Is Your Home Safe from Carbon Monoxide?

Millions of CO alarms in New York City may have reached the end of their useful life. In November 2004, New York City’s Local Law 7 went into effect requiring residential and commercial housing owners to install carbon monoxide alarms in the sleeping areas of all homes, apartments, schools, hospitals and educational facilities that have fossil-fuel burning equipment including furnaces, boilers, water heaters and fireplaces.

It’s estimated that more than 1 million CO alarms installed at that time have already or will soon reach the end of their useful life, and will begin beeping every 30 seconds.

Once an alarm sounds this end-of-life warning, it will not detect carbon monoxide. Consumers will need to replace their CO alarms immediately!

A Working CO Alarm is the Only Safe Way to Detect this Silent Killer

  • CO alarms monitor your home 24 hours a day, seven days a week, and are designed to provide accurate readings throughout the life of the alarm.
  • Like all other household appliances, CO alarms don’t last forever.
  • Unlike the instruments used by home maintenance and fire professionals, residential CO alarms cannot be calibrated periodically to verify accuracy. 

Underwriters Laboratories (UL) requires all CO alarms have an end-of-life warning

  • A residential CO alarm must have a defined end of life.  As of 2009, UL requires all CO alarms to have an audible warning that sounds when an alarm reaches the end of its proven life.
