What Is Integrated Systems Testing
Life Safety Is a System. Testing It That Way Is a Requirement.
Standard Definition — CAN/ULC S1001
Integrated systems testing is the process of verifying that the interconnected life safety systems within a building — fire alarm, fire suppression, smoke control, emergency lighting, security, HVAC shutdown, and elevators — function together as a coordinated, code-compliant network when subjected to a simulated emergency scenario.
Individual system testing — fire alarm acceptance testing, sprinkler system commissioning, emergency lighting verification — confirms that each system works on its own. What CAN/ULC S1001 IST confirms is that all these systems work together the way the building code and design intent require when an actual emergency is triggered.
Consider a fire event in a hospital. When the fire alarm activates, it must simultaneously trigger HVAC smoke control sequences, lock down magnetic door holders, release pressurized stairwells, recall elevators, notify monitoring stations, and switch emergency lighting. Every one of those actions must happen in the correct sequence, within specified time delays, in every zone of the building. IST is the process that verifies this integrated response actually works — not just in theory, but in the actual installed building.
In BC, CAN/ULC S1001 IST is required by the BC Building Code on a growing range of occupancies, and is mandated by BC Health Authorities on all healthcare facilities. It must be performed by a qualified, independent test body — not the installing contractors — and the results must be documented in a signed IST report that satisfies the authority having jurisdiction (AHJ) before occupancy is granted.
ITSL is a UL-certified body for CAN/ULC S1001, which means we meet the national qualification standard for performing and certifying integrated systems tests. Our IST team — led by Logan Wriglesworth, B.A.Sc Mechanical Engineering — brings both the technical depth and the documentation rigour that BC building authorities, healthcare authorities, and insurance underwriters require.
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 — 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 documentation to 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
The Contractors Who Install the Systems Cannot Certify Them.
CAN/ULC S1001 requires that integrated systems testing be performed by a qualified, independent test body — specifically, one that is not the manufacturer, installer, or contractor responsible for any of the systems being tested. This independence is not administrative. It is the entire point of the standard.
When the fire alarm contractor tests their own system, they are verifying their own work against their own interpretation of the design intent. When ITSL performs IST, we are an independent third party with no financial interest in the outcome of any individual system — only in accurate, defensible documentation of how the building’s life safety systems actually behave together.
For healthcare facilities, this independence is a BC Health Authority requirement. For any building requiring a CAN/ULC S1001 IST report for occupancy, the authority having jurisdiction will confirm the test body’s credentials. ITSL’s ULC certification satisfies that requirement in every BC jurisdiction.
ITSL’s IST scope is delivered by the same team that performs commissioning and TAB on complex institutional projects — which means we bring a whole-building systems perspective to life safety testing that a specialist electrical contractor cannot. When smoke control, pressurization, HVAC, and fire alarm all need to function as one integrated system, having a single test body that understands all of them is a material project advantage.

UL-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 us 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 issues 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
UL-Certified Test Body — Accepted Across BC
ITSL’s ULC certification as a CAN/ULC S1001 test body is the credential that BC authorities having jurisdiction require. Our certification is not self-declared — it is independently verified by UL and held to the national standard. Every IST report ITSL issues carries that certification.
Integrated IST, Commissioning, and TAB — One Firm
ITSL is one of very few BC firms qualified to deliver commissioning, TAB, and CAN/ULC S1001 IST under a single contract. The efficiency, accountability, and coordination advantages of this model are most visible on complex healthcare and institutional projects where all three scopes overlap.
Healthcare IST Experience No Other Interior BC Firm Matches
With IST delivered across more than ten full hospital towers, ITSL’s healthcare life safety testing expertise is unmatched among Interior BC firms. Our team has navigated occupied hospital testing protocols, phased occupancy IST, and BC Health Authority documentation requirements on projects ranging from 50,000 to over 400,000 square feet.
Field-Based in Interior BC — Consistently On-Site
ITSL’s Kamloops and Kelowna offices mean our IST technicians are available throughout the project — not mobilizing from Vancouver for test day. Pre-test coordination, partial system testing, and deficiency follow-up are all handled by the same team that is already on site for commissioning and TAB.
IST Reports Accepted by AHJs and Health Authorities Without Revision
ITSL’s CAN/ULC S1001 reports are structured to meet the documentation requirements of BC fire departments, building inspectors, BC Health Authorities, and insurance underwriters. Our clients don’t spend their occupancy process chasing report revisions.
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 — Answered
When is CAN/ULC S1001 IST required in BC?
IST is required by the BC Building Code on buildings with complex fire protection systems, interconnected life safety systems, or high-risk occupancies. BC Health Authorities mandate it on all healthcare facilities. Many institutional clients and engineers of record specify it on educational, civic, and commercial buildings as well. If you’re unsure whether your project requires IST, contact ITSL and we’ll confirm based on occupancy classification and system scope.
Can the fire alarm contractor perform IST on their own installation?
No. CAN/ULC S1001 requires IST to be performed by an independent test body that is not the manufacturer, installer, or contractor responsible for any of the systems being tested. The fire alarm contractor performing IST on their own installation does not satisfy the standard, and the resulting report will not be accepted by the authority having jurisdiction.
How far in advance should IST be scheduled?
ITSL recommends engaging us for IST at the same time as commissioning — typically at the design or tender phase. The IST plan must be developed and accepted by the AHJ before testing begins, which requires lead time. For test scheduling, we recommend a minimum of 4–6 weeks before the target IST date. On healthcare projects, 8–12 weeks is more realistic given the complexity of scheduling in a live facility environment.
What happens when IST identifies a deficiency?
Any system response that does not match the accepted IST plan is logged as a deficiency. ITSL documents the specific failure, the affected systems, and the required corrective action. The relevant contractor is notified immediately during the field testing session where possible. Once corrections are made, ITSL performs a targeted re-test of the affected scenario. All deficiencies and their resolutions are documented in the final certified IST report.
Can ITSL perform IST on an occupied building?
Yes. ITSL regularly performs IST in occupied healthcare facilities — including active hospital wards — where testing must be scheduled around patient care, infection control, and clinical operations. This requires detailed pre-test planning with facilities management, staged testing sequences that minimize disruption, and close coordination with building operations staff. Our team has significant experience managing the operational constraints of healthcare IST in live environments.
Does ITSL perform IST outside the BC Interior?
Yes. While our Kamloops and Kelowna offices are our operational base, ITSL delivers IST across BC on healthcare and institutional projects. Projects on Vancouver Island, the Lower Mainland, and Northern BC are all within our regular service footprint for IST engagements, particularly where we are also performing commissioning and TAB on the same project.
