First Alert SA511CN2-3ST Interconnected Wireless Smoke Alarm with Voice Location, Battery Operated, Pack of Two We paid $70 per pair from Amazon on Jan 4, 2018. We bought 3 sets for a total of 6 detectors. They arrived on Jan 7 and I just finished installing them tonight. So far, I am very impressed with these smoke detectors. I wanted to provide a review to share
my experience with you. Let me start with a list of PROs and Cons. CONs: Here are some tips to help you program and link them. What I did is put batteries in all 6 detectors and assigned a different name to each one. To do this, Now you are
done programming that unit and the assignment will remain even if you replace the batteries. Linking them is easier, especially if you have them all in front of you on a table, bed, couch, or floor. Unit 2 is now linked. Repeat these steps for the unit 3, unit 4, and so on. It does not matter in what order you link them
because they use a mesh network to communicate. They should remain linked even if you replace the batteries. I would suggest that the bigger your house, the more you buy. The main reason for this you want to situate each detector in such a way that no two are separated by a distance of more than 50 feet apart. Also you need to consider the line of sight path from one unit to the next closest. Is it a clear shot? Does the signal have to pass through multiple walls? Are the walls drywall, brick, or concrete? Are the walls zig zagged at angles or a nice clear perpendicular path? Something else comes to mind. Make sure you are using good quality batteries, like Duracell, and check the expiry date on them. Also, if you put one in the Kitchen, consider mounting it on the wall away from the stove so you can reach the test button without having to stand on a stepping stool. That test button also acts as a way to mute the system in the event of a non-serious situation like burning a roast in the oven. You can squelch the system for 10 minutes to stop the panic of a full out serious alarm condition while you clear the smoke out. I plan on doing a follow up concerning my personal experience with this system as it pertains to: Update 1: The interesting part to this is that when I installed the unit in the pool house, I tested it. It worked. It
worked so well, Sure enough, I performed another test and it resulted in another negative. Pool house will not respond to the other 5, but |
