IMPORTANT
Be sure to read and understand the entire
instruction manual before installing or operating the
flame detection system.
WARNING
Do not open the detector assembly in a hazardous
area when power is applied. The detector contains
no user serviceable components and should never
be opened. Doing so could disturb critical optical
alignment and calibration parameters, possibly
causing serious damage. This type of damage
could be undetected and could result in failure to
see a fire and/or false alarm.
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 disconnected prior
to performing detection system tests or
maintenance.
ATTENTION
Remove protective cap from front of the detector
before activating the system.
ATTENTION
Observe precautions for handling electrostatic
sensitive devices.
ATTENTION
The X3300 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.

Table 1—Detector Status Indicator

Refer to the “Ordering Information“ section for a
complete list of available options and accessories.
Table 1 indicates the condition of the LED for each
detector status. The LED is non-latching. Fire and Fault
relay condition for each detector status varies
according to the factory configuration.
FACTORY CONFIGURATION OPTIONS
The X3300 is configured at the factory to operate as
specified when ordered. Refer to the descriptions in
Table 2 for a functional explanation of each
configuration option.
NOTE
Factory configurable options cannot be changed in
the field.
4 TO 20 MA OUTPUT
This option provides a 4 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 configuration and can drive a maximum loop
resistance of 500 ohms from 18 to 19.9 volts dc and 600
ohms from 20 to 32 volts dc. Table 3 indicates the
detector status conditions represented by the various
current levels. The output is calibrated at the factory,
with no need for field calibration.
NOTE
The output of the 4 to 20 mA current loop is not
monitored by the fault detection circuitry of the
X3300. Therefore, an open circuit on the loop will
not cause the detector status LED to indicate a
fault.
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 long range detector (10 feet for medium range
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.
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. 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.
• For best performance, the detector should 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.
• Although IR detectors are less affected by smoke than
other detectors, the X3300 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 X3300. 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.
WIRING REQUIREMENTS
WIRE SIZE AND TYPE
The system should be wired using a 14 to 22 gauge (1.3
to 0.5 mm2) cable. The wire size selected should be
based on the number of detectors connected, the
supply voltage and the cable length. A minimum input
voltage of 18 vdc must be present at the X3300.
The use of shielded cable is recommended to protect
against interference caused by EMI and RFI. When
using cables with shields, terminate the shields as
shown in Figures 6 through 8.
In applications where the wiring cable is installed in
conduit, the conduit should not be used for wiring to
other electrical equipment.
CAUTION
Installation of the detector and wiring should be
performed only by qualified personnel.
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 wiring pigtail for the X3300 is factory
sealed for easy installation onto a junction box where
electrical connections are made. 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, drains must be installed at water
collection points to automatically drain accumulated
moisture. Conduit breathers should be installed at
upper locations to provide ventilation and allow water
vapor to escape. At least one breather should be used
with each drain.

B1974

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.
The detector is factory sealed. Conduit seals are not
required for compliance with explosion-proof installation
requirements.

oi PLATE ORIENTATION
Refer to Figure 4 and insure that the oi plate will be
oriented as shown when the X3300 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. The oi plate includes an arrow,
which should be pointed in the up direction, indicating
that the oi plate and detector are correctly oriented.
IMPORTANT
The oi plate must be securely tightened to ensure
proper operation of the oi system.
INSTALLATION USING Q9003 MOUNTING
BRACKET
1. Install the swivel mounting bracket assembly on the
wall or ceiling. The installation surface should be
free of vibration. Refer to Figure 8 for dimensions of
the Q9003 swivel mount.
2. Make field connections following local ordinances
and guidelines in this manual. Refer to Figures 2
and 6. If the detector is equipped with 4 to 20 mA
output, refer to Figure 7.
NOTE
Connect the shield to power supply minus (circuit
ground) at the detector end. At the fire panel end,
connect the shield and power supply minus to
chassis ground through a 0.47 µF 400 Volt non-
polarized capacitor (not supplied).
3. Check all field 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.
4. Make the final sighting adjustments and ensure that
the mounting bracket hardware is tight.

