Where should I install combination alarms?

Combination alarms should be placed inside of every bedroom and outside of areas where people usually sleep. Detectors should also be installed on every level in multiple story dwellings. If you have a basement, install a combo alarm at the top of the basement stairs. These should also be placed at least 15-20 ft. away from furnace or fuel burning heat sources.

What areas should I avoid installing a combination alarm?

Do not install combination alarms in garages, kitchens, furnace rooms, or in any dusty, dirty, humid, or greasy areas. Avoid direct sunlight, crawl spaces, unfinished attics, and turbulent air near ceiling fans or open windows. Blowing air may prevent carbon monoxide from reaching the sensor.

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

Carbon Monoxide is produced during incomplete combustion of fuels like natural gas, charcoal, gasoline, or wood. 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 combination alarms detect explosive gas leaks?

No, not unless it is specifically marked as an explosive gas alarm. To detect explosive gas, you'll need a specific explosive gas alarm. The USI Store features combination carbon monoxide and natural gas alarms designed for this purpose.

Why should I choose a multi-threat combination alarm?

A typical home is vulnerable not only to fire but also to the silent, odorless killer, carbon monoxide, and the explosive potential of natural gas leaks. Rather than managing three separate devices, a combination alarm simplifies installation and ensures all three dangers are being monitored simultaneously.
