•LOW ENERGY POWER OPERATED DOOR: A door with a power mechanism that
opens the door upon receipt of a knowing act activating signal, does not generate

mechanism or by other means
(such as the use of a hydraulic door closer or spring
mechanism).
•POWER ASSIST DOOR: A door with a power mechanism that activates by pushing
or pulling the door, reducing the opening resistance of a self closing door to allow

the door shall come to a stop and either immediately begin to close, or begin to
close after a predetermined time.
•PUSH-PULL ACTIVATION: A door where the user pushes or pulls a door equipped
