I have a CompuStar 2W900FMR and want to add a backup battery. I've searched around to see which ones would work for my alarm but have not found an answer. I was looking at the DEI 520T. Will this unit work on my alarm? If anyone can help that would be great!

It may work.
If you have the 2W900FM-A (alarm only) it will work.
If you have the 2W900FM-AS (alarm and remote start) it will NOT work.
If you have the Pro 2W900FM-AS (alarm and remote start) it will also work because that brain is different and has an input for a backup battery.
