After installation, how frequently should sensitivity of smoke detectors be checked?

The recommended interval for checking the sensitivity of smoke detectors after installation is typically within one year. This timeframe allows for the maintenance of optimal sensor functionality and ensures that the detectors are accurately identifying smoke particles. Smoke detectors can become less sensitive over time due to dust accumulation, insect infiltration, or other environmental factors that may impair their performance.

Conducting these tests annually not only aligns with many national standards and codes but also helps in identifying any potential issues early, ensuring that the fire alarm system remains reliable and effective in safeguarding the environment it protects. This proactive approach is crucial for maintaining compliance with safety regulations and enhancing overall fire safety preparedness.
