An update on this very sad story from a few months ago…
“When we bought this house we bought new detectors. When we were changing the batteries and testing it, we thought we had been doing right, when in fact [our units] expired,”
Do you know the age of the alarms in your home? The sensors contained in both smoke alarms and CO alarms have a limited lifespan. The manufacture date can be found on the back of the alarm. When you buy new alarms, using a sharpie to write the date of purchase on the side of the alarm allows it to be easily seen.
