How often emergency lighting is tested in Alberta
Emergency lighting testing in Alberta is a monthly check and a yearly endurance test. The National Fire Code 2023 Alberta Edition (NFC(AE) 2023) sets them out in Division B, 6.5.1.6 to 6.5.1.8, and the rules are short enough for one table. New to the code framework? Start with how Alberta's fire code fits together.
| Equipment | What gets done | How often |
|---|---|---|
| Self-contained emergency lighting units | Inspect the unit (pilot light on, terminals clean, clamps tight, battery surface clean and dry) and confirm the lights come on when normal power fails | Monthly |
| The same units | Run the full design duration on a simulated power failure, then check charger voltage, current and recovery against the manufacturer's specs | Every 12 months |
| Other emergency lights | Inspection | At least every 12 months |
| Exit signs | Inspection | At least every 12 months |
| Battery-backed exit signs | Check they stay lit on power failure, and run a full-duration check | Monthly, then every 12 months |
| Emergency generators | Follow CSA C282-15, with liquid fuel drained and refilled | Fuel at least every 12 months |
CSA C282 gets cited for these tests more often than it should. C282 covers emergency electrical power supply, meaning generators, and the code applies it to generators and their records (6.5.1.1 and 6.5.1.4). The battery-unit schedule comes from 6.5.1.6, and the units themselves are built to CSA C22.2 No. 141.
The code names no certificate for the monthly or yearly test, so trained building staff can do them. But the yearly one is the awkward job. It drains the battery, and until the unit recharges it can't cover a real outage, so on a big site we'd stagger units across the day rather than run them all at once.
How long emergency lights have to run
Thirty minutes in most buildings. NBC(AE) 2023, Article 3.2.7.4, sets the duration by building: 30 minutes for most occupancies, 1 hour for care, treatment and detention buildings (Group B) that aren't high buildings, along with a couple of other categories the article names, and 2 hours in high buildings.
The 90 minutes you'll see in search results is the US figure, from NFPA 101 and the International Building Code. It isn't the number in Alberta's building code.
The yearly test runs the unit for its design duration, so the test length follows the building. A unit designed for 30 minutes gets 30. A system designed for 2 hours gets 2. If a light goes dark at minute 22 of a 30-minute design, it failed. Read the design duration off the drawings or the unit label and write it at the top of the test log.
How bright emergency lighting has to be
The average has to be at least 10 lx at floor or tread level, and no point can fall below 1 lx. That's NBC(AE) 2023, Article 3.2.7.3. It applies in exits and the principal routes to them, public corridors, corridors serving classrooms, underground walkways, assembly and daycare areas, commercial kitchen food preparation areas and public washrooms serving more than one person, among other places the article lists.
The 2023 Alberta edition adds two locations: doors held by electromagnetic locks, and universal washrooms, shower rooms and accessible change spaces. The first ties into your fire alarm system, which is what releases those locks.
Ten lux is about 0.93 footcandles. The "1 footcandle average, 0.1 minimum" rule of thumb is US practice, so if a layout came from a US template, check it in lux.
Levels drift when the building changes. A new row of racking, a partition or a relocated door can leave a route darker than the drawing says, so raise it with the electrical designer when walls move.
Battery units, remote heads and central systems
Self-contained units, with the battery, charger and lamp heads in one housing, are the workhorse in most commercial buildings. Remote-head systems put the battery in a cabinet and the lamps elsewhere, which suits parkades and large open rooms. Central systems run a battery bank or inverter to emergency circuits across the whole building. Generator-backed lighting sits under the CSA C282 regime instead.
Each has a trade-off. Picture a building with 150 battery units: 150 pilot lights to check, 150 batteries with different birthdays. A central system has far fewer batteries, but one fault in it can darken a whole floor.
The monthly and yearly articles are written around unit equipment. For remote and central systems, keep the manufacturer's maintenance manual in the electrical room. Where the fire code has no specific rule for a device, it must still be maintained to operate as designed (Division B, 2.1.3.6).
