Abstract (en)
[origin: EP1093100A1] A passive infra-red (IR) detector has an entrance window (3) for IR-radiation, an IR-sensor (5) with an evaluation circuit (6) and an anti-masking device, comprising an optical transmitter (8,10) and an optical receiver (9), for detection of processes or optical changes directly in front of the detector and/or changes of the optical properties of the entrance window (3). Two channels (14,15) are provided for evaluation of the anti- masking device signals, one channel (14) being designated PL- channel, and reacting to time-limited processes, and the other (15) is designated as RT-channel, for reacting to time-stabilised processes or changes. The signals of two channels (14,15) are evaluated in together.
