VERTICAL DETECT-A-FIRE DETECTOR SPECIFICATIONS <br /> Vertical D-A-F detectors are designed for use in both 'ordinary" or "hazardous" locations. For 'ordinary" use, they may be mounted to <br /> any approved junction box with 7/8" diameter opening by using 1/2-14 NPT mounting nuts. The device may be wired in or out of con- <br /> duit, depending on local preferences and codes.To facilitate supervision of system wiring,four lead wires are provided on normally open <br /> vertical detectors (that close on temperature rise). When mounted in a appropriately classified mounting box (i.e. Figure 7), detectors <br /> are Underwriters Laboratory and Underwriters Laboratory of Canada listed, and FM Approved for hazardous locations. <br /> VERTICAL MODELS <br /> Table 1: Model Numbers 27121, 28021, 27120*, 28020* <br /> OF ,F °C oC Spacing(in feet) Color <br /> Setting Tolerance Setting Tolerance UL ULC FM RTI Coding <br /> 140 +7/-8 60 +4/-5 50 50 20 V-Fast Black <br /> 160 +7/-8 71 +4/-5 25 25 20 V-Fast Black <br /> 190 +7/-8 88 +4/-5 50 50 25 V-Fast White <br /> 210 +7/-8 99 +4/-5 25 50 25 V-Fast White <br /> 225 +7/-8 107 +4/-5 25 50 25 V-Fast White <br /> 275 ±10 135 f6 25 50 25 V-Fast Blue ° «os ° loos <br /> 325 ±10 163 t6 50 50 25 V-Fast Red ` <br /> 360 ±10 182 f8 25 50 30 V-Fast Red i <br /> ..,b- .."r <br /> MIX ME% <br /> 450 f 15 232 f 10 25 50 30 V-Fast Green 3.°9°.. 7°5,.. <br /> 500** ±15 260 ±10 50 50 30 V-Fast Orange <br /> 600** ±20 316 ±12 N/A 50 30 V-Fast Orange SIC <br /> 725** ±20 385 ±12 N/A 50 30 V-Fast Orange 12427120-000 12-x27121-000 <br /> 12-x27120-022 12-x27121-020 <br /> Notes: Figure 4.