OPTICAL INTEGRITY (oi)
AUTOMATIC oi
The X3300 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. A successful
automatic oi test does not produce an alarm condition.
The Protect•ir signals a fault condition when less than
50% of the detection range remains. This is indicated
by the Fault relay and is evident by the amber color of
the LED on the face of the detector. See the
“Troubleshooting” section for further information.
MANUAL oi
The detector also incorporates a manual oi feature that
provides the same test as the automatic oi, and in
addition actuates the Alarm relay to verify output
operation. The manual oi feature is available in all
models and can be performed at any time. This test
requires bypass of all extinguishing devices to avoid
release resulting from a successful test.
The manual oi test is activated by connecting the white
lead to power supply minus. This places the detector in
a special operating mode. First, the device de-latches
any latching outputs. Next, the IR emitters are activated.
If the resulting signals meet the test criteria, the Alarm
relay changes state and the indicating LED changes to
red. This condition remains until the white lead is
disconnected from dc minus. If the test criteria are not
met, no alarm is produced and no fault is generated.
See the “Troubleshooting” section for further details.
STARTUP PROCEDURE
When installation of the equipment is complete, perform
the “Fire Alarm Test” below.
Allow 20 to 30 minutes for the detector optics to reach
equilibrium. Housing will be warm to the touch.

FIRE ALARM TEST
1. Disable any extinguishing equipment that is
connected to the system.
2. Apply input power to the system.
3. Connect the oi test line to dc minus for 5 to 10
seconds or perform a pan fire test. The alarm relay
will change states and the red alarm LED will
illuminate when the device goes into an alarm
condition.
4. Disengage the oi test line or extinguish the test fire.
If the Alarm relay is configured for the standard
non-latching operation, it will change states and the
red LED will turn off. If the unit has latching relays,
they can be reset by removing input power (0.1
second minimum).
5. Repeat this test for all detectors in the system. If a
unit fails the test, refer to the “Troubleshooting”
section.
6. Verify that all detectors in the system are properly
aimed at the area to be protected.
7. Enable extinguishing equipment when the test is
complete.
TROUBLESHOOTING
WARNING
The detector contains no user serviceable
components and should never be opened.
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 window.)
3. Check input power to the unit.
4 If the fire system has a logging function, check the
fire panel log for relay status and/or 4 to 20 mA
output information. See Table 4.
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
Since the entire unit must be returned to the
factory for repair, it is highly recommended that a
complete spare be kept on hand for field
replacement to ensure continuous protection.
PERIODIC CHECKOUT PROCEDURE
Periodic testing is not required when the detector is
configured for automatic optical integrity testing. If the
X3300 is configured for manual oi operation, a
checkout of the system using the oi feature should be
performed on a regularly scheduled basis to ensure that
the system is operating properly. To test the system,
perform the “Fire Alarm Test” as described in the
“Startup Procedure” section of this manual.
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 flamepaths.
WARNING
The detector contains no user serviceable
components and should never be opened.
To maintain maximum sensitivity, the viewing windows
of the X3300 must be kept relatively clean. Refer to the
procedure below for instructions.
CLEANING PROCEDURE
CAUTION
Disable any extinguishing equipment that is
connected to the unit to prevent unwanted
actuation.
To clean the window and oi plate, use Det-Tronics
window cleaner (part number 001680-001) and a soft
cloth or tissue and refer to the procedure below.
1. Disable any extinguishing equipment that is
connected to the unit.
2. Since the X3300 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 significantly absorbed by slight
films of oil and/or salt. If a fault condition is still
indicated after cleaning, remove and clean the oi
plate using the procedure below.
3. Clean all three viewing windows and reflector
surfaces thoroughly using a clean cloth, cotton
swab or tissue and Det-Tronics window cleaning
solution. If a stronger solution is needed, isopropyl
alcohol may be used.
OiPLATE REMOVAL
1. Remove the oi plate from the detector by loosening
the oi plate knob.
2. Thoroughly clean the oi plate reflective surfaces,
holding it by its edges to avoid leaving fingerprints
on the inside reflective surface.
3. Re-install the oi plate. Ensure that the plate is flat
on the detector surface. Tighten the oi plate knob
securely (40 oz/inches).
NOTE
If the oi plate is removed, be sure to install the
original oi plate. oi plates are not interchangeable
and should not be mixed with oi plates from other
detectors.
NOTE
If corrosive contaminants in the atmosphere cause
the oi plate surface to deteriorate to the extent that
it is no longer possible to restore it to its original
condition, it must be replaced. Consult factory for
oiplate replacement procedure.

REPLACEMENT PARTS
The detector is not designed to be repaired in the field.
If a problem should develop, refer to the
Troubleshooting section. If it is determined that the
problem is caused by an electronic defect, the device
must be returned to the factory for repair.
DEVICE REPAIR AND RETURN
Prior to returning devices, contact the nearest local
Detector Electronics office so that a Service Order
number can be assigned. A written statement
describing the malfunction must accompany the
returned device or component to expedite finding the
cause of the failure.

OPTICAL FAULT:
The detector generated an optical fault in the presence of contamination on any single or combination of lens
surfaces verifying that the detector performs an optical integrity (oi) test for each sensor. Upon removal of the
contaminant the detector fault was cleared and the detector was verified to detect a fire.
