The 280B-PL Series heat detectors offer fixed temperature or combinationrate-of-rise and fixed temperature features. The heat detectoris available with a white plastic reversible mounting plate. Theplastic plate can be used for either flush or surface mounting. It includesa white skirt which covers the space between detector baseand the mounting surface.
*NOTE: Maximum detector coverage has been determined by UL toprovide detection time equal to sprinkler devices spaced at 10 ft(3.05m) intervals on a smooth ceiling 15 feet 9 inches (4.8m) high.Higher ceilings may adversely affect detection time. Earlier detectionmay be obtained by reducing the spacing between detectors.(See NFPA 72, Chapter 5)
Detector twists and locks onto mounting plate. Mounting plate maybe surface mounted or mounted onto any 3 1/4" (83mm) or 4"(102mm) octagon box.
