ResumoThis paper describes the trigger system of the OPAL detector at the e+e− collider LEP and its performance during the first year of data taking. A high level of redundancy and fine detector segmentation at the trigger level led to a high efficiency for all considered physics reactions while the trigger rates were kept low.
