The First Alert Smoke and Carbon Monoxide Alarm has a slim profile, designed to blend more fully into the wall and out of sight. It offers the same functionality you expect from First Alert with a new design that takes up less space. The battery-operated smoke and carbon monoxide detector alerts you to possible smoke or carbon monoxide and can be installed anywhere, no wires required.
A photoelectric sensor detects smoke from slow smoldering fires, while reducing the number of false of alarms due to cooking smoke or steam from a shower. The advanced electrochemical sensor detects carbon monoxide leaks from multiple sources, including faulty fuel-burning appliances. The combination smoke and CO detector provides monitoring for both conditions in one streamlined device.
