First Alert SA511CN2-3ST Interconnected Wireless Smoke Alarm with Voice Location vs Kidde PI2010

The photoelectric sensor inside is quick to detect slow, smoldering fires. With a single silenced test button on the Fernley alarm, you can easily per...

They are expensive and are not durable. Factor that in into a decision to go with this expensive brand. In July of 2015, I bought these along with others (same brand and type) from a big box store, to replace all of the alarms in my house. Due to work being done in my house, I did not install them until Feb

Another worry.. if they continue to give false alarms we may eventually be desensitized to react fast IF THERE REALLY IS A FIRE. If it wasn't beyond the return window I would definitely send these back for replacements

I like the dual smoke detection a lot. What I don't like is the battery placement. A previous Kidde single detection SA unit had an external door that when pressed would pop-open, and the 9v battery would easily slide out/in. This was great for vaulted ceiling requiring a tall ladder to reach; now battery access in this unit is risky with vaulted/difficult ceilings

Overall, a good product and highly recommended in an older home where alarms aren't already interconnected by hardwire.

I'm assuming these all work, and according to Consumer Reports these are well rated, so my review is focused on the installation. First issue, the battery cover is on the back / mounting side of the unit. That means you can't just open a cover like my old units had. Second, getting the unit to attach to the mount is a real pain

they communicate to each other, like the voice telling which alarm is going off. no false alarms.

Units have been installed over a month now and seem to be working with no false alarms.

This is nice when you have 8 of these going off in your two story house. I have not placed any alarms in my kitchen, however one of these is in the adjacent room. Over the course of a year, I have had probably 2 times that the alarms have gone off from bad cooking. For the most part false alarms have not been an issue

Maybe someone else can reply. The instructions for the Kill-a-watt meter say that Watts are for Active Power, whereas the VA reading "is the apparent Power. (VA=Vrms Arms)". I will note that smoke detectors are in an interesting category of device for which 100% of the objective reviews are NOT based on the object's primary purpose

Like the smoke detector fine worked well bought it December 2019 failed August 2021 called the company free replacement free shipment pretty good stand behind their equipment I would buy again.

It makes for easy insulation. BEWARE of their 10 warranty. They will make good on the warranty, but you must pay the postage to get it to them and must prepay the postage to get it back. With that kind of warranty from Kidde, you can almost buy a new one instead of paying all that postage
