Smoke detectors listed exclusively for door release service can be used in which scenario?

Smoke detectors that are listed exclusively for door release service are specifically designed and approved for that particular function, which is to initiate the release of door hardware during an emergency situation, such as a fire. Their primary purpose is to control doors or barriers rather than to provide comprehensive fire protection in open areas.

Given their specialized function, it is important to recognize that these detectors should not be deployed for open area protection, which requires different types of smoke detectors capable of detecting smoke and heat across larger spaces. Open area protection typically involves a different regulatory and operational framework, ensuring safety measures are in place across wide zones, and it necessitates detectors that are specifically tested and certified for broader fire safety responsibilities.

Therefore, the notion that these detectors cannot be used for open area protection aligns with the understanding of their limitations and intended use. Their restrictions ensure that fire safety measures remain effective and appropriate for different environments, emphasizing the importance of using the right types of detectors for the right applications.
