A double-level trigger system has been developed for the KLOE experiment. C ustom electronics asserts a trigger in a 2 mus decision time. The decision is based on the combined information of the electromagnetic calorimeter and the drift chamber. The entire trigger system is continuously monitored, an d data flowing from the trigger system hal e allowed both an efficient onli ne monitoring of the detector and an online luminosity measurement.
