Touchless solutions and complying with ANSI/BHMA A156.19
Touchless actuators that can be operated by the wave of a hand are considered a knowing act by A156.19, but the detection range (the distance from the waving hand to the switch) should be no more than 12 inches. In the 2019 edition of the standard, wireless transmitters were added to the definition of a knowing act. While there isn’t a specific allowable range for wireless transmitters, the user should be within view of the door before actuating the automatic operator, to help ensure that other building occupants are not in the path of the moving door.
