The Autronica BD-26/T is a IP56 Heat Detector without socket, designed to be used in damp areas. The BD-26/T Heat Detector gives an alarm when it reaches a fixed alarm limit of 56°C, when the temperature increases slowly. When a rapid increase of temperature occurs, the BD-26/T will give an alarm at a slightly lower temperature. The Autronica BD-26/T is often used in places where Smoke Detectors are not used due to false alarms.
