The 5800COMBO is the industry's first professionally monitored, wireless, combination Smoke and Carbon Monoxide (CO) detector designed to help protect people and property. Using four sensing elements, the 5800COMBO provides true multi-threat detection and reacts fast to real danger-while helping to reduce false alarms.

A photo-electric chamber senses airborne smoke particulates while an electro-chemical sensor monitors the CO bi-product produced by slow smoldering fires.
