Smoke

Extinguishers

Escape Ladders

Smoke Alarms

Place at least 10 feet from kitchen/stove, and on the ceiling or high on a wall, no more than 10 inches from top.

Carbon Monoxide Alarms

Carbon monoxide alarms can be placed anywhere, not just the ceiling or high on a wall. They should be replaced every 5 to 7 years.

Fire Extinguishers

Keep in the kitchen and garage, but make sure to have the right grade for the type of fire that might occur.

Escape Ladders

Have at least one if your home has more than one story. Each room needs 2 escape routes; in most bedrooms it's the window, so have a ladder nearby.

Fast delivery, easy install
Was replacing another brand, while the base was slightly different, the manufacturers have accommodated a hole pattern on base so you can easily adapt (at least in my case).My only concern is the date code of manufacture date is March 2023. It's Feb 2024 at install. I guess this will last 10 years, we'll see?

Purchased two of these Smoke Alarm with 10-Year Sealed Tamper-Proof Battery for my sister. When I pulled two alarms out from her newly purchased condo, they only had two wires and they didn’t seem to be doing nothing. Instead of dealing with wiring, I decided to get her these. They were very easy to install and they have a very loud sound to them. The price was good and the product is excellent. Just what was needed.

This installs easily. I wrote the expiration date on the outside of the unit, because I don't want to take it off the wall to see when it needs to be changed. The whole unit expires 10 years after activation, these arrived shortly after manufacture, so I won't worry that they were already old when I got them.
Just install the unit and don't worry about changing the batteries! I will still check mine twice a year by pressing the "test" button.

5.0 out of 5 stars Simple and cost effective
Reviewed in the United States on January 30, 2024

Hopefully it lives up to the long battery life listed but will be great not having to worry about the batteries running out so frequently.

Installation was a breeze as you don't need to even plug them in, being fully battery operated. You can just put them anywhere with a few simple screws (included with drywall anchors).

The ones I installed chirped just fine when holding the test button. There is a small red LED that flashes every several seconds though. I suppose this is to let you know it's doing its thing. It's actually a little brighter than expected.

Hopefully It never gets used but great having a well known company behind the units. They are shipped in plain builders boxes for those that reviewed them being fakes. The units themselves are exactly what was expected and pictured, from First Alert. Maybe it would be helpful on the page to have this better pointed out to not catch people off guard.

Overall great product for great price. Some of those fancy ones are nice but just so expensive, and then issues with the app's over the years are no fun. Some things are just better simple.
