Smoke Alarm with Lithium Battery

First Alert 10-year Lithium Smoke Alarm

This unit features a ten-year non-replaceable lithium battery, which spares you from changing a battery each year, but this smoke alarm has only an ionization sensor, so it’s less effective at detecting smoky fires.

Reviews say this is a good choice if you want a detector with a very long battery life, but since it lacks a dual sensor, it is best used with a photoelectric detector.

The cost of a second detector can eat up the savings from not having to replace the batteries in this unit.

Setting up a fire escape route out of your home is a must if you have small children. Contact the local Fire Marchall's Office or you nearest Fire Station for help in planning your escape route from you home or apartment.
