Acceptance tests for SHS are performed during which phase per typical codes?

Acceptance tests for SHS are performed during which phase per typical codes?

• A. Only after major incidents
• B. Never
• C. During initial installation commissioning
• D. Only after system upgrades

Answer: (C)

Acceptance tests for Special Hazards Systems are performed during the initial installation and commissioning phase to verify that the system, as installed, meets the design intent and performance criteria before it is accepted and placed into service. This testing window ensures all components—detection, alarms, release actuators, suppression agent quantities, and interlocks—work together correctly and respond in the intended sequence. It also confirms integration with the building’s monitoring and control systems and provides documented evidence that the system meets the applicable codes and standards. This proactive verification is not about reacting to incidents or applied after-the-fact changes; it’s the formal check right after installation to make sure the system is ready for operation. If a system is subsequently upgraded, portions may undergo re-testing, but the established practice is to conduct acceptance testing during commissioning of the installed system, not as an afterthought.
