What Is Integrated Systems Testing
Life Safety Systems Must Work Together
What Is IST — CAN/ULC S1001
Integrated Systems Testing, or IST, verifies that interconnected fire protection and life safety systems operate together as intended. This can include fire alarm, sprinkler and fire suppression systems, smoke control, emergency power, elevators, door releases, HVAC shutdowns, fire dampers, smoke dampers, and other systems with life safety functions.
Individual system testing confirms that each system works on its own. CAN/ULC S1001 Integrated Systems Testing confirms that the required interconnections between systems work together under simulated emergency conditions.
For example, a fire alarm activation may need to trigger mechanical shutdowns, smoke control sequences, door releases, elevator recall, emergency power responses, alarm notification, and other connected functions. IST verifies that these responses occur in the correct sequence, in the correct areas, and in accordance with the project design intent.
In BC, IST is required where fire protection and life safety systems, or systems with fire protection and life safety functions, are integrated with each other. It is commonly required on healthcare, institutional, and complex building projects before occupancy, and the results must be documented for review by the owner, consultants, contractors, and the authority having jurisdiction.
ITSL is ULC-certified for CAN/ULC S1001 Integrated Systems Testing. Our role is to coordinate the test process, review the required interconnections, and witness integrated system demonstrations. From there, we document results, identify deficiencies, and issue a clear IST report that supports project closeout and occupancy.
IST Services
What ITSL’s IST Scope Covers
From pre-test planning through final certification: a complete integrated systems testing engagement.
IST Plan Development
Development of a project-specific IST plan per CAN/ULC S1001 requirements. The plan identifies all systems to be tested, the test matrix, scenario sequences, pass/fail criteria, and documentation format, all reviewed and accepted by the authority having jurisdiction before testing begins.
Fire Alarm System Testing
Complete fire alarm system verification including initiating devices, notification appliances, control panel response, zone mapping, alarm transmission to monitoring station, and annunciator accuracy. Verified against the engineered fire alarm design and NFPA 72 requirements.
Smoke Control Verification
Testing of all HVAC smoke control sequences including fan shutdown, smoke damper operation, pressurization of stairwells and vestibules, and exhaust activation. Verified against the smoke control design sequences and the integrated response required by the fire alarm system.
Emergency Power & Lighting
Verification of emergency generator transfer timing, UPS system response, emergency lighting activation and illumination levels, exit sign visibility, and egress pathway lighting. Transfer time documented against BC Building Code and NFPA 110 requirements.
Door & Access Control Integration
Verification of magnetic door holder release on fire alarm, electrified door lock override for egress, access control system interlock with fire alarm, and stairwell re-entry lock function. Documented against life safety code requirements for the occupancy type.
Certified IST Report
A complete, signed CAN/ULC S1001 IST report documenting every test scenario, observed response, pass/fail result, and deficiency. Formatted for submission to the authority having jurisdiction, BC Health Authorities, and the building owner. Deficiency tracking through to resolution and re-test.
How We Work
The ITSL IST Process
A structured, five-stage process from project kick-off to certified report.
01
Project Review
Review of fire alarm drawings, smoke control sequences, mechanical and electrical designs, and life safety specifications. Identification of all systems requiring integrated testing.
02
IST Plan
Development and submission of the project-specific IST plan per CAN/ULC S1001. Coordination with the AHJ and design team for plan review and acceptance before testing begins.
03
Pre-Test Coordination
Scheduling of test dates with general contractor, mechanical/electrical trades, fire alarm contractor, and the AHJ. Confirmation that all systems are complete and ready for integrated testing.
04
Field Testing
Systematic execution of all IST scenarios per the accepted test plan. Real-time deficiency logging, contractor coordination for immediate corrections, and re-testing where required.
05
Certified Report
Issuance of the signed, certified CAN/ULC S1001 IST report with complete test records, deficiency resolutions, and a final pass declaration for AHJ submission and occupancy permit support.
Why Independence Matters
Integrated Life Safety Testing Requires Objective Review
Integrated Systems Testing is different from individual system testing. Fire alarm, sprinkler, emergency power, smoke control, elevator, door hardware, HVAC, and other life safety systems may each pass their own acceptance tests, but still fail to operate together as intended when a real emergency sequence is simulated.
That is why independent IST matters. The installing contractors confirm that their own systems are complete and ready for testing. The Integrated Testing Coordinator verifies the required interconnections between systems, coordinates the test process, documents the results, and identifies where the integrated response does not match the project requirements.
On complex projects, ITSL regularly identifies meaningful coordination issues during IST, even after individual systems have been tested and accepted within their own scope. These issues are often not visible until multiple systems are demonstrated together under the same scenario.
