The most common Title 24 acceptance test is the NRCA-LTI-02-A acceptance test.  It is the most basic test, comprised of testing the auto shutoff function of a lighting system.  To comply with the requirements in this test, all of the main area lighting (except emergency lighting) must automatically shut off when the room is usually empty.  For small rooms this means a vacancy sensor must be used, and for large areas either a digital time-clock or occupancy sensors can be used for compliance.
