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 ‘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.
The updated K10SCO model fits the same mounting plate as the original 10SCO alarm
Front-loading compartment makes it easy to replace the 2x AA batteries (included)
Clear LED to indicate normal operation, faults, and alarm condition
Loud 85dB alarm and different voice warnings specific to the danger detected
The Kidde KE10SCO is supplied with the following components.

The alarm was recommended by the British Gas boiler service man during my annual service. It is a quality product and alarms for CO2 & smoke
