1. PRODUCT DESCRIPTION
1.1 Introduction
All versions of the Model 3100 Flame Detector Se­ries utilize Ultraviolet, Infrared and V isible spectrum to provide continuous and reliable flame detection. The microprocessor in the Model 3100 is config­ured with state-of-the-art fire algorithms and con­tinuously analyzes the data from the sensor array for individual intensity values, change of intensity values, relationship of intensity values and frequency signature correlations. Each algorithm is designed to recognize a different type of flame signature from the detectors while rejecting common false sources. When the conditions of any one of the several fire algorithms are met the Model 3100 declares a fire.
1.2 Fault Diagnostics
The micro-processor is also continuously perform­ing system tests looking for any faults which would impair its ability to accurately detect a flame and declare an alarm. The systems being tested include: input power, sensor circuits, relay circuits, and sev­eral other internal systems. The Model 3100 Flame Detector also performs a through the lens test of the sensor and lens systems. All faults are recorded in non-volatile memory and may be retrieved by a trained technician.
1.3 Configuration
The Model 3100-01 has a Fire Relay and a Fault Relay which may be connected as normally open or normally closed contacts. Models 3100-02, -03, ­04, and -05 have in addition to the Fire and Faults relays a Fire Verify system and an Auxiliary Fault system. The Fire Verify system adds a “field ad­justable” level of certainty to the declaration of a verified fire. The Auxiliary Fault system will acti­vate the Aux. Relay for the Lens Test fault. This allows a separate indication for the most common fault (a dirty lens). A technician can know immedi­ately what is wrong and how to fix it (i.e. wipe the lens) without reading codes, consulting manuals, or wading through a process of complex diagnostics. The 3100-06 has an industry standard 4-20 mA out­put and no relays.
The Model 3100 detector is mounted in a NEMA 4X explosion proof housing, rated for Class I Divi­sion 1 & 2 Groups B, C, D, Class II Division 1 & 2 Groups E, F, G, and Class III locations. The elec­tronics are mounted inside an aluminum cup to pro­tect the electronics during installation. All switch settings and indicators are located on the front of the Model 3100 detector module allowing field ad­justments to be made without removing the detec­tor module from the housing.
Each Model 3100 detector is calibrated and tested to respond to a 1 square foot Kerosene fire at 80 feet with a Field-of-View of 120°. The Model 3100 detector has four sensitivity settings and six verify levels.

2. OPERATION
2.1 General
When the Model 3100 Flame Detector is powered up, the microprocessor checks the configuration switch settings and configures the detector. The mi­croprocessor then runs a full series of self tests. After the self test process is complete and all tests are passed, the detector is ready to detect a fire.
All modes of operation are indicated by two LEDs located on the front of the detector. Normal Mode is indicated by a brief flash of the LEDs every 8 seconds. With the device in Normal Mode it is constantly monitoring the environment and ready to detect a fire.
When a fire is detected the flame detector will acti­vate the Fire Relay and turn on both LEDs. If the device is configured for “Latching” Mode the de­vice will remain in Alarm Mode until power is re­moved. In “Fire Following” Mode the Fire Relay will reset when the Fire Probability Algorithm de­termines there is no longer a fire.
The self test system is continuously monitoring the internal systems. When a fault is detected the Fault Relay is de-energized. In Fault Mode the LEDs
will flash a code indicating the type of fault. A fault indication may mean the device is unable to detect a fire or that a device has become unreliable. (i.e. a “Voltage Low” fault) For most faults the detector will return to Normal Mode when the fault condi­tion is corrected.
The Model 3100 Series comes in several versions. The basic version 3100-01 does not have the Verify or the Auxiliary Relay systems. The enhanced Mod­els 3100-02, -03, -04 and -05 have the Verify and Auxiliary Relay systems. These versions represent the different configurations (Normally Open or Closed contacts) of the V erify and Auxiliary Relays. The Auxiliary Relay provides a separate relay out­put for the Lens Test Fault. The Verify system is activated when a fire is declared. A V erified Fire is declared when the conditions of the Verify Fire Al­gorithm are met. All other functions are the same as the basic Model 3100-01.
