In testing, which activity focuses on validating that each device operates correctly?

• A. Function test
• B. Acceptance test
• C. Commissioning test
• D. Performance test

Answer: (A)

Checking that every device works on its own is what a function test targets. It validates that each component—like a smoke detector, manual pull station, or notification appliance—operates correctly when tested, confirming basic functionality such as sensing, triggering, and audible signaling. This focus on individual device behavior differentiates it from other tests: acceptance tests look at whether the system meets user requirements and works as a whole, commissioning tests verify proper installation and integration, and performance tests assess how the system performs under specified conditions or loads.
