Battery Operated Carbon Monoxide Alarms

Where should I install carbon monoxide alarms?

Carbon monoxide alarms should be placed inside of every bedroom and outside of areas where people usually sleep. Proper placement is essential for safety:

• Every Level: Install alarms on every level in multiple story dwellings.
• Basements: Place an alarm at the top of basement stairs.
• Heat Sources: Position detectors at least 15-20 ft. away from furnace or fuel burning heat sources.

What areas should I avoid installing a carbon monoxide alarm?

Do not install carbon monoxide alarms in garages, kitchens, furnace rooms, or in any dusty, dirty, humid, or greasy areas. Avoid areas subjected to temperature extremes (crawl spaces, porches) or turbulent air near ceiling fans and heat vents, as blowing air may prevent CO from reaching the sensors. Also, ensure outlets are not covered by curtains or heavy furniture.

What are some common sources of carbon monoxide (CO)?

Carbon Monoxide is produced during incomplete combustion of fuels like natural gas, charcoal, gasoline, wood, and oil. Common sources include:

• Vehicles in garages
• Furnaces
• Clothes dryers
• Ranges & Ovens
• Fireplaces
• Water heaters
• Space heaters
• Portable generators

Will carbon monoxide alarms detect explosive gas leaks?

No, not unless it is specifically marked as an explosive gas alarm. USI CO Alarms are single function and react to carbon monoxide only. To detect explosive gas, you'll need a dedicated or combination natural gas alarm.

Why does my CO alarm "chirp" approximately once every minute?

The chirp indicates a "low battery" condition. Battery powered CO alarms will chirp for a minimum of 30 days before losing power completely. AC powered units with battery backup will chirp indefinitely if the battery is low or removed until a fresh battery is installed.

What is Ten Year Permanent Power?

• 10 Year Dual Warranty: Coverage applies to both the alarm and the battery.
• Activation Timing: Protection cycles begin only upon activation, removing guesswork regarding performance life.
