Quick Start Guide 1.0 Quick Start Guide 1.1 Upon Receipt of Equipment All items shipped by General Monitors are packed in shock absorbing containers, which provide a considerable degree of protection against physical damage. When received, the contents should be carefully removed and checked against the enclosed packing slip. All subsequent correspondence with General Monitors must specify the equipment part number and serial number. 1.2 Choosing Detector Locations Several variables are involved in selecting the locations to install detectors to ensure proper flame detection. There are no hard and fast rules defining the optimum location. There are some general suggestions that should be considered in regard to particular conditions at the site where the unit(s) are being installed: 1.2.1 Detector Field of View Each Model FL3102 Flame Detector has a 120 maximum Cone of Vision. This Cone has its vertex at the center of the detector (see Figure 1). 1.2.2 Optical Sensitivity Range The distance at which the detector will respond to a flame is a function of the intensity of that flame. The maximum distance is 50 feet (15.2m) for a gasoline fire with a surface area of 1 square foot (0.92m 2 ). 1.2.3 Environmental Factors Mounting should be as free from shock and vibration as possible and convenient for visual inspection and cleaning. Detectors mounted in dirty atmospheric conditions will require more frequent inspection, cleaning, and sensitivity checking. Observe the ambient temperature range for the specific model (see Section 8.1.4 Environmental Specifications). For outdoor installations or other areas exposed to intense, direct solar radiation, the detector may reach temperatures well above specifications. For this condition, a cover for shade may be required to bring the detector temperature within specifications. As with any cover or object near-by, make sure the field-of-view of the detector is not obstructed. Avoid conditions of ice build up on the optical detector windows. Complete icing-over of the IR detector window can result in fault conditions. i
Quick Start Guide 1.3 Detector Installation The Model FL3102 Detector is an explosion proof assembly rated for use in Class I, Divisions 1 & 2, Group B, C & D, Class II, Group E, F & G, and Class III areas. The detector(s) should be mounted pointing downward so that dust/moisture will not accumulate on the IR windows. The detector(s) should be mounted in locations, which will inhibit people or objects from obscuring the detector s Cone of Vision. NOTE Before installing these units, please read the warning statement on page 13 of this manual. These units must have a conduit seal installed. Mounting hardware should be used as shown in Figures 2 and 3. NOTE The swivel (961-003) is rated for Class I, Div 1 & 2, Groups C & D. Use mounting bracket for Group B areas. The overall dimensions of the detectors and mounting hardware are shown in Figure 4. ii

The FAULT output configuration is normally energized and non-latching. This is the standard output configuration and it cannot be changed. The FAULT circuit will be activated during the time-out function, a low power or loss of power condition, and during a failed COPM check. During these conditions, the FAULT relays will de-energize and the analog output signal will drop to 0 ma (2mA for COPM Faults) for the duration of the FAULT. Fault Relay: TB2, Term 8 = FLT C = Fault Common Normally energized TB2, Term 9 = FLT 1 = Normally Open TB2, Term 10 = FLT 2 = Normally Closed The FAULT relay contact ratings are 8A @ 250VAC and 8A @ 30VDC. CAUTION For all relay connections see Figure 9. ix
Quick Start Guide 1.4.4 Alarm Reset Terminal TB1, Term 3 = RESET The RESET, when activated, returns a latched ALARM and/or WARN output, that is no longer valid, to its original state. For this RESET function, place one contact of a SPST normally open momentary switch to TB1 Terminal 3 and the other contact to DC COM (the detector s common). To activate, just press and release the switch. 1.4.5 Alarm Test Terminal TB1, Term 4 = ALARM TEST By connecting one contact of a SPST normally open momentary switch to TB1 terminal 4 and the other contact to DC COM (the detector s common) the user can test the alarm outputs of the Flame Detector by activating this switch for one to eight seconds depending on the alarm time delay setting. The Alarm Test will activate the WARN and ALARM relay outputs as well as the appropriate analog output. The Flame Detector will remain in this state until the switch is released. The latching WARN and/or ALARM will have to be RESET manually. The Autotest feature cannot be daisy chained between two or more FL3102 Flame Detectors. 1.4.6 Analog Output TB1, Term 5 = 0-20mA (Analog Output) The 0 to 20mA output is a current signal that corresponds to following: FAULT signal: COPM Fault signal: Ready signal: WARN signal: ALARM signal:.0 to 0.2mA 2.0 + 0.2mA 4.0 + 0.2mA 16.0 + 0.2mA 20.0 + 0.2mA The maximum analog output load is 600 ohms.

