When Is Integrated Testing Required?

Integrated systems are defined as “a combination of systems that are required to operate together as a whole to achieve overall fire protection and life safety objectives”. The 2018 edition of NFPA 101, Life Safety Code is the first edition in which we see requirements for integrated testing of fire protection and life safety systems in accordance with NFPA 4, Standard for Integrated FireProtection and Life Safety System Testing.

Section 9.11.4 of NFPA 101 makes the general requirement for integrated testing, in accordance with NFPA 4, as required by Chapters 11 through 43, or where two or more fire protection or life safety systems are integrated.  As published, the NFPA 4 integrated testing process would have to be applied to many new or existing occupancies regardless of building size, construction type, occupant load, system complexity, or other operational or structural features.  The intent of NFPA 4, a testing protocol that verifies systems perform as intended, was not necessarily meant to be applied to every simple system.  It was intended for complex systems and structures, such as high-rise buildings and smoke control systems.

Multiple TIA’s (tentative interim amendments) were submitted, and approved, to provide guidance that meets the intent for the application and enforcement of an NFPA 4 integrated testing process.  The initial TIA (18-5) made the following two changes:
  • added section 9.3.5 – this requires smoke control systems that are integrated with other fire protection or life safety systems to be tested in accordance with an NFPA 4 process.
  • divided section 9.11.4 into two sections:
    • 9.11.4.1 – for basic testing, to ensure that all integrated systems receive testing to verify proper operation and function of the system
    • 9.11.4.2 – specifies systems that must be tested in accordance with the NFPA 4 integrated testing process

 The addition of 9.11.4.2 requires NFPA 4 integrated system testing in the following:
  • all smoke control systems integrated with other fire protection/life safety systems
  • all high-rise buildings with integrated systems
  • every 10 years in existing buildings

Testing Integrated Fire Systems




Integrated fire systems are those fire protection and life safety systems that "are required to operate together as a whole to achieve overall fire protection and life safety objectives." An example of an integrated system might be a fire alarm, fire sprinkler, elevator recall, and smoke control. When a fire is detected each of these items has a specific code required function to perform.  Integrated testing ensures that these systems all work flawlessly together. Integrated testing is to be completed as outlined in NFPA 4, Standard for Integrated Fire Protection and Life Safety System Testing.  Integrated system testing is also a function that should be part of the building commissioning plan.

This integrated testing is to be supervised and managed by an Integrated Testing Agent (ITa).  The ITa is responsible for planning, scheduling, documentation, coordination, and implementation of the integrated testing for all systems.  The ITa's first responsibility is to create a test plan.  The integrated testing plan provides guidance, direction, and time-frames for all systems personnel. 

This integrated test plan must include the following components:

  • Verification of proper installation per design documents
  • List of each system that is installed and is to be tested
  • All documentation for each system (as required by that systems code or standard)
  • List and contact information for all members of the integrated test team, their responsibilities, and a denotation of which individuals are required to be present for testing
  • List of all equipment required for testing
  • System input and output function matrix
  • Final system drawings and diagrams are to be listed and referenced in the testing plan and available on-site
  • Narrative description of test scenarios and procedures, and documentation and approvals for the AHJ
  • The extent of systems and system functions to be tested
  • Testing schedule
  • Future integrated systems test frequency

A thorough and complete integrated testing plan will keep everyone moving toward the same goal.  The plan will ensure that all items are properly tested, will work together, and all required documentation is accounted for.

The 5 Documents Commissioning Requires


The purpose of commissioning as stated in NFPA 3, Recommended Practice for Commissioning of Fire Protection and Life Safety Systems, is a "process that will ensure fire protection and life safety systems perform in conformity with the design intent".  To make this possible there are 5 required documents that must be created and referenced during the commissioning process.

  1. Owner's Project Requirements (OPR)
  2. Commissioning Plan
  3. Basis of Design (BOD)
  4. Operations and Maintenance Manuals (O&Ms)
  5. Closeout Package


NOTE: If you are not familiar with the commissioning process, I recommend you first read, Commissioning New Occupancies.

The most critical of these documents is the Owner's Project Requirements (OPR).  This is the driving document that all design, construction, testing, and operational decisions will be based on. The OPR should be created with input from the owner, building managers, and key stakeholders. The OPR should include:

  • Infrastructure requirements (roads, utilities, etc.)
  • Facility type, use, and dimensions
  • Occupancy classification, anticipated load and expected operations
  • Future expansion requirements
  • Codes and standards that apply to the facility (local, state, national)
  • Specific user/owner requirements
  • Training requirements
  • Warranty, operations, and maintenance information
  • Integrated system testing, installation, and maintenance requirements
  • Specific performance criteria that will be expected
  • Any "third-party" requirements

The Commissioning Plan provides the framework  for the building projects commissioning process.  The Commissioning Plan provides an overview of the project and outlines the process, system, and schedule to be followed.  All the required commissioning reports, inspections, and documentation will be included as part of this plan.  NFPA 3 recommends the following Commissioning Plan structure:
  • Introduction - an overview of the plan
  • Commissioning scope - identifies which building components, structures, and systems will be subject to, and included in the commissioning process
  • General project information - overview of the project, focus on key information, expectations, and deliverables. This should include references and overviews of the OPR and the BOD
  • Team contacts - contact information of all commissioning team members
  • Communications plan and protocols - provide direction as to the projects organizational structure and communication channels to be utilized
  • Commissioning process - detailed explanation and outline of commissioning and project tasks to be completed for all phases of the process
  • Commissioning documentation - listing of all documentation that will be required and utilized throughout the process
  • Commissioning schedule - specifies the sequence of operations, and outlines the timeframe, dates, and duration of commissioning and testing events


The decision-making process and an explanation of all systems and components are described narratively in the Basis of Design (BOD). The BOD should be created and included with the the project plan submittal to the AHJ.  A useful BOD will include the following components:

  • Applicable codes, standards, laws, and regulations (NFPA, OSHA, ADA, ASHRAE, etc.)
  • Building description
  • Fire protection/life safety system objectives and decisions
  • Alternative or performance based design, means, and methods
  • Testing criteria
  • Equipment and tools required

Operations and maintenance manuals (O&Ms) are to be provided to the building owner.  These O&Ms must be reviewed to ensure that they meet the OPR.


At the end of the construction phase, prior to the occupancy phase, a closeout package should be delivered to the building owner. The closeout package should include the following documents:
  • Compiled list of all deficiencies and resolutions
  • Operation and maintenance manuals
  • All test results, documentation, and certificates
  • Plans and drawings
  • Warranties and warranty information
  • Spare parts and supplier listings
  • Recommissioning plan
  • Sequence of operation
  • Software for systems should be installed and delivered

The provision of these documents is only one, of many, benefits of the commissioning process. Engaging in the commissioning process can minimize human error during construction and maintenance, identify problem areas, prolong a structures lifespan, and save money over the long-term.
