Key takeaways
- An emergency lighting inspection checks that every unit lights the path out of the building when normal power fails, for as long as the code requires.
- NFPA 101 calls for a functional test of at least 30 seconds every month and a full 90 minute test once a year for battery units, with written records of both.
- Fire inspectors and insurers ask for the records, so the log matters as much as the test.
- Failed batteries, damaged heads, blocked units and dead circuits are the most common findings, and each has a simple fix.
An emergency lighting inspection is one of those tasks that is easy to put off, because the lights sit there working until the moment they are needed. When the power fails during a storm or a fire, those units are what let people find their way out. This guide is a practical annual checklist: what to test, what to record, and what usually goes wrong. It is written for building owners, property managers and facility staff across Texas.
For the testing rules themselves in more detail, our post on emergency lighting and exit sign testing goes through them. This post is the checklist you work from on the day.
Why the inspection matters
When normal power fails, a building can go dark in seconds. Corridors without windows, stairwells and interior rooms become hard to move through, and the people who know the building least, such as customers, guests and new employees, are the ones most likely to be caught out. Emergency lighting is what keeps the exit path visible for long enough to leave. A unit that has quietly failed gives no warning until the day it is needed, which is why a regular inspection is the only way to know the system works.
What the code asks for
NFPA 101, the Life Safety Code, sets the testing schedule for battery powered emergency lighting: a functional test of at least 30 seconds every month, and a full test of 90 minutes once a year, with written records of both. Fire marshals and insurers in Texas commonly ask to see those records. Systems fed from a generator instead of batteries have their own testing tied to the generator, which belongs in the same records.
The monthly test confirms the unit switches to battery and lights. The annual test confirms the battery can carry the light for the full time people may need to leave the building. A unit can pass every monthly test and still fail the annual one, which is why both exist.
Before you start
- A current list or floor plan of every emergency light and exit sign, with a number for each.
- Last year's records, so repeat failures stand out.
- A time when the building can tolerate the test, since a 90 minute test leaves units drained for hours afterward.
- A way to drop power to the units, either their test buttons, a remote test system or the circuits that feed them.
Plan the annual test for a time the building is lightly used, because the batteries need time to recharge afterward. Testing right before a busy evening leaves the building with weak units when it is full.
The annual inspection checklist
- Every unit on the list is present, mounted and undamaged.
- Each unit switches to battery when normal power is removed.
- Each unit stays lit for the full 90 minutes.
- The light falls where it should: on the exit path, stairs, doors and changes in level.
- Exit signs are lit, readable and point the right way after any remodel.
- No unit is blocked by new racking, signs, displays or added walls.
- Charging indicators show normal after the test and the units recharge.
- Remote heads, where used, light along with their battery unit.
- Every result is written down by unit number, with the date and who tested.
Who should run the test
Monthly functional tests are often done by facility staff, because they only involve pressing each unit's test button or using a remote test system and watching it light. The annual 90 minute test takes longer and turns up more failures, so many owners have it done by an electrician who can replace batteries and repair units on the same visit. Either way, the person testing needs the unit list, a way to record results, and permission to leave units drained for the hours they need to recharge.
Self testing units, which run their own monthly and annual tests and show the result on an indicator, reduce the labor but do not remove the need to check them. Someone still has to look at each indicator, record what it shows and act on any failure.
Generator fed emergency lighting
In buildings where emergency lighting is fed from a generator instead of batteries, the lights depend on the generator starting and the transfer switch moving the load. Testing those lights means testing that sequence. The generator's own testing and maintenance records belong beside the lighting records, because a failure in either one leaves the path dark.
What to record
The record is what an inspector reviews, so it should be complete enough that someone else could check the work. For each unit, note the number, the location, the test type, the result and the date. For each failure, note what was found and what was done about it, and the date it was fixed. Keep the monthly and annual records together for each year.
A record that only says the system passed, with no list of units, is hard to defend. A record that shows each unit and each repair is easy to defend.
Exit signs: what to look at
Exit signs are part of the same inspection. Each one should be lit on normal power and stay lit on battery or generator power for the full test. The face should be clean and readable from the path people will actually walk, and any arrow should still point toward the exit after walls, doors or shelving have moved. Signs hidden behind new displays, hanging banners or added ceiling features count as failures even when the sign itself works, because a sign nobody can see does not do its job. Note each sign on the unit list the same way as the lights, so a missing or covered sign shows up in the record.
Common failures and their fixes
- Batteries that fail the 90 minute test: replace the battery, or the whole unit when it is old or no longer made.
- Units that never switch to battery: often a failed charger board or a battery that is completely spent.
- Dead units on a circuit that was switched off or removed during a remodel: restore an unswitched feed as the code requires.
- Heads aimed at the ceiling or a wall after cleaning or painting: re-aim them at the exit path.
- Units blocked by new walls, racks or signs: relocate them or add units so the path stays lit.
- Exit signs pointing the wrong way after a layout change: replace or re-face them.
When a building has many old units, replacing them together with current LED units can cut down on the yearly failures. Our emergency lighting and exit signs page covers that work, and our electrical inspections page covers inspections more broadly.
When remodels change the requirement
A tenant build-out or a change of layout can change where emergency lighting is needed. New corridors, new rooms and moved exits all need to be covered. That review belongs in the build-out, not in next year's inspection. If a space is changing use entirely, the change of occupancy can bring its own requirements.
Emergency lighting tests can be built into a scheduled service plan, which our maintenance agreements cover, with a written record after each visit.
