Power Track series door closers combine single-point electromechanical door holder with standard 7700 Series door closer. Assembly contains an arm slide and solenoid-operated hold-open mechanism and is available with or without an integral smoke detector. Closer is mounted on the door, and track and hook-up box are mounted to either the frame face or frame soffit. Any power interruption will release the arm slide and the door will close. Door can be manually released at any time.
