Ease of Installation and Price

The 3 smoke alarms were much improved over the last ones I bought years ago with respect to being able to insert the alarm into the bracket with ease. Also all the alarms go off in any one of them detects smoke/fire. Would recommend them to anyone seriously interested in their own safety!

happy in safety

I changed all of our 14 year old smoke alarms. It took less than 1 hour. We hadn't known the alarms are only good for a defined time.

Thank goodness your local

Our smoke detectors decided to kick the bucket New Years weekend after 15 long years! We were so glad you were local - we were able to pick up the replacement devices and saved a TON of money versus buying replacement devices from local big box stores. Your staff was so friendly and so accommodating! I hope all of my neighbors buy their replacement devices direct from you when the time comes!

Replaced a 8 year old unit, fit and worked as expected. Glad they still make this model. Would have been a pain to install another style.

Low price, high quality and easy to install

The price for the three sets of 120VAC hardwire alarm I ordered from First Alert beats anywhere else. The shipping was fast and the installation was easy and straightforwards as the model is compatibile with the ones to be replaced in my house.

Dealing with the first alert store was great. Order came on time and people I dealt with were VERY HELPFUL. Smoke alarm was a replacement from an old one. Matter of changing electrical cable and plugging in. Easy

120VAC Hardwired Smoke Alarm with Battery Backup

I have 12 of this smoke alarm in my home, all of which have been perfect for the past 12 years. Had to replace only one unit as a plastic clip that holds the battery in place broke. Highly recommended.

Play it safe

I have six of these devices in use and they have just passed their warranty expiration date 10 years. It doesn't hurt to have a spare on hand.

My existing alarms are now going on 10 years old & all probably need to be replaced. I was extremely pleased to find my model on-line for a reasonable cost. Received it within a couple of days & easily installed it.
