Plug In 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. It should be noted that many states are now requiring the installation of a carbon monoxide alarm inside of each bedroom. Carbon monoxide alarms should also be installed on every level in multiple story dwellings. If you have a basement, install a carbon monoxide alarm at the top of the basement stairs, and in each separate sleeping area. Carbon monoxide alarms should also be placed at least 15-20 ft. away from furnace or fuel burning heat sources.

What areas should I avoid installing a carbon monoxide alarm?

Proper placement is critical. Avoid installing alarms in the following areas:

• Environments: Garages, kitchens, furnace rooms, or any dusty, dirty, humid, or greasy areas.
• Temperature Extremes: Crawl spaces, unfinished attics, un-insulated or poorly insulated ceilings, and porches.
• Obstructions: Outlets covered by curtains, heavy furniture, or other obstructions.
• Turbulent Air: Near ceiling fans, heat vents, air conditioners, fresh air returns, or open windows where blowing air may prevent CO from reaching the sensors.

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

Carbon Monoxide is produced during incomplete combustion of fuel. Common sources include:

• Vehicles running in an attached garage.
• Furnaces, clothes dryers, and water heaters.
• 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. However, USI Plug-In Combination Alarms are designed to detect both carbon monoxide and natural gas.

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

A chirp indicates a "low battery" condition. Battery powered CO alarms chirp for a minimum of 30 days before losing power. AC powered alarms with battery backup will chirp indefinitely if the battery is low or removed, provided AC power is present. Approved replacement batteries are listed on the back of each alarm.

Why should I go with a USI Plug-In CO Alarm?

USI Plug-In Carbon Monoxide Alarms offer extreme flexibility and safety features:

• Easy Installation: Easily inserted into an outlet with no additional wiring necessary.
• Dual Sensing: 120v versions are capable of sensing both carbon monoxide and natural gas (methane).
• Battery Backup: Includes a 9v battery for continued coverage during power outages.
• Microprocessor Intelligence: Eliminates nuisance alarms to ensure you are warned of actual threats.
• End of Service Warning: Alerts you when it’s time to replace the unit (approximately 7 years after activation).