2.0 Introduction 2.1 General Description Model FL3102 Fire is a phenomenon of combustion. Combustion is the continuous chemical reaction of a reducing agent (fuel) and an oxidizing agent (oxygen, etc.) with the evolution of thermal energy (heat). Fire is usually manifested in heat (IR), smoke, light (visible), and flame (UV). Flame is the gaseous region of a fire where vigorous combustion chain reactions take place. These reactions emit radiation covering the Infrared, Ultraviolet and the Visible Spectral Regions. The General Monitors Model FL3102 is a Dual Frequency Infrared (DFIR) Flame Detector (Figure 14). The Model FL3102 detects the Infrared spectral regions of flame to produce a system, which is highly immune to false alarms caused by lightning, arc-welding, hot objects, and other sources of radiation. In addition, the FL3102 can see through most smoky type fires such as diesel, rubber, etc. The Model FL3102 has features that include: Compact unitized design. Continuous optical path monitoring. 0-20mA, alarm relays and MODBUS RTU-485 standard. Wide field of view. High false alarm immunity. Figure 14 Model FL3102 7
2.2 Principle of Operation 2.2.1 IR Flame Detector The Model FL3102 is a discriminating Dual Frequency Infra-Red Detector, which makes use of Infrared detectors for different IR wavelengths and characteristics. This combination provides a flame detection system, which is highly immune to false alarms. Incorporated in the IR circuitry is a flicker discrimination circuit. This permits the detector to ignore steady static IR sources such as hot objects. The inherent flickering of a flame provides the necessary modulation to activate the IR circuit. The Model FL3102 Flame Detector processes these IR signals with a microcomputer and produces the following outputs: 0 to 20 Milliampere signal. Immediate WARN relay contacts. Time delayed ALARM relay contacts. FAULT relay contacts. RS- 485 MODBUS RTU output. Optional: Redundant RS- 485 Modbus RTU output. (See Sections 3 & 4 for more information on detector outputs.)

2.2.2 COPM Circuitry A self- testing feature called Continuous Optical Path Monitoring (COPM) checks the optical path, the detector(s), and the related electronic circuitry once every minute. If foreign material impairs the optical path of the infrared detector for two consecutive checks, the unit will indicate FAULT. The optical FAULT outputs are a 2.0 ma signal, de-energizing of the FAULT relay, and RS-485 output signal (see Section 3.4 Terminal Connections). After a COPM FAULT, a COPM check is performed every ten seconds until the obstruction is removed. Then the COPM check will resume a once per minute check. WARNING Dirty or partially blocked windows can significantly reduce the detectors field of view and detection distance. NOTE Since the optical path is checked once per minute and it requires two check failures to produce a FAULT, it may take up to two minutes for the unit to detect an obstruction. 2.2.3 Alarm Test The Model FL3102 Flame Detector has a built-in Alarm Test feature. By connecting one contact of a SPST momentary switch to TB1 position 4 and the other contact to DC COM (see Section 3.4 Terminal Connections), the user can test the alarm outputs of the Flame Detector by activating this switch for one to eight seconds depending on the Alarm Delay Setting. The Flame Detector will immediately go into WARN and then into the time delayed ALARM. After one to eight seconds the Flame Detector will activate the ALARM. A latching WARN and/or ALARM will remain latched until manually reset. 2.2.4 Visual Indicators Two light emitting diodes (LED s) are visible through a window. LED s are provided for a visual indication that corresponds with the detectors outputs. The following blinking sequence indicates the operation condition: Time out (10 seconds when the unit is first powered) - Green and red LED s blinking alternately. Ready - Green LED that flashes off 1 second, every 10 seconds. WARNing - Slow blinking red LED with green LED on steady. ALARM - Fast blinking red LED with green LED on steady.

