The electric dead bolt is exactly what it sounds like. This lock is the standard dead bolt that will lock with the use of an electronically activated motor when supplied with a signal or a code from a designated source. It is commonly used to secure outer doors or hidden doors and the dead bolt has to be installed into the door while the catch gets cut into the frame. On the electric dead bolt the actual lock on the door is activated to secure the entire combo to the notched plate on the frame. And now I hope this clears up some of the questions posed so often trying to decipher the nuances of these two similar locks that work in such different ways.