Exit signs
Required exit signs use the green ISO 7010 running-figure pictogram, with arrows where direction matters. NBC(AE) 2023, Article 3.4.5.1, wants one over or next to every exit door when the building is more than 2 storeys, has an occupant load over 150, or the area uses a fire escape. It also wants directional signs where no exit is visible from a public corridor or from an open floor area with more than 150 occupants. Internally lit signs are built to CSA C22.2 No. 141. Photoluminescent and self-luminous signs, and externally lit ones, follow CAN/ULC-S572. Sign circuits serve emergency equipment only and connect to emergency power.
Old red EXIT signs are still everywhere. Whether an existing one has to come down is your AHJ's call, and where that turns on a code question it's fire code consulting work. A new required sign should be the pictogram type.
Inspection is every 12 months, with the monthly and yearly checks added on battery-backed signs. A photoluminescent sign has no battery to fail, but it can still fail: stock stacked in front of it, or a room never lit well enough to charge it, will do the job.
Records and Edmonton's LIV portal
Keep the test records at the building. NFC(AE) 2023, Division C, 2.2.1.2, requires them at the premises for the AHJ, with none destroyed within five years of being prepared. Generator records follow CSA C282 (Division B, 6.5.1.4), and when an emergency power system is shut down, supervisory staff have to be told (6.5.1.2).
A one-page log per floor does the job: unit number or location, date, pass or fail, who did it. For the yearly test, add the run time reached and the charger check.
If a contractor does the yearly test, the report falls under EFRS's Life Safety Inspection Vault, where the City lists emergency lights among the covered systems. Deficient reports must go in, and EFRS recommends uploading all of them. The inspections page explains LIV, including the disagreement over which reports are required. Our note on how LIV reporting works goes into more detail.
Why emergency lights fail their tests
- Batteries at the end of their life. A unit can pass the monthly blink and still die in the yearly test, because only the yearly test proves the battery can hold. Manufacturers publish replacement intervals that vary by battery type, so follow the label on yours.
- A dead charger, a tripped breaker or a circuit someone switched off. The pilot light goes dark.
- Corroded terminals, loose clamps or a wet battery case in damp spaces, which is why the monthly inspection looks at them.
- Racking, partitions or lamp heads knocked out of aim, which change the lit route.
- Exit signs blocked by banners, stock or ceiling tiles, or wired to a switched circuit.
- Cold. Batteries lose capacity in unheated parkades and loading docks, so check the unit's rated temperature range.
If nobody has tested the lights in years
So start with a count. Number every unit and sign, note the dark pilot lights, function-test them all, replace what fails, then run the full-duration test in stages. The unit count and the failure rate drive the price, so we'd rather count than guess. Send the address and your best estimate of the number of units through the contact page and we'll set up a first visit.
Frequently asked questions
How often do emergency lights need to be tested in Alberta?
Monthly and yearly. Self-contained units are inspected and function-tested every month and run for their full design duration every 12 months, followed by a charger check (NFC(AE) 2023, 6.5.1.6). Other emergency lights and exit signs are inspected at least every 12 months, and battery-backed exit signs get a monthly check plus a yearly full-duration check.
How long do emergency lights have to stay on in Alberta?
Thirty minutes in most buildings, 1 hour in care, treatment and detention buildings that aren't high buildings, and 2 hours in high buildings (NBC(AE) 2023, 3.2.7.4). The yearly test runs each unit for that full time. The 90-minute figure comes from US codes.
How bright do emergency lights have to be?
At least 10 lx on average at floor or tread level, and no less than 1 lx at any point (NBC(AE) 2023, 3.2.7.3). That's roughly 0.93 footcandles. The layout is the designer's job, and it needs revisiting whenever walls or racking move.
Are red EXIT signs still allowed?
New required signs use the green ISO 7010 pictogram (NBC(AE) 2023, 3.4.5.1). Existing red signs are a question for your AHJ. If one fails or a renovation replaces it, fit the pictogram type.
Who is allowed to test emergency lighting?
The code names no certificate for the monthly or yearly test, so trained staff or a contractor can do it. Generators are different: the weekly and monthly checks need someone trained by the generator manufacturer or a service provider, and other generator work needs manufacturer training (Division C, 2.2.4.7). Keep dated records either way.
