Review on 🚨 FIRST ALERT Carbon Monoxide Alarm: BRK CO250 with Battery Operated Detector & Two Silence Features - Top Safety Solution by Sam Lee

This detector matches the mounting screw pattern on the unit I am replacing and will help avoid drilling more holes in the wall. Unfortunately, like most currently on sale, this device is only 85dB and there's a good chance it won't wake you up if you're sleeping in a different room. It protects your hearing, but it's not as loud as devices from the past. I don't know what you think. Taking the subway to and from work is probably at greater risk of hearing damage than random false alarms. When a real alarm goes off, you want something loud to get your attention. If someone knows a device that is louder than 85 dB, please write.
