Simple to install and set up. I had bought a number of alarms to create a linked system using both wired and wireless links. I found I needed one more wireless alarm and was able to simply convert one by adding this module. My only criticism is that this cost quite a bit more than buying the original wireless units although they were supplied as a wired unit plus the same wireless unit which I had to install.
