6. For smoke alarms, it is generally recommended to replace them after 7-10 years, as over time, the sensors start
to loose their sensitivity (due to contamination and degradation of components). Also, as for any other
electronics devices, the risk of electrical component failure increases over time, and thus the recommendation
for a safety device is to replace them within 7-10 years.
