It's a personal choice as to whether you install separate smoke and carbon monoxide (CO) alarms or a combination alarm. If the building code requires both smoke and CO alarms, it may be easier and more cost effective to install a single combination alarm.
Additionally, combination alarms save space in your home, and they mean you only need to test and change batteries in one device rather than two.
Properly installed and maintained, smoke alarms are one of the best and least expensive ways to provide an early warning when a fire begins. Smoke alarms save lives, prevent injuries and minimize property damage by alerting residents early to a fire hazard.
