    Intelligent addressable optical and thermal multi sensor detector for loop circuit with 2 optical and 2 thermal sensors and potential bidirectional isolator for earliest fire detection and indication in all environments with difficult ambient conditions according to DIN EN 54-5/7 and CEA4021


    –          Highest reliability by intelligent combination of thermal and optical sensor signals with via algorithms

    –          Exact pollution recognition by an additional independent  measuring chamber

    –          Integrated temperature measurement as rate of rise procedure and maximum value in accordance to EN54-5 1A

    –          Detector sensitivities automatically calibrated and freely programmable

    –          Fault monitoring of the measurement chamber signal and  loop electronics

    –          Periodic sensor test

    –          Automatic and manual addressing on the loop

    –          Possibility for integrated Isolator and T-branch option

    –          Alarm output for the triggering of a LED indicators

    –          Functions completely integrated via loop protocol

    –          Disable and enable modes with individually adjustable sensitivities

    –          Storage of last maintenance date

    –          Self learning modes for the ambient conditions

    –          Display of the temperature environments of the fire detection system by a second temperature measurement

    –          Multicolour-LED for alarm- (red) and fault (yellow)

    –          Delivery including protective cover for installation phase

    –          Mode for adapting to environmental conditions

    –          Integrated isolator and t-branch (spur) facility

    –          Multicolor LED for alarm (red) and fault (yellow)
