Alarm Is Not 85db Alarm

I brought this first alert CO615 becaz it said it alarmed at 85db, this is not case, I can barely hear this alarm. It would not wake me if I was sleeping and actually probably would never hear it if I were awake and not listening for it!

No False Alarms
Lo Battery Alert At Night
Best Uses
Outside Every Bedroom
I have two CO Dectors, one in the hall outside the fitsr floor bedroom/office and one outside the master bedroom upstairs. Each has provided trouble-free service. About the only thing I see as an issue, is that when the batteries start to go low the unit will chirp regardless of what time of the day or night it is. Tht can be disconcerting in the middle of the night as you stumble around looking for ths source of the occasional chirp. A ligt sensor which is very cheap would solve this issue easily. We also have wired/battery smoke alarms AND combunation photo-electric/ionization smoke detectors that are part of our total monitored alarm system. The CO detectors are stand alone but serve the purpose very well. The alarm should wake a sound sleeper. Be aware the newest detectors have a 10 year sealed battery that cannot be changed (you replace the entire detector every 10 years) so you don't have to change the batteries annually and the newest detectors should last twice as long.
How long have you owned it:
More than six months
Bottom Line
Yes, I would recommend this to a friend.

Not so fast, has some issues
Plugs In Wall
Battery Door Bad Design
Made By First Alert
Best Uses
I bought this based on CR recomendations and it is fine and I use it but, I would not recomend you buy this because the battery door is poorly designed and does not stay closed.<br />Also, and this is an issue with Kidde and other brands and smoke alarms too, the alarm sound, when it goes off, is LOUD to the point of hearing damage. OK, yes, we need that during a real alarm. But when you unplug it from the wall, it alarms off the battery at full horn! WHY don't the engineers make it so the full alarm ONLY happens when actual detection happens?!<br />Over the past 20 years, 75% of the First Alert smoke alarms I have bought have failed in the first 1-5 years. But I also bought Kiddes and, never had any problems with them so. I am now only buying Kiddes.
How long have you owned it:
