A DETECTION UNIT FOR DETECTING THE OCCURRENCE OF AN EVENT A DETECTION SYSTEM AND A METHOD FOR CONTROLLING SUCH A DETECTION UNIT OR DETECTION SYSTEM

摘要

The present invention relates to a detection unit comprising detection means for detecting the occurrence of an event. The detection unit further comprises processing means for controlling the operation of the detection unit and communication means for transmitting and receiving activation signals for interacting with further detection units. The processing means are designed for placing the detection unit into active mode upon receipt of an incoming activation signal, and furthermore for transmitting, in the active mode, an outgoing activation signal to at least one of said further detection units upon detection of an event and placing the detection unit into passive mode. The invention further relates to a detection system comprising a multitude of detection units as described and to a method for controlling a detection unit.
