What I appreciate and admire about First Alert is I was able to buy the same model I had and it fit perfectly on the base. I am so thankful to be able to swap out my old smoke alarm for my new smoke alarm in seconds!

Just what I ordered!
Products were properly pulled from the shelf and sent. Arrived in good shape and the 2 units replacements for existing were installed the next day and found to be working.
I highly recommend this retailer.

THE place to buy First Alert products
First Alert products are excellent, including this simple battery powered smoke detector. I used this one to ensure I had both PE and Ion detection in a bedroom.
The First Alert Store has great prices, very quick shipping and superlative customer service.

Easy to Install
We recently purchased a house that came with a SA303 from 2009. Happy to say that the newer model SA303CN3 fits into the existing bracket. Put in a battery, close the lid, and twist in -- as easy as pie.

Back to Basics
I have found these basic battery run smoke detectors are my favorite. I have scheduled calendar reminders for regular tests and battery replacement so I never forget and my detectors are always on guard..

First Alert Smoke Alarms
I have always bought First Alert Smoke Alarms and I like them.
Thank God I have never actually had a fire to really test them.

THAT Was Easy!
I was especially impressed with the assistance I received over the telephone. I had old alarms. Maria checked the serial number, told me that, yes, the alarms had outlasted their usefulness and then checked to recommend replacement that would allow me to insert the new alarms in the old frames. And, by the way, they were on sale. I ordered them online. They arrived promptly. Sure enough, they fit into the frames that were already installed in the ceilings. It couldn't have been easier.
