Description

Where environmental conditions rule out the use of smoke detectors, MD601Ex/MD611Ex heat detectors may provide an acceptable, though less sensitive, alternative. For general use (particularly where the ambient temperature may be low) a ‘Rate-of-Rise’ (ROR) heat sensor is preferred. These detectors react to abnormally high rates of change of temperature and provide the fastest response over a wide range of ambient temperatures. A fixed temperature limit is incorporated in these detectors. In kitchens and boiler rooms etc, sudden, large changes in temperature are considered ‘normal’. Fixed temp. [static] detectors should be used in this case.
