Page 8 FS20X Fire and Flame Detectors Product Overview The model FS20X™ fire and flame detector senses the ultraviolet and wideband infrared radiant energy of blackbody particulate and molecular emissions generated by both hydrocarbon and non-hydrocarbon flames and fires. The wideband spectral radiant energy wavelengths sensed by its four sensors span approximately 0.185 to 0.26 microns and 0.7 microns to 3.5 microns.
Page 9: Principle Of Operation
Built-in microprocessors use digital signal processing (DSP) to distinguish between radiant energy from a real fire and that from a false alarm source. Honeywell Analytics has developed and refined these complex proprietary and patented WideBand IR and UV algorithms for 30 years, beginning in 1981. These patented algorithms perform real-time DSP, and precisely analyze the signals in high-resolution frequency and time domains.

Page 14 Test Lamps Some manufacturers claim that their detectors do not need remote testing with an external test lamp because it tests itself. Even though Honeywell Analytics detectors also perform “through-the-window” self-testing, Honeywell Analytics, in compliance with NFPA 72 codes, has developed portable test lamps for end-to-end remote testing.
Page 15: Field Of View Restrictor
FS20X Fire and Flame Detectors Test lamp TL-2055 Model TL-2055 is designed for handheld testing of FSX detectors in hazardous locations. The test lamp, shown in Figure 4, is explosion-proof and carries Class I, Division 1 approval. It also is supplied with a universal, 110VAC/220VAC charger. Figure 4.
Page 16: Installation
FS20X Fire and Flame Detectors Installation Installation Practices For installations in a Hazardous Classified Area, consult the National Electrical Code Handbook, articles 500 through 517 for the proper installation practices. For locations outside the United States, observe local and regional regulations. CAUTION The detector’s metal conduit plug by itself will not provide a weathertight seal.
Page 17 ● Consult Honeywell Analytics for dimensional information on flameproof joint specifications. ● Verify that the detector is securely mounted, its window is clean, and it has an unobstructed view of the area of coverage (see “Installation Practices”...
Page 18: Mounting Instructions
FS20X Fire and Flame Detectors Mounting Instructions Consider the following guidelines when selecting a detector location: 1. Avoid areas containing radiant energy sources (e.g., radiant heaters, high intensity lamps, flare stacks, etc.) that would be near the detector’s field of view. 2.
Page 19 FS20X Fire and Flame Detectors Adaptor plate Mounting plate Figure 7. SM4 swivel mount 3. Provide the detector an unobstructed view of the threat area. Obstructions between the detector and a fire may prevent it from being detected. 4. Mount the detector in an area where temperatures will not exceed the specified operating temperature range (see “Environmental”...
Page 20: Opening The Detector
FS20X Fire and Flame Detectors Opening the Detector CAUTION Use a wrist strap connected to earth ground and follow other static protection procedures when handling connectors and wiring the electronics module to the detector. N OT I C E Do not touch the sensor windows on the front of the detector’s electronics module (see Figure 10).

FS20X Fire and Flame Detectors User-selectable Configuration Switches 1. The ten-pin DIP switch (SW1) is used to select a unique digital address (128 choices). 2. The eight-pin DIP switch (SW2) is used to select the detector’s sensitivity and relay options. 3.
Page 24: Detector Connections
FS20X Fire and Flame Detectors Detector Connections The electronics module has six-pin and ten-pin keyed, removable connectors with female screw terminal plugs. These connect to the two respective male connectors with analog, digital, and relay interfaces (see Figure 16). Use the ten-pin plug (J2) and connector for relay configurations.

Page 27 FS20X Fire and Flame Detectors Figure 21. Recommended wiring configurations Changing Detector Settings 1. Verify that the external 24 VDC power is turned off before connecting the detector. 2. After applying 24 VDC power, after tests (i.e., butane lighter, FSC test lamp, or test fires), or after resetting the detector, wait at least thirty seconds to allow its sensors to normalize to the spectral background conditions.
Page 28: Start-Up And Commissioning
After the detector is powered, thoroughly test is using a hand-held test lamp to ensure the detector has an unobstructed view of the threat area. Honeywell Analytics FSX detectors feature automatic electronics and internal software testing every three seconds. This includes a through-the-window test that verifies the cleanliness of the viewing window.
Page 29 “Test Lamps” on page 15. These are the only test lamps that can activate FSX detectors. Do not use them with other Honeywell Analytics detectors or with those of other manufacturers. 1. Disable the outputs (a full functional test includes activating the alarm outputs).
