In a CO2 operational test, nondestructive tests are required on detection devices and actuation devices.

• A. Destructive tests
• B. Nondestructive tests
• C. Functional tests only
• D. Visual inspections

Answer: (B)

Testing detection devices and actuation devices in a CO2 system must be nondestructive so you can verify proper operation without damaging the equipment or triggering an actual discharge. Nondestructive testing allows you to confirm that detectors respond to the appropriate signals and that release actuators engage correctly when commanded, using test signals, simulated inputs, electrical checks, and mechanical movement checks. This keeps the system ready for service and avoids unnecessary wear or damage. Visual inspections alone don’t prove functional performance, and destructive testing would damage components and isn’t appropriate for life-safety equipment.
