Hochiki DCD-CE3 Conventional Combined Heat Detector 90°C - Ivory Case

The Hochiki DCD-CE3 is a conventional heat detector in an ivory case that combines rate of rise detection with a 90 °C fixed temperature element. It uses a thermistor and linearising circuit to give an accurate linear response, and suits areas where medium ambient temperatures exist or where smoke detectors are unsuitable because of steam or cooking fumes, such as kitchens and drying rooms. It works on the majority of conventional fire alarm systems and fits the Hochiki CDX range of conventional bases; a third terminal provides a remote indicator output.
