The ATLAS detector at CERN's Large Hadron Collider (LHC) will be exposed to proton proton collisions from beams crossing at 40 MHz. At the design luminosity of 1034 cm(-2) s(-1) there are on average 23 collisions per bunch crossing. A three-level trigger system will select potentially interesting events in order to reduce the readout rate to about 200 Hz. The first trigger level is implemented in custom-built electronics and makes an initial fast selection based on detector data of coarse granularity. It has to reduce the rate by a factor of 104 to less than 100 kHz. The other two consecutive trigger levels are in software and run on PC farms. We present an overview of the first-level trigger system and report on the current installation st...
