device with detection
limited to carbonaceous fuels. It should not be used to
detect res from fuels that do not contain carbon, such as
hydrogen, sulfur, and burning metals.
IMPORTANT SAFETY NOTES
WARNING
Do not open the detector assembly in a hazardous
area when power is applied. The detector contains
limited serviceable components and should never
be opened. Doing so could disturb critical optical
alignment and calibration parameters, possibly
causing serious damage.
CAUTION
The wiring procedures in this manual are intended
to ensure proper functioning of the device under
normal conditions. However, because of the
many variations in wiring codes and regulations,
total compliance to these ordinances cannot be
guaranteed. Be certain that all wiring complies
with the NEC as well as all local ordinances. If
in doubt, consult the authority having jurisdiction
before wiring the system. Installation must be
done by a properly trained person.
CAUTION
To prevent unwanted actuation or alarm,
extinguishing devices must be disabled prior to
performing system tests or maintenance.
CAUTION
The multispectrum IR ame detectors are to be
installed in places where the risk of mechanical
damages is low.
ATTENTION
Remove the protective cap from the front of the
detector before activating the system.
ATTENTION
Observe precautions for handling electrostatic
sensitive devices.

Instructions, AutroFlame X33AF, 116-P-X33AF/IGB, rev. E, 2013-08-13, P/N 95-8625-17.1, Rev: 2/13

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 re 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 re 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 specic 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 re, 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
re, mount the detector on a side wall at least a few
feet (approximately 1 meter) down from the ceiling.
• If possible, re 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).

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
ow 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/
IP67 washer to prevent water ingress.
WIRING PROCEDURE
Wire Size and Type
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 mm2shielded 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.
NOTE
Refer to “Power Consumption” in the
“Specications”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.
If disconnection of power is required, separate disconnect
capability must be provided.
CAUTION
Installation of the detector and wiring should be
performed only by qualied personnel.
Detector Mounting
Install the mounting arm assembly on a rigid surface.
The ideal installation surface should be free of vibration
and suitable to receive 3/8 inch (M9) bolts with a length
of at least 1 inch (25 mm). The surface must also have
sufficient capacity to hold the detector and mounting
arm weights (See "Specications" section). Refer to the
Q9033 Mounting Arm and Collar Attachment Manual (95-
8686) for additional mounting information. See Figure 3
for dimensions.

2. Check all eld wiring to be sure that the proper
connections have been made.
IMPORTANT
Do not test any wiring connected to the detector
with a meg-ohmmeter. Disconnect wiring at
the detector before checking system wiring for
continuity.
3. Make the nal sighting adjustments and use a 14 mm
hex wrench to ensure that the mounting arm assembly
is tight.
EOL Resistors
To ensure that the insulating material of the wiring terminal
block will not be affected by the heat generated by EOL
resistors, observe the following guidelines when installing
the resistors.
1. Required EOL resistor power rating must be 5 watts
minimum.
NOTE
EOL resistors must be ceramic, wirewound
type, rated 5 watts minimum, with actual power
dissipation not to exceed 2.5 watts. This applies
to ATEX/IEC installations only.
2. Resistor leads should be cut to a length of
approximately 1 1/2 inches (40 mm).
3. Bend the leads and install the EOL resistor as shown
in Figure 6.
4. Maintain a 3/8 inch (10 mm) minimum gap between
the resistor body and the terminal block or any other
neighboring parts.
NOTE
The EOL resistor can only be used within the
ameproof terminal compartment. Unused conduit
entries shall be closed with suitable blanking
elements.

STARTUP PROCEDURE
When installation of the equipment is complete, perform
the “Fire Alarm Test” below.
FIRE ALARM TEST
1. Disable any extinguishing equipment that is connected
to the system.
2. Apply input power to the system.
3. Initiate an oi test. (See “Magnetic oi / Manual oi ”
under Optical Integrity in the Description section of
this manual.)
4. Repeat this test for all detectors in the system. If a unit
fails the test, refer to the “Troubleshooting” section.
5. Verify that all detectors in the system are properly
aimed at the area to be protected. (The Autronica
Q1201C Laser Aimer is recommended for this
purpose.)
6. Enable extinguishing equipment when the test is
complete.
TROUBLESHOOTING
WARNING
The sensor module (“front” half of the detector)
contains no user serviceable components
and should never be opened. The terminal
compartment is the only part of the enclosure that
should be opened by the user in the eld.
1. Disable any extinguishing equipment that is connected
to the unit.
2. Inspect the viewing windows for contamination
and clean as necessary. The detector is relatively
insensitive to airborne contaminants, however, thick
deposits of ice, dirt, or oil will reduce sensitivity.
(Refer to the “Maintenance” section for complete
information regarding cleaning of the detector viewing
windows.)
3. Check input power to the unit.
4. If the re system has a logging function, check the re
panel log for output status information. See Table 3
for information regarding 0 to 20 mA output.
5. Turn off the input power to the detector and check all
wiring for continuity. Important: Disconnect wiring
at the detector before checking system wiring for
continuity.
6. If all wiring checks out and cleaning of the oi plate/
window did not correct the fault condition, check for
high levels of background IR radiation by covering the
detector with the factory supplied cover or aluminum
foil. If the fault condition clears within 6 minutes or
less, extreme background IR is present. Re-adjust
the view of the detector away from the IR source or
relocate the detector.
If none of these actions corrects the problem, return the
detector to the factory for repair.
NOTE
It is highly recommended that a complete spare
be kept on hand for eld replacement to ensure
continuous protection.

