Happy Customer

I ordered 6 of these alarms to update the safety of my home. When they arrived in just a couple days, I was quite impressed! Aside from endangering my life on a stepladder, installation was a breeze. The hardest part was lugging the step ladder around. And figuring out some of the instructions about alignment, which could have been written a little better. But common sense prevailed. I got the job done. I'm a happy customer.

Has met all expectations

Bought this model to replace 10yr old models which lacked sealed battery. When recd, determined that all the ones I'd purchased tested okay. For me, this models universal mounts indeed worked fine with pre-existing screw holes from multiple vendors/models. Although my old models sometimes gave false positives for bath mist & kitchen fumes, these new models have so far been very well-behaved. Have not yet fired up the woodstove for winter... Hope the sealed battery indeed lasts 10 yrs!

Only 2 out of 3 worked properly

This was the only dual-sensing, 10-year smoke alarm I could find. I ordered three. Two are working properly. One malfunctioned right out of the box, with beeps and LED flashes signalling malfunction. I had to de-activate it and send it back. To their credit, the company responded promptly and graciously to my request for a new one, and the covered shipping to send the old one back.

This product is good if you want dual sensor in a 10 year battery only unit. Please note this unit cannot be connected to other alarms in a chain as there is not a hardwire option.

Again, ordered on 26July,2019, but just installed today 6 Oct.. Went very well. Was pleasantly surprised when I found out I could use the anchors from the old Kidde dual smoke alarms. I originally purchased the First Alert ones because I wanted a dual sensor smoke alarm with a 10 year battery which Kidde did not have. Thank you First Alert for selling one. I appreciate your thoughtfulness in this matter. Again thank you very much.

I purchased this unit to replace an older model that reached its maturity date. This one has a 10 year battery so I don't have to hassle with changing batteries. So far so good. Looks like a winner!

Dual sensor and 10 year battery

Reviewed: 02/18/2019 by Tom S

In California, the law requires 10 year batteries on non-wired detectors, and this is one of the few with dual sensors photoelectric and ionization - you need both types of detectors, why not have both in the same unit. Customer service is very friendly and helpful, plus shipping was included. What more can you ask for?

Easy to install to replace an older, ionization only smoke alarm. The base did have to be installed as the new alarm did not fit in the older first alert base. It was not, though, expected to fit. But it would've been a plus.

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.

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.
