  A set of three dedicated triggers designed to detect long-lived neutral
particles decaying throughout the ATLAS detector to a pair of hadronic jets is
described. The efficiencies of the triggers for selecting displaced decays as a
function of the decay position are presented for simulated events. The effect
of pile-up interactions on the trigger efficiencies and the dependence of the
trigger rate on instantaneous luminosity during the 2012 data-taking period at
the LHC are discussed.
