Commissioning & Integrated System Testing
Modern buildings rely on multiple fire protection and life safety systems working together: sprinklers, alarms, smoke control, elevators, and access control. DGA Consulting provides fire protection system commissioning and integrated testing for new construction and major renovations across New York, New Jersey, and Pennsylvania, verifying systems as a whole before the AHJ asks for proof.

What’s included
What commissioning and integrated system testing includes
DGA Consulting provides fire protection system commissioning and integrated testing for new construction and major renovations across New York, New Jersey, and Pennsylvania. The firm’s licensed Professional Engineers verify that individual systems — sprinklers (NFPA 13), fire alarms (NFPA 72), and the systems they connect to — are installed correctly per NFPA 3, then prove they perform together through integrated testing per NFPA 4.
Commissioning plans
Written plans defining scope, responsibilities, and acceptance criteria per NFPA 3.
Integrated testing (NFPA 4)
End-to-end testing of interconnected fire protection and life safety systems: alarm initiates, smoke control responds, elevators recall, doors release.
Test documentation
Complete records of every test, result, and deficiency resolution for the AHJ and owner. These records become the baseline for the NFPA 25 inspection, testing, and maintenance program going forward.
Deficiency tracking
Systematic punch-list management through final acceptance.
Owner training support
Documentation and walkthrough materials so building staff understand the systems they are inheriting.
When it applies

- Assembly, healthcare, and large commercial projects under the IBC and local amendments.
- Major renovations adding or modifying interconnected fire protection and life safety systems.
- Owners who want integration failures caught before occupancy, not after.

FAQ
Frequently asked questions
What is the difference between NFPA 3 and NFPA 4?
NFPA 3 covers commissioning of fire protection and life safety systems, which is the overall verification process. NFPA 4 covers integrated testing specifically: verifying that interconnected systems respond correctly together.
Is integrated testing required by code?
It depends on the jurisdiction and the code edition adopted. Adoption is growing, and the firm confirms the requirement for each project.
Can the firm commission systems designed by someone else?
Yes. Third-party commissioning by an independent engineer is standard practice and often preferred.
Which states are you licensed in?
The firm’s engineers are licensed fire protection engineers in New York, New Jersey, and Pennsylvania.
