How often should fire alarms generally be replaced according to regulations?

Fire alarms are typically required to be replaced every 10 years according to most regulations and manufacturer guidelines. This timeframe is based on the understanding that the sensitivity of smoke detectors can diminish over time due to dust, dirt, and other environmental factors, potentially leading to reduced effectiveness. Additionally, components within the alarm can degrade, which may not allow them to respond appropriately to a fire situation.

By adhering to a 10-year replacement guideline, property owners help ensure that fire alarms maintain optimal performance, thereby enhancing safety for occupants. This regulation emphasizes the importance of regular maintenance and replacement to ensure that fire safety systems remain reliable over long periods.
