How do ADA Door Openers Work?
ADA door openers use push buttons or touchless activation switches to operate the door. Openers consist of a header, which houses the control, motor and gearbox, and also an arm assembly on the exterior. The diagram below shows the different components on a door application. In action the basic process looks like this: the activation switch is tripped which sends a signal to the door opener controller. This closes a contact on the door opener's control system which in turn tells the motor to power open. The motor will then push the door arm to open the door. The controller has a time delay built in that will immediately start its time delay once the button is pressed. Typically this delay lasts for about 15-20 seconds. Once the delay runs out, the controller will cut the power to the motor off and the door will begin to close under spring or hydraulic pressure depending on the door opener. If there are any additional sensors on the door for safety, they will be able to re-open the door if any safety sensor is activated. Once the door comes to the "closed" position the sensors will shut off until the door is once again activated by the handicap push button.
