Hardwired 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. Recommendations include:

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

What areas should I avoid installing a carbon monoxide alarm?

To prevent sensor damage or false readings, avoid the following areas:

• Harsh Environments: Garages, kitchens, furnace rooms, or any dusty, dirty, humid, or greasy areas.
• Temperature Extremes: Crawl spaces, unfinished attics, poorly insulated ceilings, and porches.
• Obstructions: Outlets covered by curtains, heavy furniture, or direct sunlight.
• Turbulent Air: Near ceiling fans, heat vents, air conditioners, fresh air returns, or open windows.

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

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

• Vehicles running in attached garages
• Furnaces and water heaters
• Clothes dryers, ranges, ovens, and stoves
• Fireplaces and space heaters
• Portable generators and charcoal grills

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 an explosive gas alarm or a combination carbon monoxide and natural gas alarm.

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

The chirp indicates a "low battery" condition. Battery powered CO alarms chirp for at least 30 days before losing power. AC powered alarms with battery backup will chirp indefinitely (assuming AC power is present) if the backup battery is low or removed until a fresh battery is installed.

Why should I go with a USI Hardwired CO Alarm?

USI Hardwired CO Alarms provide professional-grade protection through several key advantages:

• Multi-Threat Protection: Available as combination detectors that safeguard against CO, natural gas, and smoke.
• UL 217 8th Edition: New Sensing Plus models meet the latest requirements for fire detection while offering CO protection.
• Reliability: Superior false alarm resistance and equipped with battery backups for protection during power outages.

What is Ten Year Permanent Power?

USI Ten Year Sealed Battery Alarms include features exclusive to the brand:

• Dual Warranty: A 10-year warranty applicable to both the alarm and the battery.
• Activation Timing: Protection cycle begins upon activation, removing guesswork regarding longevity.
• Eco-Friendly: Lithium-free 10-year batteries for safer environmental disposal.
