Dual Sensors Guard against Danger

Combination Smoke and Carbon Monoxide Alarm features a photoelectric sensor that detects the smoke most commonly produced by smoldering fires, providing sensitive detection while minimizing false alarms from cooking smoke or shower steam. The advanced electrochemical CO sensor detects carbon monoxide leaks from multiple sources, such as faulty fuel-burning appliances, blocked chimneys, and generators running inside or too close to homes.

Easy to install:

Turn the alarm body counterclockwise and take off the bracket.

Hold the bracket in the installation position as specified in the Recommended Locations, mark installation holes of the bracket with pencil.

Drill the two marked installation holes with a 3/16 inch (5mm) drill bit. Tap the two plastic gromments into holes with hammer.

Mount the bracket to the ceiling by inserting and tightening the supplied screws into plastic grommets.
