Logged the base unit on the Internet and the other units just added on. I bought the package with 7 smoke detectors and purchased an additional smoke CO afterwards. I would like to have been able to purchase a package with a few smoke and a few smoke CO detectors. But it worked out ok.

I love these SD19-W Wireless Interconnected Smoke Alarm because they were very easy to program to interconnect!!! The instructions were easy to understand and the customer service was great.

Tim Kelsey

SC07-MR

Piece of mind was the main reason, long battery life and a glacé at the phone to know all is well. Setup is an easy, just label each one and setup in app before hanging up. Recently wife called 911 because are old unit said carbon monoxide when it was just a low battery. Will not happen with this setup.

Very pleased with the purchase! The alarm is loud, the setup was fast, and it looks nice on the wall.

XP0A-MR

Easy to set up and works well. Be careful to order the correct versions.

Victor Belba

SC07-MR

Excellent customer service and superb products. I am totally impressed with the SC07-MR. Set up is exceptionally easy! They look to be solidly built and though unobtrusive, are attractive to look at. I like the fact that the LED and LCD displays are not constantly on. Not only saves battery power and extends battery life, but not an annoying bright light to look at in the middle of the night.

No need for wiring, and installation process was effortless. Works perfectly.

Item received and installed in my garage, I had my garage heater on the other day working in my cold garage and all of a sudden I am hearing this alarm. Only to find out my X-Sense going off due to the heat sensor. I was like. This think really works. Good addition to my safety.

So many fires start in the garage. We all have so many batteries stored there for bikes, power tools, etc. I put two in my 3 car garage, if some thorns, it will give us time to get out, maybe time to save the house.

I have at least 20 of these in my two homes. I had one go off and send a text that I had a leak at my boiler. I plan on putting a devise on my water line where I can shut off water after getting an alert.
