Description:

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

Properties:

– 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)
