Heat detector FDT221

firetemperature risefor fire safety applications

Product Description
Monitoring of rooms in which a quick temperature rise is expected in case of fire, or when optical detection is difficult. Equipped with two redundant heat sensors, so that in case of failure of one sensor, the detector still complies with the highest response class. Measures the ambient temperature and the temperature in the detector housing, so that a temperature increase can be detected immediately. Signal processing with detection algorithms (DA). The base must be ordered separately. Also available in different colors.
