First Alert Carbon Monoxide Detector, Plug-In Alarm with Battery Backup, CO606, White, 1-Pack

My old units were 10 yrs old. Needed to be replaced and updated. This is not something to be ignored! Very easy to follow the directions for set up before plugging in. Takes a few minutes with indicator lights and beeps to keep you on track. Since I replaced them they've been trouble free. No problems.

These manufacturers know how to put a great product together and also how to package it. Our previous First Alert carbon monoxide detector from 2019 started chirping 5 chirps. A Google lookup indicated it was indicating the end of its service life. Wow! Pretty cool. So I stayed with First Alert for replacing our two units. Both arrived in under a day. And you know how most plastic wrapped items are difficult to open without slicing your fingers? Not these. The back of the package has a perforated pulldown tab to open easily. And they even provide a new battery. Totally legit Company placing the customer FIRST, for real.

Priced rough and gives me a sense of piece.

Read this if you want to save your time reading the too much info in the manual. Its overwhelming. This kind of stuff there should be a separate manual that features only the important instruction. - first and foremost 4 star only coz I wanted to buy the 3 pcs pack but good thing Ive read some comments with same complaints that they bought 3 pcs but they received only 1 pc. That must be a hassle and inconvenient to raise a complaint so I just bought 2 separate item and I am planning to buy another 2. - REASON WHY I BOUGHT THIS BECAUSE IVE READ: that First Alert is a reputable brand known for fire and CO safety products. Battery Backup: Works during power outages essential for 24/7 protection. Easy to install, no hardwiring needed. And the most important is it is "UL Certified" it Meets safety standards set by Underwriters Laboratories. Compared to other co detectors in amazon. These certifications mean the CO detector: •Has passed rigorous, standardized safety tests •Will reliably detect dangerous levels of carbon monoxide •Won’t give false alarms or miss actual danger And when you buy this whether u like it or not you have to put the battery first and plug it. Coz if you dont put the battery and just plug it directly there will be a chirp sound every 30 seconds or so, and I found out thats an indication you need to install the battery. My bad I did not read the manual coz it overwhelms me a lot coz its too much to read for a supposed to be direct instructions only. So I tested my 2 first alert and it works. And you have to test it at least once a week. How I know this really works? I dont know I just have to trust the brand. And not wishing to have CO leak in our house. But this will bring us peace of mind knowing we have a CO detector at home esp so many sad cases about co leak in the house and people die. BE CAREFUL Y'ALL!

Appears to be really good. We have it located in our dining room.

I got this item to replace a 10 year old same model First Alert carbon monoxide detector. Old detector working fine but I decided to replace it. Fortunately I never had a CO leakage but I checked the test button every few weeks to ensure it was working.

Instructions were clear. Easy to install with a drill bit. Fits flush to the wall. Battery worked great.

The inclusion of a 9V battery right out of the box is a thoughtful touch. It gives me peace of mind knowing that the detector is ready to go, and the added battery backup ensures continuous protection even during power outages. I tested the detector when it arrived, and everything checked out. The ease of setup and the immediate functionality straight out of the box impressed me. The clear instructions provided made the installation process a breeze. As a consumer, the First Alert brand has always been synonymous with reliability and trust. This CO detector is no exception. It reinforces my confidence in the brand, and I appreciate the commitment to delivering high-quality products that prioritize safety... at a reasonable price. The white design seamlessly blends with my home decor, making it unobtrusive. The compact size ensures it doesn't take up much space. In summary, the First Alert CO605 Carbon Monoxide Detector is a stellar product that offers peace of mind, reliability, and ease of use. I highly recommend it to anyone in need of a top-notch carbon monoxide detector. Five stars – well deserved!

Ended up getting this sooner than expected. It is so easy to ready and replace the old one. Very happy with it.
