Commissioning Smoke-Control Systems

Commissioning and acceptance testing demonstrate that the final integrated system complies with the design and that any modifications were correctly and successfully incorporated, so that the result is a properly functioning system. The design engineer must be involved with the test-and-balance contractor, the mechanical contractor, electrical contractor, controls vendor and fire-alarm vendor.

Commissioning and acceptance testing demonstrate that the final integrated system complies with the design and that any modifications were correctly and successfully incorporated, so that the result is a properly functioning system. The design engineer must be involved with the test-and-balance contractor, the mechanical contractor, electrical contractor, controls vendor and fire-alarm vendor. Each component must be verified for operation, including:

Pressure differences. Differentials must be taken across every door and recorded.

Shutdown of air systems and damper closure. This sequence must take place with the correct initiation.

Restart. The system must restart automatically upon fire-alarm reset

Accessible openings in outside-air and return-air ducts must be installed so that actual automatic damper position can be observed. Relying on the damper-shaft indicating notch is an invitation to trouble. The owner’s engineering staff and maintenance personnel must be instructed-not only in the operation but in the design intent of a facility so that an understanding of systems operation is achieved.
