80SD5700121 – FDT500 – low profile heat detector

Descripción

Low profile heat detector, complete with self-learning circuit and short-circuit isolator. Heat detectors monitor the temperature values in the area where they are installed. A microcontroller analyses and compares the signal received from a NTC type temperature detector and activates the alarm if the read temperature exceeds 58°C.
