What is the typical life span of a smoke detector?

The typical lifespan of a smoke detector is approximately 10 years. This duration is based on the general guideline provided by manufacturers and safety organizations, which recommend that smoke detectors be replaced every decade to ensure optimal performance and reliability. Over time, the sensors within smoke detectors can degrade, and their effectiveness in detecting smoke and fire hazards may diminish. Therefore, replacing smoke detectors every 10 years not only follows safety protocols but also significantly enhances the safety of occupants in residential and commercial buildings. Regular maintenance, including testing and cleaning, should also be conducted throughout the life of the detector to maximize its functionality during emergencies.
