How long should a smoke detector last?

While you may think your smoke detector sits idle until smoke is detected, in reality it's constantly monitoring the air 24 hours a day. So an ionization smoke detector goes through 3.5 million monitoring cycles in 10 years. In a photoelectric smoke detector, a light operates 24 hours a day to check for smoke particles in the air. And just like any electrical appliance, the components of smoke detectors wear out over time. When a smoke alarm reaches 10 years of use, the potential of failing to detect a fire increases substantially. Replacing them after 10 years reduces the likelihood of failure.