ITSL holds ULC certification for CAN/ULC S1001 Integrated Systems Testing. We do not design or install the systems being tested. Our role is to provide objective coordination, field witnessing, issue documentation, and a clear IST report that supports owner, consultant, and AHJ review, plus project closeout.
Because ITSL also performs commissioning and TAB on complex institutional and healthcare projects, our IST team brings a whole-building systems perspective to life safety testing. When fire alarm, smoke control, pressurization, emergency power, HVAC shutdowns, and other systems need to function together, that broader technical understanding is a practical advantage.

ULC-Certified Test Body — CAN/ULC S1001
ITSL holds ULC certification as a qualified test body for integrated systems testing — the national credential required by AHJs across BC.
Healthcare IST
IST for BC’s Most Demanding Life Safety Environments.
Healthcare facilities present the most complex IST scope of any building type in BC. Hospital life safety systems must protect patients who cannot self-evacuate, which means smoke control, pressurization, alarm notification, and staff alert systems must perform flawlessly in a highly zoned, operationally constrained environment.
ITSL has performed IST across more than ten full hospital tower projects in BC, including the Royal Inland Hospital Patient Care Tower (LEED Gold, 2023), Penticton Regional Hospital, and facilities for Interior Health, Vancouver Island Health, and Northern Health. Our team understands the clinical context of the spaces being tested: occupied hospital IST requires scheduling around patient care, sterile field protection, and infection control protocols, not just construction milestones.
BC Health Authority projects require IST by a certified independent test body. ITSL’s ULC certification, healthcare project history, and integrated TAB and commissioning capability make it the natural single-source choice for Interior BC hospital projects.

IST vs. Commissioning
Related Scopes — Distinct Purposes
IST and commissioning are frequently confused on complex projects. Understanding the difference ensures the right scope is specified at the right stage.
Integrated Systems Testing
Verify life safety systems respond together
What it does
Tests the integrated response of all life safety systems — fire alarm, smoke control, suppression, emergency power, egress — to confirm they operate as a coordinated network per the design intent and code requirements.
When it happens
Near project completion when all systems are installed and individually tested. IST typically occurs 2–4 weeks before the target occupancy date to allow time for deficiency resolution.
Authority
Governed by CAN/ULC S1001. Required by the BC Building Code on specified occupancies and by BC Health Authorities on all healthcare facilities. AHJ reviews and accepts the IST report.
Commissioning
Verify mechanical and building systems perform as designed
What it does
Independently verifies that mechanical, electrical, and controls systems are installed and operating to the Owner’s Project Requirements. TAB, controls verification, and functional performance testing are all part of commissioning.
When it happens
Ideally begins at design phase and continues through post-occupancy. The commissioning process runs in parallel with construction and concludes after the building has been in operation long enough to verify seasonal performance.
Authority
Governed by CSA Z320, Z8001 (healthcare), and LEED requirements. Required by BC Health Authorities and increasingly specified on all institutional and LEED projects by engineers of record.
💡
When ITSL performs IST, commissioning, and TAB on the same project, smoke control sequences verified during commissioning feed directly into IST scenario planning. TAB results confirm the airflows that smoke control depends on. There is one issue log, one point of accountability, and no risk of contradictions between scopes. For complex institutional and healthcare projects, this integrated engagement model is the standard ITSL approach.
Why Inland Technical
What Sets ITSL’s IST Practice Apart
ULC-Certified for CAN/ULC S1001
ITSL is a ULC-certified test body for CAN/ULC S1001 Integrated Systems Testing. This gives owners, consultants, contractors, and AHJs confidence that the IST process is coordinated and documented by a qualified independent provider, not self-declared by the project team.
Independent Life Safety Verification
ITSL does not design or install the systems being tested. Our role is to coordinate the IST process, witness integrated system demonstrations, and document results. We identify deficiencies and provide a clear report for review. That independence matters because fire alarm, sprinkler, emergency power, smoke control, HVAC, elevators, doors, and other systems must be verified together, not only within each contractor’s individual scope.
Integrated IST, Commissioning, and TAB Capability
ITSL can support IST, commissioning, and TAB under one coordinated team. This is especially valuable on healthcare, institutional, and complex building projects where mechanical systems, controls, pressurization, smoke control, emergency power, and life safety interfaces overlap. One team with whole-building systems knowledge helps reduce gaps between scopes and improves coordination during testing and closeout.
Healthcare and Institutional IST Experience
ITSL has extensive experience supporting life safety testing on healthcare, institutional, and complex building projects across BC and beyond. Our team understands phased occupancy, active facility constraints, infection control coordination, documentation expectations, and the level of planning required when testing life safety systems in clinical and public environments.