3.0 Installation 3.1 Upon Receipt of Equipment All items shipped by General Monitors are packed in shock absorbing containers, which provide a considerable degree of protection against physical damage. When received, the contents should be carefully removed and checked against the enclosed packing slip. All subsequent correspondence with General Monitors must specify the equipment part number and serial number. 3.2 Choosing Detector Locations Several variables are involved in selecting the locations to install detectors to ensure proper flame detection. There are no hard and fast rules defining the optimum location. There are some general suggestions that should be considered in regard to particular conditions at the site where the unit(s) are being installed: 3.2.1 Detector Field of View Each Model FL3102 Flame Detector has a 120 maximum Cone of Vision. This Cone has its vertex at the center of the detector (see Figure 16). 3.2.2 Optical Sensitivity Range The distance at which the detector will respond to a flame is a function of the intensity of that flame. The maximum distance is 50 feet (15.2m) for a gasoline fire with a surface area of 1 square foot (0.92m 2 ). 3.2.3 Environmental Factors Mounting should be as free from shock and vibration as possible and convenient for visual inspection and cleaning. Detectors mounted in dirty atmospheric conditions will require more frequent inspection, cleaning, and sensitivity checking. Observe the ambient temperature range for the specific model (see Section 8.1.4 Environmental Specifications). For outdoor installations or other areas exposed to intense, direct solar radiation, the detector may reach temperatures well above specifications. For this condition, a cover for shade may be required to bring the detector temperature within specifications. As with any cover or object near-by, make sure the field-of-view of the detector is not obstructed. Avoid conditions of ice build up on the optical detector windows. Complete icing-over of the IR detector window can result in fault conditions. 10
3.3 Detector Installation The Model FL3102 Detector is an explosion proof assembly rated for use in Class I, Divisions 1 & 2, Group B, C & D, Class II, Group E, F & G, and Class III areas. The detector(s) should be mounted pointing downward so that dust/moisture will not accumulate on the IR windows. The detector(s) should be mounted in locations, which will inhibit people or objects from obscuring the detector s Cone of Vision. NOTE Before installing these units, please read the warning statement on page 13 of this manual. These units must have a conduit seal installed. Mounting hardware should be used as shown in Figures 17 and 18. NOTE The swivel (961-003) is rated for Class I, Div 1 & 2, Groups C & D. Use mounting bracket for Group B areas. The overall dimensions of the detectors and mounting hardware are shown in Figure 19. 11

3.4 Terminal Connections All wire connections are made through the ¾ NPT openings in the Base Assembly to the terminal block (See Figure 22). The Terminal Block is located on the Base Assembly (See Figure 23) and accepts 12 AWG to 22 AWG stranded or solid-core wire. Each wire should be stripped as shown in Figure 20. Figure 20 Wire-Strip Length To connect the wire to the Terminal Block, insert the conductor into the connection space as shown in Figure 23 and tighten the corresponding screw terminal. Figure 21 Detector Housing and Base 15
Figure 22 Terminal Block Operation There are twenty possible terminal connections. On this and the following pages is a description and specification for each connection. 3.4.1 Alarm Relay TB2, Term 2 = ALARM C TB2, Term 3 = ALARM 1 TB2, Term 4 = ALARM 2 Description: The connections are to the SPDT ALARM relay. ALARM output is time delayed for 2, 4, 8, or 10 seconds. This time delay can be set by RS-485 or DIP-switch, (see Section 3.5). The ALARM output can be normally energized or normally de- energized, latching or non- latching, and these options are also set via RS-485 or by DIP-switch. (See Section 3.5, Switch Selectable Options) Alarm Relay: TB2, Term 2 = ALM C = Alarm Common Normally de-energized TB2, Term 3 = ALM 1 = Normally Closed TB2, Term 4 = ALM 2 = Normally Open Normally energized TB2, Term 3 = ALM 1 = Normally Open TB2, Term 4 = ALM 2 = Normally Closed The ALARM relay contact ratings are 8A @ 250VAC and 8A @ 30VDC. 16
