Caution: Smoke Detectors Have A Shelf Life

smoke-detector-shelf-life

Smoke detectors expire. Over time they lose sensitivity. The last thing you want is a weak smoke detector in your room while sleeping soundly at night.

Here’s what you need to know…


 
The smoke detector ‘works’ largely unnoticed while on the ceiling or walls while it constantly and continuously measures the air around it – just waiting to alarm.

   

It works hours, days, weeks, months, years – never ending.

At least until one of two things happen…

1. The batteries run dead.
2. It’s shelf life expires.

Note: A good habit to get into for replacing smoke detector batteries is during every New Year.
January 1 seems like as good a day as any…

But did you know that smoke detectors lose their effectiveness over time?

The U.S. Fire Administration says most smoke detectors installed today have a life span of about 8-10 years. After this time, the entire unit should be replaced.

It is a good idea to write the date of purchase with a marker on the inside of your smoke detector’s (battery compartment) so you will know when to replace it. Some of the newer detectors already have the purchase date written inside.

 

About Smoke Detectors

There are many different brands of smoke alarms available on the market but they fall under two basic types: ionization and photoelectric.

Ionization alarms sound more quickly when a flaming, fast moving fire occurs.

Photoelectric alarms are quicker at sensing smoldering, smoky fires.

Dual Sensor alarms combine ionization and photoelectric into one unit.

Because both ionization and photoelectric smoke alarms are better at detecting distinctly different yet potentially fatal fires, and because homeowners cannot predict what type of fire might start in a home, you might consider installation of both ionization and photoelectric or dual sensor smoke alarms.

Dual Sensor Photoelectric and Ionization Smoke Alarm

Some smoke alarms are considered to be “hard-wired.” This means they are connected to the household electrical system and may or may not have battery backup. You should check yours…

You should have escape plans and make sure everyone in the household knows them.

Have several fire extinguishers. Consider one in the bedroom and one near the kitchen.

You should also install a carbon monoxide detector.