MAINTENANCE
IMPORTANT
Periodic flamepath inspections are not
recommended, since the product is not intended
to be serviced and provides proper ingress
protection to eliminate potential deterioration of the
amepaths.
WARNING
The sensor module (“front” half of the detector)
contains no user serviceable components
and should never be opened. The terminal
compartment is the only part of the enclosure that
should be opened by the user in the eld.
NOTE
Refer to the X33AF Safety Manual (116-P-X33AF-
SIL2/CGB) for specific requirements and
recommendations applicable to the proper
installation, operation, and maintenance of all SIL-
Certied X33AF ame detectors.
To maintain maximum sensitivity and false alarm
resistance, the viewing windows of the X33AF must be
kept relatively clean. Refer to the procedure below for
cleaning instructions.
CLEANING PROCEDURE
CAUTION
Disable any extinguishing equipment that is
connected to the unit to prevent unwanted
actuation.
To clean the windows and oi plate, use Autronicas window
cleaner (part number 116-001680-001) and a soft cloth,
cotton swab or tissue and refer to the following procedure.
1. Disable any extinguishing equipment that is
connected to the unit.
2. Since the X33AF is less affected by contamination
than other detectors, removal of the oi plate is needed
only under extreme conditions. In addition, it is not
necessary to achieve perfect cleanliness, because
IR is not signicantly absorbed by slight lms of oil
and/or salt. If a fault condition is still indicated after
cleaning, remove and clean the oi Plate Removal and
Replacement procedure.
3. In all environments, clean all three viewing windows
and reector surfaces thoroughly. Use a cotton
swab and Autonicas window cleaning solution. Use
Isopropyl alcohol for contaminations that Autronicas
window cleaning solution can not remove.
IMPORTANT
When used in extreme environments, the reective
surface of the detector oi plate may eventually
deteriorate, resulting in reoccurring oi faults and
the need for oi plate replacement.
oi PLATE REMOVAL AND REPLACEMENT
1. Disable any extinguishing equipment that is connected
to the unit.
2. Loosen the two captive screws, then grasp the oi
plate by the visor and remove it from the detector.
See Figure 17.
3. Install the new (or cleaned) oi plate.
NOTE
When installing the stainless steel plate, ensure
that the gasket is present and correctly seated to
prevent moisture or contaminants from penetrating
behind the plate. To ensure even seating, tighten
both screws equally.
4. Re-calibrate the detector's oi system. Refer to the
Inspector Monitor manual (95-8581) for instructions
regarding oi plate replacement and oi system
recalibration.
CAUTION
Do not replace the oi reector plate without also
recalibrating the oi system.
Recalibration of the oi system requires the use of
the Inspector Connector Cable and Inspector Monitor
Software. These two items are included in the oi
replacement kit, or they can be purchased separately. See
Ordering Information for details.

X33AF Reector Plates
X33AF models are supplied with either a black or a
stainless steel reector plate. These plates are not
interchangeable. Order the replacement that matches the
reector plate on your X33AF ame detector.
PERIODIC CHECKOUT PROCEDURE
In compliance with SIL 2, a checkout of the system using the
Mag oi or Man oi feature should be performed regularly
to ensure that the system is operating properly. Refer to
Table 1 in the X33AF Safety Manual (116-P-X33AF-SIL2/
CGB) for frequency of proof tests. To test the system,
perform the “Fire Alarm Test” as described in the “Startup
Procedure” section of this manual.
CLOCK BATTERY
The real time clock has a backup battery that will operate
the clock with no external power for nominally 10 years.
It is recommended that the battery be replaced every
7 years. Return the device to the factory for battery
replacement if needed.
NOTE
If the backup battery is depleted, there is no effect
on the operation of the ame detector, but the time
stamping of the data log may be affected.
