Rate-of-rise heat detector
Low profile rate-of-rise heat detector, complete with self-learning circuit and short-circuit isolator. Rate-of-rise heat detectors monitor the temperature increase within the area they are installed in. A microcontroller analyzes the signal received from a precision NTC type temperature sensor, activating the alarm if the temperature increase exceeds 5 °C per minute.
