Important

Be sure to read and understand the entire instruction manual before installing or operating the flame detection system. Any deviation from the recommendations in this manual may impair system performance and compromise safety.

ATTENTION

The X3301 includes the Automatic oi ® (Optical Integrity) feature — a calibrated performance test that is automatically performed once per minute to verify complete detector operation capabilities.

Testing with an external test lamp is not approved or required.

DESCRIPTION

The X3301 is a multispectrum infrared (IR) flame detector. It provides unsurpassed detection of fires 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 X3301 contains three IR sensors with their associated signal processing circuitry. The standard output configuration includes fire, fault and auxiliary relays. Output options include:

––0 to 20 mA output (in addition to the three relays)

––Pulse output for compatibility with existing Detector Electronics Corporation (Det-Tronics®) controller based systems (with fire and fault relays)

––Eagle Quantum Premier® (EQP) compatible model (no analog or relay outputs)

––HART communication

INSTRUCTIONS

Multispectrum IR Flame Detector

X3301

A tri-color LED on the detector faceplate indicates normal condition and notifies personnel of fire alarm or fault conditions.

Microprocessor controlled heated optics increase resistance to moisture and ice.

The X3301 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 fire, 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.

Rev: 12/13

95-8527

The Auxiliary relay has normally open / normally closed contacts, and is configurable 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 nonisolated configuration 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 field calibration. A model with relays and 0-20 mA with HART is also available. Refer to Addendum number 95-8577 for complete details.

NOTE

The output of the 0 to 20 mA current loop is not monitored by the fault detection circuitry of the X3301. 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.

Table 1—Detector Status Conditions Indicated by Current Level

Current Level (±0.3 mA)	Detector Status
0 mA	Power Fault
1 mA	General Fault
2 mA	oi Fault
3 mA	Hi Background IR Fault
4 mA	Normal Operation
20 mA	Fire Alarm

LON/SLC Output

The EQP model is designed for use exclusively with the Det-Tronics Eagle Quantum Premier system. The detector communicates with the system controller over a digital communication network or LON/SLC (Local Operating Network / Signaling Line Circuit). The LON/ SLC is a fault tolerant, two wire digital communication network arranged in a loop configuration. Analog and relay outputs are not available on this model.

LED

A tri-color LED on the detector faceplate indicates normal condition and notifies personnel of fire alarm or fault conditions. Table 2 indicates the condition of the LED for each status.

NOTE: See "Detector Sensitivity Levels" for additional information.

oi (Optical Integrity) Automatic oi

The X3301 includes the Automatic 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 X3301 signals a fault condition when less than half of the detection range remains. This is indicated by the Fault output 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.

19.2

95-8527

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 at the location marked "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 oi or Man oi switch.

NOTE

Refer to Appendix A for FM verification of the oi function.

Communication

The X3301 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 configured as a slave device.

For HART communication, connect a HART communicator across a 250 ohm resistor in the 0-20 mA loop.

NOTE

The EQP model uses LON/SLC communication. RS-485 and HART communication are not available on the EQP model.

Data Logging

Data logging capability is also provided. Status conditions such as normal, power down, general and oi faults, fire 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 Inspector Connector accessory, RS-485, or the EQP Controller.

Integral Wiring Compartment

All external wiring to the device is connected within the integral junction box. The detector is furnished with four conduit entries, with either 3/4 inch NPT or M25 threads.

Detector Sensitivity Levels

There are four factory configured sensitivity levels available for the X3301 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 fire size (see Appendix A for response times)

•Distance between the hazard and the flame 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 X3301 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.

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 fire to come to equilibrium. As with all fire tests, results must be interpreted according to an individual application.

See Appendix A for third-party approved fire test results. Additional fire test results are available from Det-Tronics.

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 (12.2 m) of the detector configured 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 fire. Arc welding rods can contain organic binder materials in the flux that burn during the welding operation and are detectable by the X3301. Welding rods with clay binders do not burn and will not be detected by the X3301. 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 cause the X3301 to alarm.

Artificial Lighting

The X3301 should not be located within 3 feet (0.9 m) of artificial lights. Excess heating of the detector could occur due to heat radiating from the lights.

EMI/RFI Interference

The X3301 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 (0.3 m). Do not operate a walkie-talkie within 1 foot (0.3 m) of the X3301.

Non-Carbon Fires

The X3301 is a multiple spectrum IR device with detection limited to carbonaceous fuels. It should not be used to detect fires 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 flame detectors are to be installed in places where the risk of mechanical damage 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.

INSTALLATION

note

The recommended lubricant for threads and O-rings is a silicone free grease (p/n 005003001) available from Det-Tronics. 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. The 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 X3301 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 X3301. 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 can be conducted to verify correct detector positioning and coverage.

•For ATEX installations, the X3301 Flame 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 X3301 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 o i 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/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 mm2 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 X3301.

note

Refer to “Power Consumption” in the “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.

If disconnection of power is required, separate disconnect capability must be provided.

CAUTION

Installation of the detector and wiring should be performed only by qualified 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 or M10 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 "Specifications" 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 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.

3.Make the final sighting adjustments and use a 14 mm hex wrench to ensure that the mounting arm assembly is tight.

EOL Resistors (Not Used with EQP Model)

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 flameproof terminal compartment. Unused conduit entries shall be closed with suitable blanking elements.
