Combination Smoke/Carbon Monoxide Alarms

2-in-1 protection from one reliable alarm.

Carbon monoxide and fire can make for a deadly duo, but Kidde makes it easier to protect yourself against both. Combination smoke and carbon monoxide alarms have sensing technologies that work together to detect fires and the odorless, colorless, tasteless gas known as CO – the silent killer. Each combination alarm includes the company’s patented Nighthawk™ electrochemical CO sensor.
