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. Standard EN 54-5 , EN 54-17 Protection category IP43; IP44 with base attachment; IP54 with base attachment wet Operating voltage DC 12…33 V Operating temperature -10…50 °C; -10…70 °C Storage temperature -30...+75 °C Quiescent current 130...200 μA Ext. alarm indicator 2 without sounder base System compatibility FDnet -> FS20, AlgoRex, SIGMASYS Communication protocol FDnet Relative humidity ≤95 % Dimensions (Ø x H) 100 x 46 mm Color Pure white, ~RAL 9010
