Report Forms & Documentation Updates
What Are CAN/ULC-S536:2019 and CAN/ULC-S537:2019
Mandatory Use of Standardized Report Forms
The days of custom or abridged checklists are over! Starting on January 1st, 2026, all annual and monthly inspections must be recorded using the official ULC-S536:2019 report forms.
- Each inspection report must list every tested device, outcome, and deficiency.
- Technician attendance logs are also required – outlining names, dates, and inspection durations.
- Owner sign-off on completed deficiencies is mandatory to demonstrate compliance.
Separating Deficiencies and Recommendations
Under the new CAN/ULC-S536:2019 standard, every inspection report must separate deficiencies from recommendations. “Deficiencies” are items that do not meet the standard and must be corrected, while “recommendations” are best-practice suggestions for optional system improvements.
Strengthened Documentation Requirements
Under the new standards, building owners and property managers must maintain the following documentation on-site and up-to-date:
- Annual inspection reports (using official ULC-S536:2019 forms)
- Monthly inspection logs
- Verification certificates for new or altered systems (as required under ULC-S537:2019)
- Drawings and device lists
- Battery test results with recorded load data
- Deficiency lists and proof of corrective actions
- Descriptions and action sequence for operating fire alarms
- Fire Safety Plan reflecting new inspection protocols
Additional Testing Requirements
Enhanced Battery Testing Requirements
The traditional capacity testing method for testing standby batteries is no longer compliant. Instead, a new functional load test (sometimes referred to as the “Silent Accelerated Test”) is required.
During the test, each battery must be tested under load to confirm it can power the system for its rated capacity, with all readings recorded in the official inspection report. This process may take longer, but it provides far more reliable performance data and helps to prevent hidden failures during an emergency.
Expanded Isolator and Device Testing
The CAN/ULC-S536:2019 standard also expands testing requirements for isolators and fire separation zones. This is done to confirm that each isolator device properly isolates affected zones and ensures their reliability – even under extreme conditions like water damage, mechanical failure, or partial system destruction.