CAUTION For all relay connections see Figure 24. Figure 23 Terminal Connections 3.4.2 Warning Relay TB2, Term 5 = WARN C TB2, Term 6 = WARN 1 TB2, Term 7 = WARN 2 Description: These connections are to the SPDT WARN relay. The WARN output is immediate on the Model FL3102. The WARN output can be normally energized or normally de-energized, latching or non-latching. These options are also set via RS-485 or by a DIP-switch. (See Section 3.5 Switch Selectable Options) Warning Relay: TB2, Term 5 = WARN C = Warning Common Normally de- energized TB2, Term 6 = WARN 1 = Normally Closed TB2, Term 7 = WARN 2 = Normally Open Normally energized TB2, Term 6 = WARN 1 = Normally Open TB2, Term 7 = WARN 2 = Normally Closed 17

Figure 24 Relay Contacts 3.4.3 Fault Relay TB2, Term 8 = FLT C TB2, Term 9 = FLT 1 TB2, Term 10 = FLT 2 Description: These connections are to the SPDT FAULT relay. The FAULT output configuration is normally energized and non-latching. This is the standard output configuration and it cannot be changed. The FAULT circuit will be activated during the time-out function, a low power or loss of power condition, and during a failed COPM check. During these conditions, the FAULT relays will de-energize and the analog output signal will drop to 0 ma (2mA for COPM Faults) for the duration of the FAULT. Fault Relay TB2, Term 8 = FLT C = Fault Common Normally energized TB2, Term 9 = FLT 1 = Normally Open TB2, Term 10 = FLT 2 = Normally Closed The FAULT relay contact ratings are 8A @ 250VAC and 8A @ 30VDC. CAUTION For all relay connections see Figure 24. 18
3.4.4 Alarm Reset Terminal TB1, Term 3 = RESET The RESET, when activated, returns a latched ALARM and/or WARN output, that is no longer valid, to its original state. For this RESET function, place one contact of a SPST normally open momentary switch to TB1 Terminal 3 and the other contact to DC COM (the detector s common). To activate, just press and release the switch. 3.4.5 Alarm Test Terminal TB1, Term 4 = ALARM TEST By connecting one contact of a SPST normally open momentary switch to TB1 terminal 4 and the other contact to DC COM (the detector s common) the user can test the alarm outputs of the Flame Detector by activating this switch for one to eight seconds depending on the alarm time delay setting. The Alarm Test will activate the WARN and ALARM relay outputs as well as the appropriate analog output. The Flame Detector will remain in this state until the switch is released. The latching WARN and/or ALARM will have to be RESET manually. The Autotest feature cannot be daisy chained between two or more FL3102 Flame Detectors. 3.4.6 Analog Output TB1, Term 5 = 0-20mA (Analog Output) The 0 to 20mA output is a current signal that corresponds to following: FAULT signal: COPM Fault signal: Ready signal: WARN signal: ALARM signal:.0 to 0.2mA 2.0 + 0.2mA 4.0 + 0.2mA 16.0 + 0.2mA 20.0 + 0.2mA The maximum analog output load is 600 ohms. Cable Requirements: For interfacing with 250 ohm input impedance devices, the following maximum cable lengths apply (maximum 50 ohm loop): AWG FEET METERS 14 9000 2750 16 5800 1770 18 3800 1160 20 2400 730 22 1700 520 Figure 25 Maximum Cable Lengths for 250 Ohm Input 19

The RS-485 connection is used to either query the unit s status or to configure the unit. See Section 7.0 for detailed information on Modbus RTU protocol. NOTE If redundant RS-485 output is ordered, then the 0-20mA output is not available and the wiring terminals are: TB1, Term 5 = DATA2+ TB1, Term 6 = DATA2-3.4.9 Chassis Ground TB2, Term 1 = CHAS GND This connection is available for use in wiring that requires a connection to chassis ground. In general, all cable lengths specified are maximum values. Good design practices dictate cable lengths conservatively shorter than the maximum values given. 20
3.5 Switch Selectable Options All settings on the Model FL3102 are done via a DIP-switch on the Power/Relay board or via RS-485 (overrides switch settings). To set these options, remove the detector head from the Base Assembly and locate the DIP-switch (see Figure 27). On the DIP-switch, ON/CLOSED means the switch is pushed in on the side labeled ON or CLOSED (opposite the OPEN side). OFF/OPEN means the switch is pushed in on the side with the number corresponding to the switch position or the side labeled OPEN. (Refer to the tables in Figure 28 for the switch assignments.) The settings for the WARN and ALARM outputs have been covered in section 3.4. The time delay specifies the amount of time a WARN condition persists before an ALARM condition will occur.