The 3100-06 does not have relay outputs. It uses a 4-20 mA current circuit. The detector's status de­termines the amount of current flow through the circuit.

2.2 Field-of-V iew (See Figure 2-1)
Optical Flame Detectors must be able to “see” the fire to declare an alarm. Any obstruction between the detector and the threat area will impair the de­tectors ability to cover the threat area. An obstruc­tion is anything that is not transparent to the sensor elements of the detector. UV sensors and some types of IR sensors cannot see through glass or plas­tics. The 3100 series of Flame Detectors has a 120° Field of V iew .
When covering a large area the detectors should be located to provide overlapping fields of view to in­sure complete coverage.
2.3 Range
The size of fire and type of materials which consti­tute the threat will affect the detector’s range. Dif­ferent materials produce different amounts of the radiant energy used by the detector to “see” the fire. Also, the range of the detector is a function of the fire size. Using the square of the distance rule, if the device will detect a one sq. ft. fire at 60 feet, to detect a 1/4 size fire (aprox. 6 sq. in.) the devices must be within 30 feet. The Model 3100 Detector is optimized to a 1 sq. ft. Kerosene fire at 80 feet with the sensitivity settings set to maximum sensi­tivity .
2.4 Environment
All optical flame detectors sense radiant energy at some frequency or frequencies within their Field­of-View. Any source which radiates energy at the same frequency or frequencies used by the detector
SW9 SW8 SW7 SW6
to sense a fire may impact the detector’s ability to “see” the fire. Care should be taken to minimize radiant energy sources within the detectors Field­of-View. Because of the variety of environments and conditions, a factory trained technician or quali­fied P.E. should be consulted before deciding on the location of devices. The Model 3100 Detector uses an Ultraviolet sensor (180 - 260 nanometers), an Infrared sensor (.715 - 3.5 microns), and a Vis­ible sensor (480 - 560 nanometers).
2.5 Configuration (See Figure 2-2)
All of the 3100 Series models have field adjustable configuration switches located on the front face of the detector. The factory settings are shown in italic text. The enhanced models have additional con­figuration options for the Verified Fire.
2.5.1 Sensitivity
All versions have several sensitivity settings available. The sensitivity settings are 20, 40, 60, and 80 feet. Each setting is optimized to alarm on a 1 sq. ft. Kerosene fire within 5 seconds. Switches 1 and 2 control the sensi­tivity. The factory default is 80 feet. (SW1
and SW2 are off.)
Note: Different fuels emit energy at different rates. For example; a fire involving fuel oil does not emit energy at the same rate as gaso­line. Consequently, the Model 3100 will be able to respond to a gasoline fire at a little greater distance than it will to a fuel oil fire. Similary, a fire involving acetone will be seen at a greater distance than one involving gaso-
line.

2.5.2 Verify Control
The Enhanced Model 3100-02, -03, -04, ­05 and -06 have the Verified Fire function. The Verify Control switches allow the user to select the verify level, disable the verify function, or make the Verify Relay operate in parallel with the Fire Relay. The verify function in enabled when the detector de­clares an alarm. The verify level sets the degree of certainty required to declare a veri­fied fire. The lowest level (1) is the lowest certainty (fastest) and the highest level (6) is the greatest certainty (slowest) of a fire. The verify function enables an algorithm which evaluates the fire signature over time to de­termine the degree of certainty. When the degree of certainty exceeds the level set by the configuration switches a Verified Fire is declared and the Verify Relay is energized. Switches 3, 4, and 5 control the verify func­tion. The factory default is verify disabled
and set to level 0. (SW3, SW4 and SW5 are off.)
