80SD9K00121 – FDOT500 – low profile optical-heat detector

Descripción

Low profile optical-heat detector, complete with self-learning circuit and short-circuit isolator.
Double technology detectors (smoke-heat) base their operating principle on the light scattering principle caused by smoke particles present in the air (TYNDALL effect) and on temperature monitoring within 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. The smoke detector has the automatic gain control function; a microcontroller calculates reading compensation to keep sensitivity constant in time.
