Fireclass 631H-F Fixed Temperature 90 Heat Detector

Fireclass 631H-F Fixed Temperature 90 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 rateof- 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.

Features:

• Reduced installation costs due to easier termination, polarity independent wiring and use of common base for all detector types
• Lower cost of ownership as no radioactive source disposal costs together with less spares holding
• Easier system design with full range of detector types including intrinsically safe models
• Higher safety in accommodation areas by using the unique Carbon Monoxide (CO) detection
• IP55 rated 60oC and 90oC fixed temperature heat detector
