From the manufacturer


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.

Working smoke alarms cut the risk of dying in a home fire by 50%, and that's important because a home fire starts every 83 seconds! The faster you know about a fire, the faster you can start moving your family outside. The First Alert smoke alarm with silence button allows you to both silence a non-threatening alarm and to test the unit's functionality. It features a low battery alert to remind you when to change the battery and has a missing battery guard to ensure that a battery is placed inside the alarm. The side battery drawer slides open for easy battery replacement. A blinking power indicator on the unit confirms that it is receiving power. The alarm contains an optional pin to lock the battery and unit in place for tamper resistance. It can be mounted on either the ceiling or the wall and can be used in mobile homes and RVs. It includes one 9-volt battery and has a 10-year limited warranty. UL listed for safety.Bree Norlander: what's in the Box: One smoke alarm, user's manual, and one 9-volt battery

These work well and are not too expensive. They are easy to install. Some smoke detectors have a 10 year battery but never seen to last that long. I don't mind replacing the battery because it's easy to replace.

I purchased 2 for $15 and one stopped working after 3 years. I changed the battery, but light still red. Called mfg and was told the unit is defective, I have another as a backup, so it doesn’t matter to me. Woke me up at 3am, but I guess that’s a good thing.

Cheap alarm for peace of mind, easy to replace if there's a problem

Reviewed in the United States on October 17, 2022

Style: SA303CN3Pattern Name: AlarmVerified Purchase

Bought this alarm to replace our "we changed the batteries last month, why is it intermittently beeping" alarm. This one is so sensitive that it goes off when the oven's on BROIL.

The good news is that it's really easy to turn off for a false alarm; just press the button on the alarm's face.

It's easy to install and comes with instructions and hardware. If you are purchasing a replacement, you don't even need to install hardware. You can easily twist this on to an existing plate (again, if it's a replacement - worked for us, your mileage may vary). We purchased new smoke alarms <5 years ago, have replaced the batteries several times, and are now replacing the alarms themselves.

PRODUCT CLAIMS
- ionization sensor for smoke detection - I'm not sure about this, but we have one outside of the bathroom, and it does go off during particularly steamy showers
- battery operated alarm unit monitors during power failure - We've had no issues (and, if anything, more peace of mind) during times without power
- easy to install - VERY easy. You need a drill or screwdriver. That's it.
- single test/silence button - Easy to find, easy to turn off, easy to test. Battery is easy to check and change with the side battery door.

If you need a smoke alarm at a good value, and don't mind replacing it a few years down the line, this is the product for you. For this price, it's easy to get one for each bedroom and floor of your home (as they recommend). Keep a few extra 9V batteries handy in case you need to replace one at an inconvenient time.

Feels solid, battery pull out was easier to access than my old alarm, test worked great. everything you need for an easy mount

Reviewed in the United States on April 20, 2018

Style: SA320FFPattern Name: AlarmVerified Purchase

Kind of hard to review something that hasnt saved your life yet...

It feels like its made of quality materials especially compared to the 16 year old smoke alarm it will be replacing/working along side.

I like the drawer pull out for battery replacement. But as I have arthritis in my hands I found it a little bit hard to get the drawer out and the batteries out. Went in easy enough. That being said it was a LOT easier putting in the two AA batteries than finagling the old alarm and its 9v battery compartment.

Comes with everything you need to mount except the screw driver and drill if you like to pre-drill.

I would purchase again. Test seemed to work. But only time will tell, as with any sensor/alarm when there is something for it to sense and go off about. I believe it was rated well in consumer reports but do not quote me. Always check for yourself as this varies by year.

I got this one because my old one is a smoke alarm only and I wanted to have a dual sensor smoke detector fire alarm. no, sensing smoke is not the same thing as sensing a sudden flame up. Smoke is smoldering and a sudden flame up doesnt necessarily have smoke to set the alarm off. Plus learning my old alarm is 16 years old made me feel a little iffy. Apparently some smoke alarms are guaranteed for 25 years. Not sure about the new one. Newer ones seem to be good for 10 years rather than 25. But I feel safer knowing both the old and the new are on board.

Maybe more than you wanted to know but I thought if you are like me and you did not know that there are two types of alarms regarding possible fire you might appreciate the TMI.

Cheers!