2.5.3 Latching Control
The latching controls allow the detector or individual relay outputs to be set to “Latch­ing” or “Fire Following”. “Latching” causes the relay to stay energized until power is re­moved from the detector. “Non-latching” al­lows the relay to reset (de-energize) when a flame is not present for a short period of time.
For the detector to be set to "Non-latching" both Fire Output and Verify Output must be set to "Non-latching". If either the fire out-

Mounting Screw
put or the verify output is set to "Latching" then the detector will be set to "Latching".
When the detector is set to "Latching" the LED's will indicate an alarm until the device is reset regardless of the fire or verify relay output settings.
The Verify Relay is automatically configured as “Latching” if the Fire Relay is set to “Latch­ing”. SW6 sets the Fire Relay Output, SW7 sets the Verify Relay Output and SW8 sets the Detector Mode. To set the detector to "Non-latching", SW6, SW7 and SW8 must be set to "Non-latching. The factory defaults
are “Latching” (SW6 and SW7 ar e off.)
2.5.4 Other Configuration Switches
The last configuration switch (SW9) must be in the off position. The factory default set-
ting is off.
2.6 LED operation (See Figure 2-3)
The status of all versions of the flame detectors can be determined from the LEDs located behind the lens on the front of the detector. The LEDs will flash at intervals or remain on to indicate the detec­tors status. (Fault Mode, Normal Mode, Alarm Mode, Verified Fire Mode, and on power up the Configuration Settings).
2.6.1 Power Up
At power up all versions of the flame detec­tor will begin flashing the LEDs. The LEDs will flash 8 consecutive patterns which indi­cates the positions of the configuration switches. Each pattern indicates the position
Page: 4
Model 3100 Series Flame Detector (11/04)
Instruction Manual
Figure 2-4: Model 3100 Series Detector Module (Back)
(“on” or “off”) of a switch (SW1-SW8). The first flash pattern indicates the position of the first switch (SW1), with each consecu­tive flash indicating the position of the next switch in order. The flash pattern is as fol­lows: only one LED “on” indicates a switch in the “off” position, both LEDs “on” indi­cates a switch in the “on” position. The po­sition of SW9 is not indicated. If SW9 is in the “on” position the detector will power up in fault mode.
2.6.2 Normal
In Normal Mode the LEDs will flash briefly every 8 seconds. Whenever the device is in any other mode the “flash every 8 seconds” is suspended until the detector returns to Normal Mode.
2.6.3 Fire
When any version of the Model 3100 de­clares a fire, both LEDs will come “on” and stay “on”. If the detector is set to "Latching" the LED's will remain "on" and stay "on" until the detector is powered down. If the detector is set to "Non-latching" the LED's will reset to "Normal Mode" when the fire is no longer being detected. If the Verified Fire is declared (Verify Fire is only on the En­hanced Models) the LEDs will blink “off” briefly every second. If the detector is set to "Latching" the LED's will remain in this state until the detector is powered down.
2.6.4 Fault
When the detector has power and is in Fault Mode LED1 (the left LED when facing the detector with the configuration switches be­low the LEDs) will be on for 5 seconds while the LED2 (the right LED) will be off see Table B.4 on page 12. The LED will turn "off" and LED 2 will begin flashing 1/2 sec­onds "on" and 1/2 second "off" a number of times. The number of times LED2 flashes indicates the type of fault. This cycle is re­peated until the fault is corrected. Only the highest number fault is indicated. Once a fault is corrected the next highest level fault will be indicated until all faults are cured. Except for fault level 2 and 3, a fire indica­tion will override a fault indication. The de­tector is disabled if a fault 2 or 3 is indicated.
2.7 Relay operation (See Figure 2-4)
The Model 3100-01 has two relays, the enhanced Models 3100-02, -03, -04 and -05 have four relays. The function of the Fire and Fault Relays is the same on all models. The Verify Relay and Aux. Relay is only available on the enhanced models. All relay connections are made at the connectors lo­cated on the back of the flame detector module.
