What to do when your carbon monoxide alarm beeps

Kidde CO

(NC) – You may find them annoying, but the beeps emitted from your carbon monoxide and combination smoke/CO alarms are really just doing their job: protecting your life.

They are high tech devices after all, so always read the product manual. Meanwhile here’s a quick primer, from leading manufacturer, Kidde, on what the most common CO alarm warning beeps are telling you. The explanations are based on their most popular models no matter whether your CO and combination alarms are battery powered, plug-in or hardwired.

Carbon Monoxide Alarms

If your CO alarm has a low battery, you will hear one quick beep every 15 seconds. One advantage of popular digital display CO alarms is that, in addition to the beep, you will also see “Lb” signifying “low battery” in the display window.

If your CO alarm has reached its end of life and needs to be replaced, you will hear one quick beep every 30 seconds. This is a requirement put in place by the Canadian Standards Association (CSA) in 2007. If the alarm has a digital display, in addition to the beep, you will also see “End” signifying “end of life” in the LED window.

If your CO alarm has detected the presence of carbon monoxide in concentrations greater than 70 parts-per-million (ppm), the alarm will sound in a repeating pattern of four short beeps followed by five seconds of silence. If you hear this beep pattern, assume an emergency situation and evacuate or move to a fresh air source immediately.
