Replacing a Radionics D4112, Need advice for New System

[humint]

Need advice as the system board has appeared to have failed.

I would like to know recommendations of a modern up-to-date system that I can install myself using the same sensors that are already installed in the house.

Please advise.

Any of the major brands will work just fine. My best advice is to read through a good sample of the posts here. The questions that people ask will give you a pretty good idea of the pros and cons of every system.

I would recommend an Ademco Vista model 20 depending on the number of zones / devices that are installed and the number of keypads you are installing. Ademco has a wide variety of peripheral devices and extremely reliable. I have systems that I installed over 20 years ago that I haven't had to service.
