  • What's Included
  • Keep your home safe from dangerous carbon monoxide and natural gas leaks with Universal Security Instruments' IoPhic Home Hardwired Carbon Monoxide and Natural Gas Alarm. This 2-In-1 alarm is a hardwired wall, or ceiling, mounted alarm system equipped with Microprocessor Intelligence temperature control, humidity control, and false alarm control technology to provide consistent alarm sensitivity and performance without interference from common nuisance alarms such as dust, debris, paint fumes, shower steam, cooking smoke, and household chemicals and cleaners.

    The 2-In-1 alarm system can also be interconnected with other similiar alarm systems--so when one alarm goes off on the other side of the house, all interconnected alarms will alert you to the gas leak. When it comes to these hazards, small or big, false or true, early detection and warning can give you the few seconds needed to get to safety.

    The alarm that originally detects the presence of carbon monoxide and, or, natural gas leaks can be found by simply silencing an alerting alarm and pressing the Test/Silence button to sound the original alarm. The alarm emits a loud 85 dB audible alert that can be heard easily and informs you where the danger is coming from within the home.

    The alarm's interconnectivity, false alarm control, temperature control, humidity control, and loud sound offers you value and quality for protecting yourself, your home, and loved ones.
