<br />HD-600 SERIES TESTING METHODS <br /> <br />-Models HD-601/HD-621 and HD-602lHD-622 can be tested by the application of quick heat from any convenient <br />source. A portable hair dryer is recommended. However, do not apply heat that exceeds the fixed-temperature rating <br />of the detector.'. <br /> <br />_ Models HD-603/HD-623 and HD-604/HD-624 cannot be tested. However, the fusible alloy element is gene~al/y con- <br />sidered so reliable that testing is not necessary. <br /> <br />SPECIFICATIONS <br /> <br />S075n.tbl, S075doti.wm', 5075dot2.wmf, 5075dot3.wrnf. 5075dot4.wmf <br /> <br />HD-601 & HD-621 HD-602 & HD-622 HD-603& HD-623 H0-604 & HD-624 <br />No marking. 0 Gray ring. 0 Gray spot 8 Black dot on white. ~ <br />Model HD-601 (one circuit) Model HD-602 (one circuit) Model HD-603 (one circuit) Model HC-604 (one circuit) <br />Model HD-621 (dual circuit) Model HC-622 (dual circuit) Model HD-623 (dual circuit) Model HD-624 (dual circuit) <br />RatEH)f -rise and Rate-of -rise and Fixed-temperature only Fixed-temperature only <br />fixed-temperature fixed-temperature 135.F (57.C). 200.F (94.C). <br />135"F (57.C). 200.F (94.C). <br />Application: nonnal Application: nonnal Application: unusually violent Application: unusually violent <br />temperature fluctuations and temperature fluctuations and temperature fluctuations and temperature fluctuations and <br />ceiHng temperatures not ceiling temperatures ceiling temperatures not ceiting temperatures <br />exceeding 100.F (3S.C). exceeding 100.F (3S"C) but exceeding 100"F (3S"C). exceeding 100.F (3e"C) but <br /> not 150"F (66.C). not 150"F (66"C). <br />Maximum spacing allowance" Maximum spacing allowance" , Maximum spacing allowance" Maximum spacing allowance" <br />UL: 50 ft. x 50 ft.

Reliance <br />should not be placed solely on heat de- <br />tectors forUfe safety. When life safety is <br />involved, smoke detectors MUST also be <br />used. Detectors must cHOT be painted. <br /> <br />Batterybaclcup: Heatdetectors should <br />be electronically supervised with battery <br />backup at the panel. <br /> <br />Rate-ot-rise mechanism: The rate-of- <br />rise mechanism may be subject to re- <br />duced sensitivity over time. Annual test- <br />ing of the rate-of-riseoperation is recom- <br />mended. <br /> <br />ELECTRICAL RATINGS <br />. 6-125 Volts AC, 3.0 Amp. <br />. 6-28 Volts DC, 1.0 Amp. <br />" 125 Volts DC, 0.3 Amp. <br />. 250 Volts DC, 0.1 Amp. <br />
