  A model--independent search for deviations from the Standard Model prediction
is performed using the full $e^\pm p$ data sample collected by the H1
experiment at HERA. All event topologies involving isolated electrons, photons,
muons, neutrinos and jets with transverse momenta above 20 GeV are investigated
in a single analysis. Events are assigned to exclusive classes according to
their final state. A dedicated algorithm is used to search for deviations from
the Standard Model in the distributions of the scalar sum of transverse momenta
or the invariant mass of final state particles and to quantify their
significance. Variables related to angular distributions and energy sharing
between final state particles are also introduced to study the final state
topologies. No significant deviation from the Standard Model expectation is
observed in the phase space covered by this analysis.
