Inspection

Inspection, under CAN/ULC-S536, is the visual examination of a fire alarm system already in service to confirm it appears capable of operating as intended. It is a distinct activity from testing, which is the operational confirmation that a device or function actually works, and both are distinct from verification, which is the one-time acceptance process for new or altered work under CAN/ULC-S537. In Ontario the duty comes from Fire Code Article 6.3.2.2, and Division C, Article 1.2.1.2 requires the person doing it to have completed a program or course acceptable to the Fire Marshal. The trade uses inspection, testing and verification interchangeably; the standards do not.

What it is, and what it is not

Inspection is looking. You are confirming by eye that a device is present, undamaged, unobstructed, correctly labelled, mounted where the drawings say and in an environment it is listed for. Testing is making it work and watching the panel respond. The two words are used as one word on most sites, but CAN/ULC-S536 treats them as separate activities with separate procedures, and an inspection report that records no test results is not an inspection and test report.

Neither is verification. Verification is a one-time acceptance process for new or modified work under CAN/ULC-S537, driven by construction. Inspection is a recurring duty on a system in service. Full side by side in verification vs annual inspection.

Which standard and which code provision

The standard is CAN/ULC-S536. In Ontario, Fire Code Article 6.3.2.2.(1) requires a fire alarm system, with or without voice communication capability, to be inspected and tested in conformance with S536. Fire Code Table 1.2.1.A fixes the edition at S536-2019, which took effect for Ontario on 1 January 2026.

Note the section heading if you are searching the regulation. Section 6.3 is not called Fire Alarm Systems. It is called Alarm and Voice Communication Systems for Life Safety.

Who is permitted to do it

Unlike verification, this one is named. Fire Code Division C, Article 1.2.1.1 applies to any person performing annual tests or annual inspections required under 6.3.2.2, and Article 1.2.1.2.(1) requires that person to have successfully completed a program or course acceptable to the Fire Marshal, and to produce a certificate attesting to it on request from the owner or the Chief Fire Official.

The regulation names no provider. Not CFAA, not Certi-Fire. Which programs are accepted is administrative and can change without any amendment to the regulation, so "CFAA registration is legally required" is not a statement O. Reg. 213/07 supports. See who can legally work on fire alarms in Ontario.

How often

Here is the precision point. Article 6.3.2.2 states no frequency at all. Read it. There is no interval in it. It delegates the whole question to S536, and the frequencies live in the standard, which is paywalled. Daily, monthly, annual and multi-year intervals all exist there.

The word annual enters the Fire Code elsewhere: Article 6.3.2.1 refers to the annual tests or inspections required by the Subsection, and Division C Article 1.2.1.1 regulates who may perform them. So the Code assumes an annual cycle and regulates the person, but it does not itself set the number.

What documentation it produces

Four things, and the last three get missed. A completed S536 inspection and test report on the form the standard mandates. A description of the system kept current and in the building at an approved location, under 6.3.2.2.(3). A per-device record stating whether each device, component and circuit is in proper working order, under 6.3.2.2.(4). And on a monitored system, a record of whether the monitoring station actually received the test signals, under 6.3.2.2.(5). That last one is a record of receipt, not of transmission.

Retention is two years, and at least the most recent record plus the one before it, under Article 1.1.2.2.(1). Contrast the verification report, which is kept for the life of the system. See also attendance log.

What goes wrong

Partial reports. Since the 2019 editions the report forms sit in the body of the standard rather than an appendix, which makes the format mandatory. Calgary Fire Marshal Bulletin 2025-001 states that all sections of S536 and S537 must be completed, that partial reports will not be accepted, and that tests or inspections may not be reworded or revised in order or format. Sections that do not apply are marked N/A rather than deleted.

Writing "6.3.2.2 requires annual inspection" in a report or a quote. It requires inspection in conformance with S536. The interval is the standard's.