Local Presence With BC-Wide Reach
With offices in Kamloops and Kelowna, ITSL is positioned to support IST coordination, pre-test reviews, partial testing, deficiency follow-up, and final demonstrations throughout the project. Our team supports projects across BC and beyond while maintaining the practical field presence needed for complex life safety testing.
Issues Found Before Occupancy
IST often identifies coordination issues even after individual systems have passed their own acceptance testing. A fire alarm device may activate correctly, but the connected HVAC shutdown, smoke control response, door release, elevator recall, or emergency power sequence may not perform as intended. ITSL’s process is designed to find these integration issues before occupancy, when they can still be corrected by the project team.
Clear Documentation for Closeout
ITSL’s IST reports are structured to support review by owners, consultants, contractors, AHJs, health authorities, and other project stakeholders. Reports document the tested scenarios, participating systems, observed results, deficiencies, retesting, and final status so the project team has a clear record of how the integrated life safety systems performed.
Falcon Engineering has worked with Inland Technical Services on both tendered and design build projects with great success. ITS brings strong technical expertise with regards to the balancing and commissioning services required to bring a project to a successful conclusion.

Common Questions
Integrated Systems Testing Questions, Answered
When is CAN/ULC S1001 IST required in BC?
CAN/ULC S1001 Integrated Systems Testing is required where fire protection and life safety systems, or systems with fire protection and life safety functions, are integrated with each other. This applies to new construction, and can also apply to renovations, additions, tenant improvements, or system modifications where life safety system interconnections are added or changed.
IST can include fire alarm, sprinklers, emergency power, smoke control, elevators, door releases, HVAC shutdowns, fire dampers, smoke dampers, pressurization systems, emergency lighting, and other connected life safety functions.
How often is IST required?
IST is completed before occupancy for new construction. After the initial test, integrated testing is required one year later and then every five years after that for buildings where the ongoing testing requirement applies.
Additional testing may also be required when renovations, equipment replacements, control changes, or life safety system modifications affect the original system integrations.
Who can perform Integrated Systems Testing?
IST must be planned, coordinated, witnessed, and documented by a qualified Integrated Testing Coordinator or qualified test provider with knowledge of the systems being tested. The required qualifications depend on building complexity, project specifications, AHJ requirements, and whether the testing is for new construction, an existing building, or a major alteration.
ITSL is ULC-certified for CAN/ULC S1001 Integrated Systems Testing and provides qualified coordination, field witnessing, deficiency tracking, retesting, and final reporting.
Can the fire alarm contractor perform IST?
The fire alarm contractor plays an important role in IST, but they are not a substitute for an independent Integrated Testing Coordinator on projects that require third-party verification. Contractors confirm that their own systems are installed, tested, and ready. The IST provider verifies how all connected systems work together under the approved test scenarios.
How far in advance should IST be scheduled?
IST should be planned early, ideally during design, tender, or commissioning planning. The IST plan depends on the project documents, system interconnections, sequences of operation, contractor participation, AHJ expectations, and system readiness.
For final testing, ITSL recommends allowing several weeks for planning, coordination, system readiness review, test scheduling, deficiency correction, and retesting. Healthcare, institutional, and occupied buildings usually require more lead time due to access, infection control, clinical operations, shutdown planning, and phased occupancy.
What happens when IST identifies a deficiency?
If an integrated system response does not match the accepted test plan or design intent, ITSL documents the issue, identifies the affected systems, and assigns the item for correction where applicable. Once corrective work is complete, the affected scenario is retested.
Deficiencies, corrective actions, retesting, and final status are documented in the IST report so the owner, consultants, contractors, and AHJ have a clear record of what was tested and resolved.
Can ITSL perform IST in an occupied building?
Yes. ITSL can perform IST in occupied healthcare, institutional, and commercial buildings. This work requires careful planning with facility staff, contractors, consultants, and building operations.
Occupied building IST may require staged testing, temporary measures, occupant notification, infection control coordination, after-hours work, and detailed shutdown planning to reduce disruption while still verifying the required life safety functions.
Does ITSL perform IST outside Kamloops and Kelowna?
Yes. Kamloops and Kelowna are ITSL’s operational bases, but our team supports IST projects across BC and beyond. Project location, scope, schedule, and resource availability are reviewed so the work can be properly planned, competitively delivered, and coordinated with commissioning or TAB where applicable.
What does the owner receive at the end of IST?
The owner receives a ULC-certified IST report documenting the test plan, systems tested, scenarios demonstrated, observed results, deficiencies, retesting, and final status. This provides a clear record that the required life safety system interconnections were tested and documented for project closeout, occupancy, and future reference.
