What Is An Automatic Door Opener?
An automatic door opener or sometimes known as an ADA Door opener or handicap door opener is a type of electrically powered door opening device. Automatic door openers differ from door closers because they use electrical power to drive a dc motor. Standard door closers are strictly hydraulic and mechanical. In this article we explain what an automatic door opener is.
An automatic door opener can be defined as an electro-mechanical device that is mounted on the top of the door frame (top jamb) with a connecting arm that is used to push or pull the door open. Most automatic door openers utilize a microprocessor control board that provides specific voltages to the dc motor in order to control the speed at which the door automatically opens.
Electric Opening, Mechanical Closing
Due to fire code requirements in the USA, a fire door must automatically close. Only a handful of automatic door openers are actually fire rated. The Commander is one of the automatic door openers that is fire rated. With a fire rated automatic door opener the door will open from the voltage supplied to the dc motor. However, when it closes, it uses the mechanical energy from an internal clock spring to gently close the door. This is due to the fact that in the event of power failure, the automatic door opener will still close if there happens to be a fire.
