First Alert SCO5CN

My hardware store has the I same item on the first alert and my carbon monoxide detector. $39.99 and the price I paid from Amazon was twenty to thirty...

The two supplied Duracell batteries were DOA. After replacing the batteries, the detector works fine.

This particular smoke/CO detector seems nice for a while, then starts the dreaded random beeping, which of course has to happen at 2:45AM. I had four of these at one point and after 1-2 years of service they all ended up issuing the beep sequence decoded as "unit defective - replace" which seems ter...

I selected this First Alert CO and Smoke detector alarm because my previous one exceeded its useful life. The new model features some improvements (easier to change batteries), but the package and the Amazon description say that the package includes batteries, screws and wall anchors, and user manua...

I bought three of these about 3 years ago. Install is easy. Two on the ceiling upstairs. One on the ceiling downstairs. The problem is 2 of the 3 have started to frequently go off for no obvious reason. They are excruciatingly loud--which would be fine if there was an actual fire. I am sick of being...

Battery life depends on battery manufacturer you are using and how often you test the alarms. Always test because alkaline batteries can leak and oxidize and corrode contacts and damage the alarm.

NO experience with how long the batteries last nor the noise level. CA state mandates when selling a home the seller must include these smoke and carbon monoxide alarms in ALL rooms. I simple satisfied the mandate by installing six (6) alarms at a out-of-pocket cost of $269.22...not including approx...

Installed in July and now I get a 3 beep message which tells me that I need to replace. Very disappointed. I updated this to 4 stars as I noted that I had a 7 year warranty and I called First Alert and they are sending me another one in a week. Still not impressed that it failed in a few months, but...

I bought this alarm because I have a ventless propane fireplace with fake logs. It did alarm when my fireplace was burning incorrectly, so it did it's job. I would recommend using a duracell battery for something as important as this. I recommend this alarm because CO kills many people each year and...

I ordered this by mistake as I should have ordered the one that can be hard-wired instead of only battery-operated, but that being said, I have had no issues with it at all.
