Every building entrance shall be secured by a door equipped with a deadlocking latch with at least a one- half-inch latch bolt projection. The latch shall be operated from the outside by a key and from the inside by a device which does not require a key or any special knowledge to operate, such as a turnpiece, handle, knob, panic hardware or electric latch release system which can be overridden by doorknob release. If an entrance is so constructed that entry to the interior of the building is gained by passage through an enclosed vestibule, the requirements of this section shall be deemed to be met if either the outer door leading from the exterior to the vestibule or the inner door leading from the vestibule to the interior of the building is equipped with the type of latch prescribed herein. A double leaf door shall be deemed to meet the requirements of this section if the inactive leaf is equipped with flush bolts at head and foot and the active leaf is equipped with the type of latch prescribed herein. The requirements of this section shall not apply to a building entrance where an attendant is continuously on duty.
