When Do I Replace My Alarms?
Replace your smoke alarms every 10 years. Smoke alarms wear out over time. Although well-maintained alarms typically last about ten years, if you don't know when your alarms were installed, or if they are approaching 10 years, replace them now.
Learn MoreWhat Alarm Type Do I Choose?
It is important that your home is protected from smoke, fire, carbon monoxide and gas. First, decide if you need a hardwired, battery operated or plug-in alarm. Then, determine the sensor type by the area you are trying to protect and the size of your home.
Learn MoreWhere Do I Install My Alarms?
Install smoke alarms in the immediate area of any bedrooms. Additional smoke alarms should be placed on every floor. Carbon monoxide alarms should also be installed on every floor and near fuel-burning appliances, fireplaces or attachd garages.
