Verify and document the following prior to functional testing:

1. The occupancy sensor has been located to minimize false signals, and the elevator cab does not have any obstructions that could adversely affect the sensor’s performance.
2. For PIR sensors, the sensor pattern does not enter into the elevator lobby.
3. For ultrasonic sensors, the sensor does not emit audible sound.

Note that some elevators are able to use weight sensors to provide occupancy sensing. In this case, document that the elevator uses weight sensing to provide occupant sensing and proceed to the functional test.

For each elevator cab being tested, confirm the following:

1. Verify that the lighting and ventilation controlled inside the elevator cab turn off after 15 minutes from the start of an unoccupied condition.
2. Verify that the signal sensitivity is adequate to achieve desired control. The sensor should not detect motion in the elevator lobby.
3. Verify that lighting and ventilation immediately turn "on" when an unoccupied condition becomes occupied.
4. Verify that the lighting and ventilation will not shut off when occupied. Stand in the elevator with the door closed and wait 15 minutes to confirm that the lighting and ventilation remain on.
