Norton 7700 Power Track
The Power Track® Series combines the function of a single-point electromechanical door holder with the proven reliability of a standard 7700 Series door closer. The track assembly contains an arm slide and solenoid operated hold open mechanism and is available with or without an integral smoke detector. Shipped with a track only, the closer is mounted on the door; the track and hook-up box are mounted to the frame face or frame soffit depending on the installation requirements. The degree of door hold open is selected by adjustment of the telescoping arm. Any power interruption will release the arm slide and the door will close. The door can be manually released at any time.
