First Alert SCO7CN vs Kidde i9050

A low battery warning does not need to be full volumn and it does not need to sound like a smoke or CO warning! When the alarm is blasting one naturally assumes leaving the area is the best course. So battery warning drives one from the building? Inappropriate design. BTW Batteries do not always last a year even when installed fresh so expect randomly timed adrenaline rushes, Random alarms seem the nature of all the smoke alarms I've ever lived with and this unit does occasionally blast one out. Bought and installed five of these and never could set the location so that is a wasted feature

I have better quality smoke & carbon monoxide alarms installed. Ipurchased these alarms to fillon the gap in coverage.

These are fine, they do the job. However, when you put the battery in it goes through a setup where you can pick the room that it’ll be installed (so the alarm will say “there’s smoke in the living room”). Anyways, the setup volume is full blast alarm loudness. Why does the setup menu have to be so loud?! Even with ear plugs in, it’s still too loud

Replaced all the smoke alarms in our house. I wish there weren't exterior blinking red lights that I see when going to sleep.

I found a review on Android Central that claimed this alarm connects to the wifi and sends you email alerts. I should have read more closely when I ordered it, because the information on the product on Amazon says nothing of the kind. I should have known that the price was too good for a unit that supposedly connects to the wifi. They seem good quality for what they are

One in each living space, one outside of each bedroom, one in the kitchen and some in the basement, including the laundry room were essential. Don’t forget the CO2 detectors! And plug them in low because CO2 is a heavy gas.

I not only wanted to get a smoke detector, but a carbon monoxide detector as well. This fit the bill as it is both. Works as expected.

I wanted to order specific replacement CO detectors at the same time and take full advantage of the discount, but the website doesn't carry ALL of the Kidde products -- not-so-good.
