Easiest to install

First Alert has really figured out how to easily replace an old alarm. The new mounting plate is universal, in that it can utilize the mounting screws already in place from your old alarm, no matter what brand.

Good product

I bought two of these for my home to replace some very old, traditional battery operated smoke detectors. I wanted the dual sensor to protect against multiple fire types smoldering vs. flash. The sensors were delivered in a timely manner. They were extremely easy to install and test. Takes about 5 minutes. I like the idea of a self-contained battery that I do not have to worry about replacing periodically, particularly since mine are not hard-wired into the electrical system. The sensors feel sturdy and appear to be well-made. I did quite a bit of research and read many reviews, and these were highly rated. I recently had a cooking issue that resulted in a lot of smoke no flame. The alarm sounded and when the smoke had cleared the room, it stopped within a reasonable time. I also have not had any false alarms, as have been reported with other brands with dual sensors. We will see if I get the full 10 yrs out of the battery, but so far I am very satisfied and would recommend this product.

very good product thank you

I ordered a three-pack of these, and they were very easy to install. I like the idea of not having to worry about changing the battery every six months and that these are dual sensor alarms capable of sensing both smoldering and quick burning fires.

Tenant Fire Protection

Reviewed: 07/27/2016 by Ann Lucas

I have owned several rental properties the last 20 years, and I have not found one tenant who will replace the batteries when they start chirping. I even provide the batteries, and they just are too busy or lazy to do the responsible thing. I was so pleased to find the smoke/fire alarms that do not require the batteries to be changed. It makes me feel so much better as a landlord. I hope the alarms are good for 10 years as advertised, but even five or six years would make me happy at this point.

Has all the features I want. Dual fire sensing capability and ten-year life. I have separate CO2 detectors but wanted a single device to cover fire threats. This is it.

Best smoke alarm out there. Best in class detection with dual sensors and no maintenance with the 10-year Lithium battery. Easy to install and highly recommended!

Alarms arrived on time and are easy to setup. Bought them due to the dual sensor protection and the 10-Year sealed battery. Probably, these features make this smoke alarm the best from what's available.
