How often are non-restorable spot type detectors tested after the first 15 years?

Non-restorable spot type detectors require periodic testing to ensure their reliability and effectiveness in detecting fire. After the first 15 years of installation, these detectors should be tested every 5 years. This timeframe is established to reflect the aging of the devices and the potential for degradation in their performance over time.

Regular testing is crucial because detectors may not function as intended due to factors such as dust accumulation, environmental influences, or electronic component wear. By adhering to a 5-year testing interval, facility managers can mitigate risks associated with failing detectors and ensure that fire safety systems are operational when needed.

This practice aligns with industry standards and guidelines which emphasize the importance of proactive maintenance and testing protocols over extended periods, ensuring reliability and compliance with safety regulations.
