Fire Detection, Heat-Actuated

Heat sensitive devices may be either "spot" or "line" type and operate at a fixed temperature or on a rapid increase in

temperature (rate-of-rise). Some detectors combine the fixed and rate sensitive principles.

The spacing guides listed are indicative of each detector"s relative sensitivity and, in each case, the spacing guide is the

maximum recommended separation between detectors for smooth-ceiling installations. For a given temperature rating, a

fixed-temperature detector which has a 30 ft (9 m) listing and one which has a 15 ft (5 m) listing will both respond at

approximately the same time to a geometrically growing fire if each is installed at its listed spacing. FM Approved rate-of-rise

detectors all have 30 ft (9 m) listed spacings, the maximum separation recommended by FM Approvals.

Installation of heat detectors at less than maximum spacing is necessary: to achieve earlier response; to compensate for ceiling

obstructions such as beams and joists; and to compensate for ceiling heights greater than 15 ft (5 m). Proper location and use of

heat detectors involves consideration of ceiling construction, the location of partitions, the maximum normal room temperature,

heat produced by the occupancy, and whether detector function is to warn occupants or to automatically actuate protection

equipment. Refer to Standard 72-1993 of the National Fire Protection Association and design specifications published by

jurisdictional authorities, as appropriate.
