Combination Carbon Monoxide and Smoke Alarm 10 Yr Warranty - Kidde K10SCO
The Kidde K10SCO provides both smoke and carbon monoxide detection from one space-saving unit, and is backed by a 10 year warranty. Powered by 2 x AA alkaline batteries, this combined alarm effectively detects smoke with its optical sensor and uses an electrochemical sensor for deadly carbon monoxide which is undetectable by all human senses. Featuring voice alerts, the alarm will announce either 'FIRE! FIRE!' or 'WARNING! CARBON MONOXIDE!' depending on which danger has been detected, combined with an alarm beep sequence. If replacing an older model (10SCO), this unit will fit on the existing baseplate.

Had one of these 10 years ago, and it's performed very well, so I'm replacing it with the same model.
Simple and easy to use and install.
I would recommend this product.

Good product, and with the talking warning it's far better than just beeps. Excellent next day delivery as well.
