How do I check the revision on my VISTA 20P panel?

There is a small chip on the board that is about 1 inch by 1 inch where your panel's revision can be found. The newest revision is 9.12, and those chips look like the ones in the picture below.

As you can see, the 9.12 revision PROM chip's number is printed after the letters and numbers "WA20P". On your panel, you will see something similar, and can very quickly ascertain the pane's revision simply by reading the numbers off that chip. 9.12 is the revision you will need if you are looking to use Total Connect with your VISTA 20P security system.

For those who do not have a 9.12 revision panel, the solution is simple: the old chip can be replaced with a new one without a loss of programming. You simply power the system down, pop the existing chip out, and put the new 9.12 revision chip in its place. The entire process takes about a minute to perform and is simple once the other chip is lifted. Once you've done that, feel free to sign up for any of our alarm monitoring packages that work contain Total Connect: self-monitoring or monitoring plus.
