Guidance on the specification, design, installation, operation and maintenance of automatic doors for safety, is provided by BS 7036, which comprises five standards. Automatic doors are operated by some form of presence-sensing device. Positioning of the sensors is critical for effective operation. Operator devices which move the door are typically electrical motor driven, pneumatic or hydraulic. Control units may be required. Where power supply fails doors operate manually. Control systems have lifetimes of between 10 and 20 years.
