What features should I look for when I select a CO detector?
  • The Underwriters Laboratory (UL) symbol. This symbol means that the detector has met the recommended safety standards of the American National Standards Institute.
    CO detectors with an audible alarm.
  • AC/DC powered detectors. This type of detector will provide coverage during a power outage.
  • CO detectors that have a digital readout. This will allow you to determine how you should respond. A high readout requires immediate evacuation of the home and possibly medical attention. A lower reading gives you the opportunity to contact your utility company.
