Smoke Alarms

One of the most important pieces of fire safety equipment we have in our homes is the smoke detector. Here a few quick tips to make sure yours are ready to alert you in the event of a fire:

  • Test regularly, the U.S. Fire Administration (USFA) recommends that we test our smoke detectors monthly, to some that may seem excessive but it’s crucial that if there is a fire that our smoke detectors work properly.
  • Replace the batteries twice a year. A good rule of thumb is to replace the batteries in our smoke detectors every time we change the clocks for daylight savings (twice a year).
  • Some newer models have a sealed 10-year lithium battery that doesn’t need to be replaced. Although these cost a little more than the standard alarms, you’ll save money not buying replacement batteries and have the peace of mind knowing they will work when needed.
  • The value of interconnected alarms. Many homes have interconnected smoke detectors, meaning when one goes off they all go off. This can be a huge advantage, especially at night if something were to happen.
  • Smart detectors: Nest protect and First Alert One-Link are examples of connected smoke detectors that work with an app to alert you of activation even if you aren’t home. Nest Protect alarms also have some cool additional features like night light settings.
