INTRODUCTION1.1 ScopeThis standard sets performance requirements for radiant energy-sensing fire detectors used for automatic firealarm signaling for the protection of occupants, building space, structure, area, or object.1
11、.2 Basis for RequirementsThe requirements of this standard are based on experience, research and testing, and/or the standards of othernational and international organizations. The advice of manufacturers, users, trade associations, jurisdictions, andloss control specialists has also been considered
12、.1.3 System of UnitsUnits of measurement used in this standard are United States (U.S.) customary units. These are followed by theirarithmetic equivalents in International System (SI) units, enclosed in parentheses. The first value stated shall beregarded as the requirement. The converted equivalent
13、 value may be approximate. The Appendix lists theselected units and conversions to SI units for measures appearing in this standard. Conversion of U.S. customaryunits is in accordance with the American National Standards Institute (ANSI)/Institute of Electrical and Elec-tronics Engineers (IEEE)/Amer

GENERAL INFORMATION2.1 Product Information2.1.1 Radiant energy sensing detectors fall into two (2) general categories: flame detectors and spark/emberdetectors, depending upon the
17、 source of radiant energy they are intended to detect and the ambient inwhich they are to be used. Flame detectors are intended to respond to the radiant emissions from a flameand are expected to operate in normally illuminated environments. Spark/ember detectors are intended torespond to embers in
18、a fuel stream flowing past them within a sheet metal pneumatic conveyance duct,chute, conveyor, or other location of limited illumination.2.1.2 All radiant energy sensing detectors have a limited field of view and rely on a line-of-sight transmissionof radiant energy from the source to the detector.
19、 Radiant energy sensing detectors employ infrared,visible, and/or ultraviolet sensors or combinations of sensors, selected to match the radiant emissionsexpected from the source to be detected. Since each fuel emits unique spectra, not all detectors are capableof detecting all fuels.2.2 Requirements
20、 for Samples for ExaminationFor functional tests outlined below, the manufacturer shall provide at least four detectors which are deemed tobe representative of the manufacturers normal production with regard to construction and calibration. All fourdetectors shall be subjected to the baseline, flame
21、 response sensitivity, and false alarm tests; the remainder of thetests shall be spread over the four samples as outlined in Table 1.Table 1: Test AssignmentsTest Paragraph Sample 1 Sample 2 Sample 3 Sample 4Baseline Sensitivity 4.1.2 x x x xFlame Response 4.2.2 x x x xFalse stimuli 4.3.2 x x x xFie
22、ld of view 4.4.2 xSwitching 4.5.2 xHumidity cycling however, alarm initiation shall be no greater than 30 seconds from theinitial flame exposure.3.2.9 Detectors rated at or above 30 V ac and 60 V dc require a proper ground terminal to be provided.3.2.10 Duplicate terminals or leads, or their equival
