HORIZONTAL DETECT-A-FIRE DETECTOR SPECIFICATIONS <br /> Horizontal D-A-F detectors are designed for locations where appearance is a factor. The low-profile, functional design <br /> lends physical protection of the detector while making it suitable for commercial, industrial, mercantile public buildings, <br /> institutions, and marine applications in non-hazardous locations (those classified as 'ordinary" under the National Electric <br /> Code). Flush mounted detectors are designed to fit standard 4-inch octagonal electric boxes and surface mounting detec- <br /> tors are designed to mount directly on ceilings or on 4-inch electrical junction boxes. Canadian Electrical Codes requires <br /> mounting only to an electrical junction box. <br /> Horizontal Models <br /> Table 3: Model Numbers: 27021-0, 27021-1, 27020-0*, 27020-1* <br /> Spacing 46, <br /> OF OF (in feet) RTI Color <br /> Setting Tolerance Coding <br /> UL ULC FM <br /> 140 +7/-8 50 50 20 Quick Black Flush Mounting Unit Surface Mounting Unit <br /> 160 +7 -8 25 25 20 for Concealed Wiring for Exposed Wiring <br /> / Quick Black <br /> 190 +7/-8 50 50 25 Fast White r — s — -- j ��• <br /> 210 +7/-8 25 50 25 Fast White <br /> 225 +7/8 25 50 25 Fast White - <br /> 275 +10 25 50 25 Fast Blue /L1° svr wis" s r <br /> 325 1 ±10 1 50 1 50 1 25 1 Fast Red __1 <br /> • *27020-0 and 27020-1 are normally closed devices and do not meetthe <br /> requirements of NFPA-72 for use as initiating devices(they are 2-wire devices). <br /> • *27020-0 and 27020-1 are not listed by FM with RTI. � A <br /> Table 4: Horizontal D-A-F Specifications 12-x27020-000 12-x27020-001 <br /> 12-x27021-000 12-x27021-001 <br /> Model Number Mounting Style Contact Operation Electrical Rating Figure 6.
