Hochiki Conventional Heat Detector – DFJ-CE3 Fixed Temperature 90°C

The Hochiki DFJ-CE3 Conventional Heat Detector is a fixed-temperature sensing device designed to activate at 90°C, making it ideal for environments where smoke detection is impractical. This heat detector uses an advanced thermistor and linearising circuit to deliver an accurate, linear temperature response, ensuring early and reliable fire detection in high-temperature or steam-prone areas.

Commonly used in kitchens, boiler rooms, drying areas, and industrial spaces, the DFJ-CE3 is a robust solution for locations where steam, dust, or cooking fumes would cause nuisance alarms with conventional smoke detectors. It is approved by LPCB and VdS, ensuring it meets strict international fire safety standards.

The detector is compatible with a wide range of mounting bases and includes a third terminal to support a remote indicator, enhancing system flexibility and user notification.
