Fireclass 611H-F Conventional 60 Celsius Fixed Temperature Heat Detector

Heat detectors offer an acceptable, but less sensitive alternative to smoke detectors if environmental conditions rule out their use. The 601H-R (rate-of-rise), 601H-F, 611H-F and 631H-F (fixed temperature) detectors detect abnormally high rates of rise of temperature and abnormally high (static) temperatures respectively. For use particularly where the ambient temperature may be low, a rate-of-rise heat detector 601H-R is to be preferred.

A fixed temperature limit is also incorporated in these detectors. In many environments, e.g. galleys, canteens, pantries and laundries, sudden large changes in temperature are considered normal therefore rate-of -rise detectors are generally not suitable in these cases and a slower response fixed temperature 601H-F, 611H-F or 631H-F detector should be used.