2.7.1 Fire Relay
The Fire Relay will energize whenever the detector declares a fire. Depending on the configuration setting, the relay will: “Latch-

Instruction Manual
ing” - remain energized until power is re­moved, ”Fire Following” - de-energize a short time after the fire is no longer detected. The “J2” connector provides connections for both normally open contacts and normally closed contacts on the Fire Relay .
2.7.2 Fault Re lay
The Fault Relay is a normally energized re­lay . It will de-energize when a Fault occurs. This means the detectors Fault Relay is in the “Fault” state when the detector has no power, and remains in the “Fault” state until the detector is powered up and operating nor­mally. The “J4” connector provides both normally open contacts and normally closed contact on the Fault Relay .
2.7.3 Verify Relay
The Verify Relay will energize when a “V eri­fied Fire” is declared. Depending on the con­figuration the relay will: “Latching” - remain energized until power is removed, “Fire Fol­lowing” - de-energize a short time after the fire is no longer detected. Further, the “Verify Control” configured to Level 0 will disable the V erify Relay , and Level 7 causes the Verify Relay to operate in parallel with the Fire Re­lay. The connector labeled “Verify In” and “Verify Out” provides connections for nor­mally open contacts on the 3100-02 and 3100­04 or normally closed contacts on the 3100­03 and 3100-05. The configuration of Nor­mally Open or Normally Closed contacts is fixed and can only be changed by the fac­tory.
3100-02 and 3100-05 models. The configu­ration of Normally Open or Normally Closed contacts is fixed and can only be changed by the factory .
2.7.5 4-20 mA Operation
The 3100-06 uses a 4 to 20 mA current draw circuit to indicate Fault, Fire, Verify Fire and Normal Mode. The current draws are as fol­lows:
Fault Mode: 0 mA Normal Mode: 4 mA Alarm Mode: 12 mA V erify Mode: 20 mA The 4-20 circuit is connected across the J2
connector at contact 6 and 7 where connec­tion 6 is the negative side and connection 7 is the positive side. Additionally, a jumper be­tween contacts 7 and 8 must be made.
2.7.4 Auxiliary Fault
The Aux. Relay is energized whenever the detector fails the “Lens Check” test. This fault indicates the detectors inability to “see” a fire. Normally , cleaning the lens will clear this fault. Because a dirty lens is the most common type of fault, a separate indicator connected to this relay will simplify mainte­nance. The connector labeled “Aux In” and “Aux Out” provides connections for Normally Open contacts on the 3100-03 and 3100-04 models or Normally Closed contacts on the

3.0 INSTALLATION
3.1 General Precautions
All wiring and installation must be done in accor­dance with the NFP A 70 and 72 standards and must comply with any codes specific to the application or location. Contact the local authority having juris­diction and the company safety engineer for infor­mation on codes which may apply .
3.2 Housing and Conduit
3.2.1 Mounting the Housing
The housing is mounted by using the two
0.3” diameter holes located in ears on the back of the housing. The two conduit holes located on the side of the housing are not to be used for mounting. The detector should be mounted securely to a flat surface. The mounting location must be strong enough to support the detectors 3 lb. weight. Although the detector is not vibration sensitive the de­tector should not be exposed to excessive vi­bration. "(The detector has been tested to meet the vibration standard set in FM’s Ap­proval Standard Class 3820, Sept. 1979. (.022" displacement, 10 Hz to 30 Hz sweep cycled at 2 cpm for 4 hours)"
3.2.2 Installing the Conduit and Wiring
Mount a “Seal Off” at the housing into the 3/4” NPT conduit(s) located on either side of the housing. Connect the conduit to the “Seal Off”. If one of the conduit openings is not used insert a sealing plug into the unused opening. Run the wires through the conduit, “Seal Off”, and into the housing. The ends of the wire should extend several inches (at least 2” to 4”) beyond the front of the hous­ing base.
