10-Year Battery Natural Gas and Carbon Monoxide Alarm Product Description

The Universal Security Instruments 10-Year Battery Natural Gas and Carbon Monoxide Alarm offers complete home protection against gas leaks and carbon monoxide without any wiring. Powered by a 10-year sealed battery, this standalone natural gas detector stays active during power outages. Advanced sensors quickly catch methane leaks from stoves, furnaces, and gas lines, giving you an early warning before hazardous gas builds up.

An integrated electrochemical sensor constantly checks for invisible carbon monoxide, uniting two critical gas protection systems into one compact wall unit. Choosing a 10 year battery power natural gas alarm allows for flexible placement near gas appliances or sleeping areas without needing an open outlet or complex wiring. Upgrading your home protection with a dedicated natural gas alarm ensures early warnings, code compliance, and decade-long peace of mind with zero annual battery swaps.


Key Features & Benefits

  • Dual Gas & CO Sensing: Detects explosive natural gas (methane) and toxic carbon monoxide in a single compact device.
  • 10-Year Sealed Battery: Operates on an internal 10 year lithium battery to ensure continuous, maintenance free monitoring without battery replacements.
  • Fast Wireless Installation: Surface mounts easily onto walls near fuel-burning appliances with no hardwiring or open outlets required.
  • Test / Silence Button: Easily run weekly diagnostic tests or temporarily mute non-emergency alerts with a single press.
  • Loud 85 dB Alarm: Emits a powerful 85 dB siren to ensure immediate notification during a natural gas leak or carbon monoxide event.
  • End-of-Life Alert: Signals after 10 years to let you know exactly when it is time to replace the unit.

Industry Standards & Compliance

This alarm is certified to meet strict residential safety requirements:

  • ETL Listed: Safety tested to UL 1484 standards for residential gas detectors and UL 2034 standards for carbon monoxide safety.
  • NFPA Compliant: Satisfies NFPA 720 code guidelines for residential carbon monoxide and gas monitoring devices.
  • Federal Housing Standards: Meets all FHA and HUD regulatory standards for residential safety equipment.
  • Residential Approved: Ideal for single-family homes, townhomes, apartments, and areas near gas stoves, furnaces, or water heaters.

(Note: Install this combination alarm on a wall at the proper height according to local code and manufacturer guidelines, as natural gas rises toward the ceiling.)

How does the Universal Security Instruments 10-Year Natural Gas and Carbon Monoxide Alarm work?
The Universal Security Instruments USI/NGCO/10YR provides dual protection by continuously monitoring for methane (natural gas) leaks and dangerous carbon monoxide (CO) levels. Featuring a built-in 10-year sealed lithium battery, this natural gas detector operates 24/7, even during electrical power outages.
Where should I install a battery-powered natural gas alarm?
Natural gas (methane) is lighter than air, it rises toward the ceiling. For optimal detection, mount the unit high on a wall. This would typically be within 12 inches of the ceiling, near potential gas sources like gas stoves, furnaces, or water heaters. Avoid installing natural gas alarms directly above appliances or in drafty corners where airflow might delay leak detection.
Does the USI/NGCO/10YR natural gas detector comply with residential safety standards like UL 1484?
Yes. The USI 10 Year Natural Gas and Carbon Monoxide Alarm is engineered to meet UL 1484 standards for residential gas detectors as well as UL 2034 for carbon monoxide safety. Its calibrated sensor provides early warning against gas accumulation and includes a loud 85 dB horn with a visual LED alert to notify residents before explosive thresholds (LEL) are reached.
How do I test or quiet a false trigger on my natural gas alarm?
To test your natural gas detector, press and hold the front Test/Reset button until the 85 dB siren sounds. If a non-hazardous trigger occurs (such as temporary household aerosols or cooking vapors), press the Auto Silence button to temporarily quiet the alert while venting fresh air through the space.
How do I know when it is time to replace my natural gas and carbon monoxide alarm?
The Universal Security Instruments USI/NGCO/10YR features an automatic end-of-service life indicator. Exactly 10 years after activation, the unit will issue an audible chirp and visual code indicating that the sealed battery and gas sensors have reached the end of their operational lifespan, signaling that the unit should be replaced with a new natural gas detector.