4.0 Maintenance 4.1 General Maintenance Once correctly installed, the unit requires very little maintenance other than regular sensitivity checks and cleaning of the lenses. General Monitors recommends that a schedule be established and adhered to. Model FL3102 NOTE The removal of particulate matter and any film buildup on the lenses and light rods is necessary to ensure proper sensitivity of the system. It is recommended that the window and light rods be cleaned at least every 30 days or more often if the detector is located in a particularly dirty environment. 4.2 Cleaning the Lenses A clean, soft, lint-free cloth, tissue or cotton swab should be used to apply the cleaning solution. Do not touch the lenses or light rods with fingers. 1. Wet the window with the solution. 2. Rub with a dry, unsoiled cloth until the window is clean. 3. Completely dry the window. 4. Repeat steps a, b and c for the light rods. (See figure 29). Take care only to clean the uncoated (non - aluminum) areas of the light rods. WARNING Dirty or partially blocked windows can significantly reduce the detectors field of view and detection distance. DO NOT USE A COMMERCIAL GLASS CLEANER OTHER THAN INDUSTRIAL STRENGTH WINDEX with Ammonia D The lenses are not glass. One IR lens material is quartz and the other IR lens material is sapphire. The cleaning solution should be General Monitors P/N 10272-1 (Industrial Strength Windex with Ammonia D). Figure 29 IR Windows 22
4.3 Sensitivity Check To verify that each detector is functioning correctly, a General Monitors Test Lamp and/or the ALARM TEST function (see section 2.2 Principle of Operation - Alarm Test) should be used. See Section 8.3, Spares & Accessories, for details on test lamps. 4.4 Storage These Flame Detectors should be stored in a clean, dry area and within the temperature and humidity ranges quoted in Section 8.1.4 Environmental Specifications. 23
5.0 Troubleshooting 5.1 Trouble Shooting Chart Model FL3102 This section is intended to be a guide in correcting problems, which may arise in the field.

7.5 Exception Responses and Exception Codes Model FL3102 Baud Rate (bps) In a normal exchange, the master device sends a query to the FL3102. The FL3102 receives the query and returns a normal response to the master. If a normal communications error occurs, there are 4 possible responses from the FL3102: 1. If the FL3102 does not recognize the query due to a communications error, then no response is returned from the FL3102 and the master device will eventually process a timeout condition for the query. 2. If the FL3102 receives the query, but detects a communication error (CRC, etc.), then no response is returned from the FL3102 and the master device will eventually process a timeout condition for the query. 3. If the FL3102 receives the query without a communications error, but cannot process the response to the master within the master's timeout setting, then no response is returned from the FL3102 and the master device will eventually process a timeout condition for the query. In order to prevent this condition from occurring, the typical response times for the FL3102 are listed below: Query From Master (msec) Unit Response Delay Time to Query (msec) Response From Unit (msec) Master Response Delay Time Between End of Unit Response and Next Master Query (msec) Total Response Time (msec) 19.2K 4 4 4 100-120* 112 132 9600 8 5 8 100-120* 121 141 4800 16 6 16 100-120* 138 158 2400 32 8 32 100-120* 172 192 Figure 37 Typical Response Times for FL3102 NOTE* - Master Response Delay Time is dependent on the speed of response for the Master (DCS, PLC, etc.) Cycle Time can be significantly reduced with a faster Master. The 100ms Delay Time was taken from a typical Master, using a PC with Intellution Industrial Control Software, which was set at the minimum poll time. 4. If the FL3102 receives the query without a communications error, but cannot process it due to reading or writing to a non-existent or illegal FL3102 Function Code, Illegal Command Starting Address or Register Address, or Illegal Data Value, then the FL3102 will return an exception response message informing the master of the error. The exception response message has two fields that differentiate it from a normal response, which is explained in Section 7.5.1. 30
