Thanks for making and posting this!! It has been very helpful when a client asked me to install and commission an automatic door on board a cruise ship in china !
Sorry for the long delay. I am two years retired from dorma. The ED900, ED50, ED100/250 are all the same with exception to the drive motor size and spring size. The 250 allows more strength and flexibility with the port for the upgrade sticks. The best contact is dormakaba for greater details. Use the 800 # for help. The technical staff are excellent.
