What do I need to get to have my Merlin Legend system open an electronic door lock? I know there are devices that will open a doorlock on a signal via a T/R line, but I don't remember what they are called or where to buy one.
There is a company called Viking which sells this type of equipment. It is not as expensive as the last persons recommendation. It hooks into a CO port. It works fairly well. It is sold at Graybar and they have a website at vikingelectronics.com
that open or closes a dry contact when there is ringing current. It only cost about 20 bucks. The set up works real nice because I can program an auto-dial button on the phones that will open the door, and I don't have to train the users to push # to activate the lock. I also don't have to have a device that picks up the line, like the Viking requires.
