As some of Rogers, developments are reaching the 10-year mark so are the smoke alarms in those homes. Smoke alarms should be replaced every 10 years from the manufacture date. Over time, the sensors in the alarms become dusty and cloudy causing alarms to go off for no reason or to not alarm when intended. Smoke alarms should be installed on every level of your home, outside each sleeping area and inside each bedroom. There are two kinds of smoke alarms ionization – which detect flaming fires quickly and photoelectrical – which detects smoldering fires quickly. It is recommended to use both types or a combination alarm in your home. Smoke alarms should be tested monthly and batteries replaced at least every six months depending upon battery duration.
