Pneumatic line-type detectors shall be tested for leaks and proper operation at 6 month intervals.

Pneumatic line-type detectors shall be tested for leaks and proper operation at 6 month intervals.

• A. False
• B. True
• C. Sometimes
• D. Never

Answer: (A)

Testing the leaks and proper operation of pneumatic line-type detectors is required on an annual basis, not every six months. These systems rely on a pressurized sensing line, so maintaining line integrity is crucial to prevent drift, missed alarms, or false alarms. A yearly functional test verifies that the detectors respond correctly and that the line pressure remains within specification. After commissioning or following any service, you may do additional checks, but six-month intervals are not the standard requirement.
