IR3 Flame DetectorTriple Spectrum Design Sensitivity Selection 20/20I User-Programmable Configuration Highly Immune to False Alarms Automatic and Manual Built-In-Test Explosion-Proof Standard 4-Wire Connection MTBF Minimum 100,000 Hours FM, CSA, Cenelec and ATEX Approved The Spectrex "SharpEye" 20/20I is a self-contained, triple-spectrum flame detector. The sensor band pass has been carefully selected to ensure the greatest degree of spectral matching to the radiant energy emissions of fire, and the lowest degree of matching to non-fire stimuli. The microprocessor design allows for unique field programmability not found in similar detectors. The 20/20I incorporates both Automatic and Manual BIT (Built In Test). The patented triple IR circuit design scans for oscillating IR radiation (1 to 10 Hz) in the spectral bands ranging from 4.0 to 5.0 microns. This highly advanced detector uses programmed algorithms which check the ratio and correlation of data received by the three sensors. Only detection of radiation emissions matching the spectral fingerprint of fire will produce an alarm, making the 20/20I highly immune to false alarms. The SharpEye 20/20I is extremely sensitive. It can detect a lxl sq. ft. gasoline pan fire at 200 ft. in less than 10 seconds. The sensitivity is user-programmable, offering 4 ranges of detection. The outputs 4-20 mA and RS-485 interface, as well as the standard alarm, accessory and fault relays, make the 20/20I the most diverse detector available. The 20/20I utilizes Mil-spec. electronic components and materials. The MTBF (Mean Time Between Failures) is calculated to be 100,000 hours (11+ years). This outstanding performance permits a 3year warranty on the entire detector, not just the sensors. The patented triple IR design offers two to three times the detection distance of any conventional IR or UV/IR detector. 218 Little Falls Road, Cedar Grove, NJ 07009 Telephone: 973-239-8398 Fax: 973-239-7614 E-mail: [email protected] Web Site: www.spectrex-inc.com The detector is explosion-proof and is designed per MIL-STD-810-C.
