      Direct replacement to one that was 27 years old and fitted when we bought the house. Came with a 9v Duracell battery installed. 2 screws to take the old ceiling mount off and replace with the new one. Old connection fit fine (new one is included if needed). Works just as good as the last one. 5 min job.
