FIRST ALERT Carbon Monoxide Alarm BRK CO250 Battery Operated Carbon Monoxide Detector With 9 Volt Battery & Two Silence Features, White, CO250B, 1-Pack

THIS IS NOT MADE BY FIRST ALERT! False description. Do not buy.

I removed this from packaging and removed the activation strip from behind the battery as instructed. When I tested the unit, it did not work. I returned it and they sent a replacement. The second one worked fine. Make sure to hit that "test" button before you screw it to the ceiling or wall and rely on it to save your life in the event of a co2 event.

We got this First Alert BRK carbon monoxide alarm simply because it is the same model that was already screwed into our ceiling.We are thankful that the same model still exists so that we can reuse the same screw holes.However, we are very disappointed that the new alarm is missing the warning sticker that tells people what to do when the alarm sounds. This sticker is supposed to go on the side of the alarm.It is also missing the sticker that goes inside of the alarm that informs people what the different number of beeps mean.Without these stickers, the alarm is so uninformative and people will not know what the beeps mean and what to do. Pretty useless.We cannot expect tenants to unscrew the whole alarm to go look at the back of it for instructions. It shouldn’t require unmounting the alarm.When the alarm went off for us, I only knew that it was the end of life and not CO because of those stickers. I definitely didn’t think about finding screw drivers to take off the alarm.In case of emergency, people shouldn’t be required to have screw drivers on hand.Please help and send us the missing instructional stickers.

This detector fits the mounting screw pattern of the unit I am replacing and that helps avoid drilling yet another set of holes in the wall.Unfortunately, this unit, like most now for sale, is only 85 dB and there is a good chance that it will not wake you up if you are sleeping in another room. It protects your hearing, but is not as loud as units from past years. I do not know what they are thinking. Traveling on subways to and from work probably exposes you to more hearing damage than an occasional false alarm. If a real alarm occurs, you want something loud to get your attention. If anyone knows of a unit louder than 85 dB, please post.

This detector comes packaged as BRK Brands. However there is a connection to First Alert as noted on the packaging, product, and both the BRK and First Alert websites. Thought it was a scam at first, but even my old First Alert alarm says BRK Brands on the back of it. So, buy with confidence. It is a no frills alarm. Oh ... and it came with a fresh Duracel battery.
