Installation
Where to Install
- The National Fire Protection Association (NFPA) recommends that a CO alarm be centrally located outside of each separate sleeping area near the bedrooms.
- For added protection, install additional CO Alarms in each separate bedroom and on every level of your home.
- If your bedroom hallway is longer than 40 feet (12 meters), install a CO Alarm at BOTH ends of the hallway.
Single-level Home
- Install at least one CO Alarm near or within each separate sleeping area.
- For added protection, install an additional CO Alarm at least 20 feet (6 meters) away from the furnace or fuel-burning heat source.
Multi-level Home
- Install at least one CO Alarm near or within each separate sleeping area.
- For added protection, install at least one CO Alarm on each level of the home.
- For added protection, install an additional CO Alarm at least 20 feet (6 meters) away from the furnace or fuel-burning heat source.
Mobile Homes
- Install CO Alarms on inside walls ONLY. Uninsulated outside walls and roofs of mobile homes often transfer heat and cold from outdoors.
- The Alarm should be located at least 6 inches (152 mm) from all exterior walls and at least 12 inches (305 mm) from supply or return vents.
How to Install
- In garages, kitchens, furnace rooms, or in any extremely dusty, dirty, or greasy areas.
- Closer than 20 feet (6 meters) from a furnace or other fuel-burning heat source, or fuel-burning appliances like a water heater.
- Within 5 feet (1.5 meters) of any cooking appliance. In extremely humid areas.
- These areas include unconditioned crawl spaces, unfinished attics, uninsulated or poorly insulated ceilings, porches, and garages.
- In turbulent air, like near ceiling fans, heat vents, air conditioners, fresh air returns, or open windows. Blowing air may prevent CO from reaching the sensors.
- Outside the Mobile Home. In direct sunlight.
9V Battery
- Push and lift the battery door down to open.
- Install the 9-volt battery(included) inside the battery compartment as indicated.
- Make sure the “+” and “– ”ends of each battery are aligned properly.
- Ensure the battery is securely snapped into the terminals by pushing direction of the arrow in the diagram.
- Close the battery door.