3.3 Connection (See Appendix C for information regarding connection to various systems)
All connections are made on the back of the Model 3100 Flame Detector Module. Remove the housing cover from the housing base. Loosen the two slot­ted head captive screws located on the top of the PC board. Lift the Detector Module out of the housing base. Strip and connect the wires to the connectors located on the back of the Detector Module.
3.3.1 Power
Power for the 3100-01, -02, -03, -04 and ­05 flame detector is connected to the J5 con­nector labeled “Power”. Connect the nega­tive wire to PIN 1. Connect the positive (24 VDC) wire to PIN 4.
Power for the 3100-06 detector connected to the J2 connector. Connect positive wire at 4. Connect negative wire at pin 1. Pins 2 and 3 should be left open.
3.3.2 Fire Relay
The Fire Relay has two internal connection points. Either or both may be used. The Fire Relay connector, labeled “FIRE”, has connection points for Normally Open, Nor­mally Closed, and Common. The Normally Open connections are labeled “Open”, the Common contacts are labeled “Com”, and the Normally Closed contacts are labeled “Closed”.
3.3.3 Verify Relay
The Verify Relay has two internal connec­tion points. Either or both may be used. The Verify Relay connector is located between the Power and Fire relay connectors. The connection points are labeled “V erify In” and “V erify Out”. The V erify relay is configured for Normally Open (3100-02 and 3100-04), or Normally Closed (3100-03 and 3100-05) operation at the factory .
3.3.4 Fault Re lay
The Fault Relay connector is labeled “Fault”. The Normally Open connection is labeled “O”, the Common connection is labeled “Com”, and the Normally Closed connec­tion is labeled “C”. The Fault Relay is a normally energized relay. When the detec­tor has no power the Normally Open contact is closed and the Normally Closed contact is open.

Instruction Manual
3.3.5 Auxiliary Relay
The Auxiliary Relay connector is located be­tween the Power and Fire Relay connectors. The connection points are labeled “Aux In” and “Aux Out”. The Aux. Relay is config­ured for Normally Open (3100-03 and 3100-
04), or Normally Closed (3100-02 and 3100-
05) operation at the factory .
3.3.6 4-20 mA Connections
The 4-20 mA connections are connected at the J2 connections The positive side of the 4-20 mA circuit is connected to Pin 7 and negative side to Pin 6.
3.4 T esting
The Model 3100 Flame Detector uses ongoing self­test functions which will indicate a fault if any of the functions fail to pass. If an end to end test is required, a 1 sq. ft. pan with 1 inch of water and 1/ 8 inch of kerosene set at the max. distance set by the sensitivity settings may also be used. The detec­tor should alarm within 5 seconds of ignition of the fire.
The Model 3140 Flame Tester is also available. It simulates a UV/IR flame signature by emitting a steady state UV signal and modulated IR signal at a flicker frequency of 5 to 10 Hs.
NOTE: Because of the danger involved with
fire testing all safety precautions must be observed.
4.0 MAINTENANCE
The self-test functions eliminate the need for most regular maintenance procedures. If a detector indi­cates a fault, use the troubleshooting section of this document to correct the fault. Contact the local “authority having jurisdiction” or consult the local codes for any maintenance they may require for the type of system installed.
4.1 Lens Cleaning
The most common fault is a Lens T est Fault. Regu­lar cleaning of the Lens will eliminate this type of fault. The frequency will depend on the cleanliness of the area where the detector is installed and how the detector is mounted. A detector which is pointed down should require less cleaning than one that is pointed up. An area which has lots of oil particu­lates or dust will require more frequent cleaning than one that is oil and dust free. The frequency of the Lens T est Fault will indicate how often cleaning is necessary . If the device is failing the “Lens test” to often it may be necessary to install a dust shroud, realign the detector, or change the detectors mount­ing location.
