Feature 1. Enhanced performance - The new DFJ incorporates the use of thermistor and linearising circuits to provide an accurate linear response heat detector 2. Modern low profile design 3. Twin LED indicator lamp 4. Low current consumption 5. Wide application - The DFJ has has the widest possible installation applicability as it is designed to sense heat in a vertical or horizontal position. Applications The DFJ Fixed Temperature Heat Detector is suited for installation where high heat output fires are expected or in areas where ambient condition would not allow the use of other detection methods (e.g. the presence of steam or cooking fumes such as in a boiler room or kitchen). Consideration should be given to the maximum normal operating temperature before deciding on the most appropriate DFJ detector for the application.
