FS20X Fire and Flame Detectors www.acornfiresecurity.com 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.
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.
User can perform remote FS20X Detector diagnostics, real-time status, Real-Time Graphing (RTG™), SnapShot™ data recording, and downloading FirePics™ with Honeywell Analytics’ exclusive FSIM-2 USB Interface Unit and easy-to-use Windows-based PC Software. ● Designed to detect both hydrocarbon and non-hydrocarbon fires with a single FSX™...

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.
www.acornfiresecurity.com 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.
FS20X Fire and Flame Detectors www.acornfiresecurity.com 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.

● 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”...
FS20X Fire and Flame Detectors www.acornfiresecurity.com 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.

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”...

FS20X Fire and Flame Detectors www.acornfiresecurity.com 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.

www.acornfiresecurity.com 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.
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.

“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).
www.acornfiresecurity.com FS20X Fire and Flame Detectors Operation Configuring the Detector N OT I C E To activate changes to the settings using SW1, SW2, or SW3, reset the detector by cycling the 24 VDC power.
