    So a spring wound timer would not be acceptable, unless it had an always on detent position.

    Without the always on, it would get a red tag from me.

    Personally, I wouldn't do it, as well as in a mech. room.

    I personally don't show sensors on drawings in mechanical and electrical rooms, in energy code I use exemption "sensor is not required where it can endanger safety of occupant"

    Auto with key switch override.
    I would rather see more outlets for plugging in test equipment and aux lighting, change to led fixtures.
