Is Your Carbon Monoxide Detector Chirping or Beeping?

Your CO Detector may be reaching its UL mandated End of Life.  Approximately five years after activation, your Fireboy-Xintex Carbon Monoxide Detector will enter the EOL (End of Life) phase of its existence, beginning at 4 years and 11 months.


Underwriter’s Laboratories (UL for short), instituted a mandate approximately five years ago, outlining the End of Life Standard for Carbon Monoxide Detectors to protect users from the danger of boat operation without accurate means of detecting this potentially deadly gas. The first of this series of Carbon Monoxide Detectors were shipped from Fireboy-Xintex to our boat builders, dealers, and retailers in March of 2010, meaning their five-year expiration date is drawing near.