To clean the lens: Wipe the lens surface and grill with a clean lint free cloth. If more extensive clean­ing is required use denatured or Isopropyl alcohol and a clean lint free cloth. Do not use any silica
based solvents. (Most common glass cleaners are silica based and should not be used to clean the lens.)

5.0 TROUBLESHOOTING
The flame detector has several built-in self test mechanisms which verify function and calibration. The following procedure covers most faults and problems which may occur during installation or during the course of normal operation.
5.1 No LED blink or erratic LED blink
With power connected to the detector the LEDs on the front of the detector module should begin blinking and blink about every 8 seconds. If they do not blink or blink in an abnormal fashion.
1. Remove the detector module from the hous­ing.
2. Check voltage at power connector (J5, Pin 1 and Pin 4) Pin 1 should be the connected to negative, and Pin 4 should be positive. Volt­age should be between 15 and 32 volts DC.
3. If Main power is correct and the detector is not indicating a fault. The detector module should be returned to the factory .
5.2 Detector Indicates Fault
Use the fault table (Table B.4, page 17) to deter­mine what type of fault is occurring and see ap­propriate section below to correct. If the correc­tive actions listed below do not correct the fault, contact the factory for further diagnostic instruc­tions or instructions on returning the detector for servicing. (Ref. 2.6.4) or repeat.
5.2.4 Fault T ype 4 - “Voltage Low Fault”
The input voltage is below 15 VDC. Re­move the Detector Module from the hous­ing. W ith the detector connected to power, measure the voltage between Pin 1 and Pin 4 on the Power connector (J5). The volt­age should be between 15 - 32 VDC. If the voltage is out of range check external wir­ing and power supply . There should not be more than 1 volt of AC ripple at 24 VDC. If the measured voltage is in range and there is no AC ripple, contact the factory for re­turn and service information.
5.2.5 Fault T ype 5 - “Photo Sensor Fault”
One of the Photo Sensors (Visible or IR) did not pass the internal self test. If both sensors are clean. The fault may be in the sensors or the self test circuit. Contact the factory for further diagnostic information.
5.2.6 Fault T ype 6 - “Relay Fault”
One of the Relay’s coil circuits is open. There is no corrective action. Contact the factory for return and service information.
5.2.7 Fault Type 7 - “V oltage High”
The Detector was exposed to an input volt­age above 32 Volts. There is no corrective action. Contact the factory for return and service information.
5.2.1 Fault T ype 1 - “Lens Test Fault”
Clean lens and grill per section 4.1. Reset the detector (remove and replace power). If the fault persists it may indicate a bad UV tube or UV source tube, factory ser­vice is required.
5.2.2 Fault T ype 2 - “Configuration Fault”
Dip Switch SW9 is “ON”. SW9 should be set to off for normal operation. Change SW9 to “OFF” and reset detector.
5.2.3 Fault T ype 3 - “Calibration Fault”
Calibration constants have been corrupted. Factory service is required.
Model 3100 Series Flame Detector (11/04)
5.2.8 Fault T ype 8 - “Temperature Out of Range”
The internal measured temperature was be­low -40° C or above 85° C. There is no corrective action. Contact the factory for return and service information.
5.3 Device appears to operate normally but will not alarm to a fire.
When the detector declares an alarm two things should happen. One, both the LEDs on the front of the detector should come on. Two, the fire re­lay should energize. Check the dip switch set­tings. (SW1, SW2, SW8, and SW9 should be off SW3 - SW7 have no impact.) Connect an ohm meter across the Fire relay connections at the “Fire” connector (Pin 1 and Pin 3 of J2). Run a fire test per section 3.4.

Instruction Manual
1. If the relay closes (0 ohms on the meter) and the LEDs come “on” the detector is operating normally. Check external alarm initiating cir ­cuit wiring.
2. If the relay closes and the LEDs remain off, or the relay remains open and the LEDs come on, the detector needs factory service.
3. If the relay remains open and the LEDs re­main off, contact the factory for further diag­nostic information.
