Most homeowners remember to change the batteries in their smoke, fire and carbon monoxide detectors every year, but how often do you replace the alarm unit itself?
According to the National Fire Protection Association, 85% of all fire fatalities occur at home, mostly at night when people are defenseless. A well-functioning smoke detector is your family’s first line of defense against being injured or even killed in a fire.
Since alarms can fail at any time, the electricians at STG Electric Services urge you to maintain a monthly testing schedule on both battery-operated and hard-wired units. You should also consider changing the detectors every time you move into a new residence, unless you know precisely when they were installed.
