USI 10-Year Battery Natural Gas & Carbon Monoxide Alarm: Dual Protection & Code Compliance

Built to protect against both combustible methane leaks and silent carbon monoxide, the USI/NGCO/10YR combination natural gas and carbon monoxide alarm delivers 10 years of maintenance-free, battery-powered safety.

Dual Detection: Combination Natural Gas & Carbon Monoxide Sensing

Protecting a home against combustible fuel leaks and toxic fumes traditionally required multiple devices. The USI/NGCO/10YR functions as an advanced combination natural gas and carbon monoxide detector, integrating a sensitive methane sensor with a precision electrochemical CO sensor in a single unit.

This combo natural gas and carbon monoxide alarm alerts occupants to methane buildups well before reaching explosive thresholds, while continuously tracking carbon monoxide emissions from heating equipment, dryers, and stoves.

10-Year Sealed Power & Code Compliance

Powered by a sealed lithium battery, this combination natural gas and carbon monoxide detector offers continuous operation through severe storms and utility blackouts without wiring or outlet dependence:

  • UL 1484 & UL 2034 Listed: Fully certified to rigorous standards for combustible methane gas and carbon monoxide safety.
  • Building Code Compliant: Satisfies emerging residential gas detector mandates including NYC Local Law 157 and NFPA 715 guidelines.
  • Optimized Placement: Mount 4 to 12 inches below the ceiling near gas appliances to catch rising methane without nuisance alarms.

Frequently Asked Questions

Where should a combination natural gas and carbon monoxide alarm be installed?

Natural gas is lighter than air and rises rapidly. Mount your combination natural gas and carbon monoxide alarm on a wall 4 to 12 inches below the ceiling and within 10 to 15 feet of gas-burning appliances like water heaters, boilers, or stoves.

Does a standard carbon monoxide detector also detect natural gas?

No. Traditional carbon monoxide detectors cannot sense natural gas. Protecting against both threats requires a dedicated combo natural gas and carbon monoxide alarm like the USI-NGCO-10YR.

Does this combo natural gas and carbon monoxide alarm comply with NYC Local Law 157?

Yes. The USI/NGCO/10YR meets the UL 1484 standard required by New York City Local Law 157 and NFPA 715 guidelines for residential combustible fuel gas detection.
