Is it true that all pneumatic line type heat detectors must be tested for leaks and proper operation?

Pneumatic line type heat detectors rely on the expansion of gas within a sealed system to sense temperature changes. Regular testing for leaks and ensuring proper operation is essential for the reliability of these detectors. If there are any leaks in the system, the detector may fail to respond correctly to temperature changes, which can result in a delayed or nonexistent alarm during a fire situation. Consequently, maintaining the integrity of the pneumatic line is critical for effective fire detection.

Moreover, regular testing and maintenance are typically mandated by safety codes and standards to ensure that all fire alarm systems remain functional and can effectively protect life and property. Therefore, all pneumatic line type heat detectors must indeed be tested for leaks and proper operation as part of a comprehensive maintenance routine.
