Fike Hochiki HF-24 Ultraviolet Flame Detector

HF 24 ULTRAVIOLET FLAME DETECTOR HF 24 is suited for use wherever there is a need for detection of fires which can develop quickly where contents have great value applications include Petroleum Storage Photographic or Film Storage Computer Rooms Print Shops Museums HF 24 is not a substitute for smoke or heat detectors is an added level of protection against fast flaming only is no set area for which the HF 24 Ultraviolet is able to cover The reason is that the size of fire and the distance from this fire to the detector all how the detector will respond There is one non however and that is very small fires must have duration of at least 7 15 seconds if within 12 feet 20 seconds at 25 feet HF 24 uses an ultraviolet detector tube which absorbs weak ultraviolet light such as that emitted from a This is detected as a train of discharge pulses a current The electronic circuitry in the detector translates this action as an alarm signal There is counter circuit which prevents the alarm from occurring one shot ultraviolet light such as lightning or cosmic Additionally there are circuit refinements which the detection of only wave lengths from 1850 to 3000 thus ignoring visible and infrared light Reverse Side for Range Graph Wiring Diagram on back latest revision at www hochiki com power consumption FEATURES Detects fast flaming fires Highly reliable long life UV receptor tube HF 24 can be intermixed with other types of on the panel s detection circuitry with Hochiki America s standard and heat detector bases Size and color similar to other Hochiki America and heat detectors Easily Maintained cleaning can be accomplished disassembling the detector Not UL Listed SPECIFICATIONS Voltage Voltage Current Current to Ultraviolet 17.6 27.7 VDC 15 30 VDC 200 24 VDC Maximum 3000 Angstrom Temperature 14 to 122 Fahrenheit 10 C to 50 C HSC 4R HSB series NS4 series NS6 series HSC xxx L series bases subject to change without notice Ivory ACS America Corporation Village Drive Suite 100 Buena Park CA 90621 2268 714 522 2246 Fax 714 522 2268 Support 800 845 6692 or technicalsupport hochiki com RANGE LISTED Wire 1 Flame from a candle or lighter 2 Flame from a wad or newspaper burning flame DIAGRAMS Series and HSC Series Base SERIES SERIES SERIES OF LINE LISTED MAX OF LINE 1 2W MAX LIMTED AT 24VDC America Corporation HF 24 subject to change without notice
