The door opener is small and slim in appearance, but entirely suitable for heavy duty applications. The opener can be programmed to suit specific requirements during installation. Safety features include obstruction detection which automatically reverses the door operation in the event of an obstruction being detected. Safety can be further improved with the use of the presence detection system, available as an accessory, stand by batteries are also available on request.