7.5.1 Exception Responses Byte MODBUS Range Referenced to FL3102 1 st Slave Address 1-247* (Decimal) FL3102 ID (Address) 2 nd Function Code 83 or 86 (Hex) MSB is set with Function Code 3 rd Exception Code 01-06 (Hex) Appropriate Exception Code (See below) 4 th CRC Lo 00-FF (Hex) CRC Lo Byte 5 th CRC Hi 00-FF (Hex) CRC Hi Byte Figure 38 Exception Responses 7.5.1.1 Function Code Field In a normal response, the FL3102 echoes the function code of the original query in the function code field of the response. All the Function Codes have a most-significant bit (MSB). In an exception response, the FL3102 sets the MSB of the function code to a one (1). With the function code s MSB set, the master can recognize the exception response and can process the data field for the exception code from the FL3102 response message. 7.5.1.2 Exception Code Field In a normal response, the FL3102 returns data and status in the data field, which was requested in the query from the master. In an exception response, the FL3102 returns an exception code in the data field, which describes the FL3102 condition that caused the exception. Below is a list of exception codes that are supported by the FL3102: Code Name Description 01 Illegal Function The function code received in the query is not an allowable action for the FL3102. 02 Illegal Data Address The data address received in the query is not an allowable address for the FL3102. 03 Illegal Data Value A value contained in the query data field is not an allowable value for the FL3102. 04 Slave Device Failure An unrecoverable error occurred while the FL3102 was attempting to perform the requested action. 05 Acknowledge The FL3102 has accepted the request and is processing it, but a long duration of time will be required to do so. This response is returned to prevent a timeout error from occurring in the master. 06 Device Busy The FL3102 is engaged in processing a longduration program command. The master should retransmit the message later when the slave is free. Figure 39 Exception Code Field 31

A write command changes the state of the EEPROM Override bit. When the EEPROM Override bit is enabled, the options for the Detector Sensitivity, Relay Delay, Relay Latching/Non-Latching and Relay Energized/Non-Energized features are now controlled by the data stored in the EEPROM and are no longer controlled by the 8-position DIP-switch located on the bottom of the Power/Relay Board. When the EEPROM Override bit is disabled the options are under the control of the 8- position DIP-switch. The EEPROM Override bit is located in the LSB of the Low Data Byte and the High Data Byte is not used. 36
Function Bit (LSB) Access Enable 1 Read/Write Disable 0 Read/Write Figure 44 EEPROM Override EXCEPTION - If an EEPROM error occurs, then the Exception Code 04 (Slave Device Failure) is returned. NOTE - By grounding the ALARM TEST input during the first 10 seconds of the 2 minute power-up cycle, the FL3102 will Disable the EEPROM Override and set the Bit = 0, enabling the 8-position Dip-switch. The red and green LED s will flash simultaneously while the ALARM TEST input is grounded. The EEPROM Override bit will be set to zero and the Dip Switch enabled when the red and green LED s flash alternately after approximately10 seconds, at which time the ALARM TEST input can be released from ground. 7.7.9 Options A read returns the status of the settings for the Detector Sensitivity, Relay Delay, Relay Latching/Non-Latching and Relay Energized/Non-Energized features either from the Options DIP-switch or the EEPROM depending on the setting of the EEPROM Override bit listed above. A write command changes the settings for the EEPROM only when the EEPROM Override bit is set. EXCEPTION - If an attempt to change the EEPROM Options is made while the EEPROM Override bit is not set, then the unit shall return an Exception Code 03 (Illegal Data Value). EXCEPTION If an EEPROM write error occurs, then the Exception Code 04 (Slave Device Failure) is returned. These Functions are indicated on the Low Data Byte and the High Data Byte is not used. 37

A write changes the address to the requested address. The range of the address is 1 to 247 (01 to F7 Hex). After the address has been changed to the slave unit, the MODBUS communications will cease because the address has changed; therefore the master will have to change its query address to the slave s new address in order to restart the communications. EXCEPTION - If the EEPROM write error occurs, then the Exception Code 04 (Slave Device Failure) is returned. NOTE - By grounding the RESET input during the first 10 seconds of the 2- minute power-up cycle, the FL3102 Address will default to 1. The red and green LED s will flash simultaneously while the RESET input is grounded. The address will be set to a default of 1 when the red and green LED s flash alternately after approximately 10 seconds, at which time the RESET input can be released from ground. 7.7.11 Comm 1 Baud Rate A read returns the baud rate of the FL3102. A write changes the baud rate to the requested baud rate. After the baud rate has been changed to the addressed unit, the MODBUS communications will cease because the baud rate has changed; therefore the master will have to change its baud rate to the slave s new baud rate in order to restart the communications.

