Abstract (en)
[origin: EP0834844A1] Security devices are widely used for guarding spaces or areas (for example outdoor areas), with detectors monitoring different planes. It is a requirement for a good operation of a security device that the risk of false alarms should be reduced to a minimum. Each plane is subdivided into several subplanes in that the detector for each plane is provided with several sensors which are positioned so as to enclose an angle with one another. The risk of false alarms is substantially reduced thereby. <IMAGE>
