Hey @mrthomas33. For professional monitoring, we only allow one Alarm Base Station per location and specific address to be professionally monitored. Therefore, if you would like to have professional monitoring for both a home and barn Alarm Base Station, they will need to have separate addresses that are valid and verified.
My best recommendation for you, since you would like the systems to be separate, is to have your home Base Station be professionally monitored, and your barn location to be self monitored. This will allow you to have two separate systems that can be triggered and not affect the other. If anything were to happen at your barn location, you could then call up the local authorities yourself in order to get assistance. This helps keep your home safe and secure while still having a system watch over your barn. If you would still like to purchase a plan for what would be the barn location, you can, in order to still get the benefit of cellular backup.
Another recommendation is to have all devices in your barn and in your home on one Base Station, one location, and one plan… This will require you to use range extenders to try to get z-wave coverage on the barn. The range extenders have a 250ft open air coverage, however that is with optimal conditions and doesn’t include things like forces of nature and building structures that are in the way. Our devices are also not rated for outdoor usage, so having an extender outdoors to bridge the gap may pose a concern during the first time setup.
I hope this helps clear it up for you and you’re able to find a way that works best for you!