8.3.2 TL103 Test Lamp Due to the advanced discrimination in the Model FL3102, the Model TL103 Test Lamp was developed. The General Monitors TL103 Test Lamp is a battery operated, rechargeable, test source specifically designed to test General Monitors IR Flame Detection Systems. It consists of a high-energy broad band radiation source which emits sufficient energy in the Infra-Red spectra to activate the IR detector. To simulate a fire, the test lamp automatically flashes at one of three DIP-switch selectable rates. The Model TL103, rated explosion proof, is CSA certified for use in Class I, Division 1, Groups C and D areas. The test lamp operates on internal lead-acid batteries which, when fully charged, will operate continuously for 25 to 30 minutes. An internal circuit will prevent operation when the batteries are low. Operating Instructions It is always important to begin a series of flame detector checks with a fully charged TL103. Stand within 10 feet (FL3102) from the unit to be tested and aim the TL103 directly into the detector windows. Press the ON button and be sure the high intensity pulsing beam strikes the detector face squarely. Shaking the lamp from side to side or up and down will increase the simulation of flame flicker, and improve the response of the flame detector to the lamp. If the system is operating normally, the control module will go into a WARNing condition after a few flashes of the Test lamp. If the lamp remains ON for the period set by the Time Delay Adjustment, the controller will go into ALARM. To conserve charge, do not operate the Test Lamp longer than is necessary to test each channel. When the battery level drops below the level required to maintain the proper intensity of the lamp, an internal low voltage circuit will shut the lamp off until the battery has been recharged. Recharging Instructions NOTE Charging must be carried out in a non-hazardous area. The charging receptacle is located inside the housing adjacent to the ON button. To gain access, it is necessary to unscrew the knurled plug from the body of the unit. The plug is secured to the ON button by a safety strap to keep it from being lost. Insert the charging plug into the receptacle. Complete recharging takes fourteen hours, minimum. IMPORTANT: Replace the knurled plug after charging is complete. It is recommended that the TL103 be kept on charge when not in use to prevent excessive battery discharge. The batteries may be charged an average of 500 times and the battery pack is replaceable. 8.3.3 Mounting Swivel / Union A mounting swivel and union are available to connect ¾ conduit into the base of the Model FL3102. The swivel design allows for optical alignment adjustments for the Model FL3102 when using rigid conduit. 48
NOTE Swivel is only rated for Class I, Div 1 & 2, Groups C & D areas. For Group B areas, use mounting bracket. 8.3.4 Mounting Bracket A mounting bracket is available to mount the FL3102 to a wall, pole, etc. The mounting bracket design allows for optical alignment adjustments for the Model FL3102 when installed to a fixed installation. 8.3.5 Optical Air Guard An optical air guard is available for applications such as paint spray booths, which require a method to keep detector optics clean. This air guard mounts at the front of the FL3102 and has a connection for shop air. The air when turned on creates an air wall to keep optics clean. 49
