Emergency and Exit Lighting Testing and Compliance

If it fails: the first hour

What the site contact should do before the technician arrives.

Identify the specific fixture or exit sign that failed and its location on the egress path
Post temporary battery-powered lighting or signage if the fixture cannot be repaired immediately
Contact a licensed electrician or life safety contractor for same-day repair
Document the failure and temporary measure taken for the facility's compliance record

What fails

Battery unable to hold the full 90-minute test durationNFPA 101 requires emergency lighting to function for a minimum of 90 minutes on battery power during the annual test; aging batteries often fail well before that mark even though the unit appears to work during a quick check.

Exit sign lamps or LED modules burned outIndividual lamps or LED boards inside an illuminated exit sign fail over time, leaving part or all of the sign dark, most often noticed only during a scheduled test rather than daily use.

Missing monthly functional test documentationNFPA 101 requires a brief functional test monthly in addition to the annual 90-minute test; buildings that only do the annual test are missing a required, and often overlooked, code requirement.

Egress lighting not covering the full pathEmergency lighting fixtures placed too far apart leave dark gaps along a corridor or stairwell, failing the code requirement for continuous illumination along the egress path.

Self-test units reporting false pass statusSelf-testing emergency lighting units can develop a fault that causes them to report a passing status without actually completing a full battery discharge test, giving a false sense of compliance.

Battery corrosion and connection failureBattery terminals corrode over time inside emergency light housings, breaking the connection and causing the unit to fail even though the battery itself may still hold a charge.

Photocell or charging circuit failureA failed charging circuit lets the battery slowly discharge without recharging, so a unit that passed its last test can fail the next one even without any battery age issue.

What a service call includes

Performing the required 30-second monthly functional test and documenting the result
Conducting the annual 90-minute full discharge test on battery-powered units
Testing illuminated and non-illuminated exit signs for visibility and lamp or LED function
Replacing failed batteries, lamps, or LED modules found during testing
Checking spacing and coverage of egress path lighting against code-required foot-candle levels
Inspecting self-testing units for fault codes and confirming actual test completion, not just a passing indicator light
Providing a written, dated test log for the facility's life safety compliance file

Preventive checklist

The items a maintenance program should carry for this system. Build a combined checklist across systems with the checklist builder.

Quarterly

Perform the required monthly functional test and log the result
Visually check exit signs for burned-out lamps or LED segments

Annual

Conduct the full 90-minute battery discharge test required by NFPA 101
Replace batteries approaching the end of their rated service life, typically every 3 to 5 years
Review the full year's test log for gaps in monthly documentation

What it costs

item	typical range	what moves it
Emergency light and exit sign inspection, per unit	$15 to $40	Lower end applies to bulk testing across many units in one visit.
Battery replacement, per unit	$30 to $100	Sealed lead-acid batteries are common and generally at the lower end; specialty batteries cost more.
LED exit sign replacement	$50 to $150 installed	Replacing an older incandescent sign with an LED unit reduces long-term energy and bulb replacement cost.
Annual compliance testing program, small building	$300 to $1,200 per year	Covers scheduled monthly and annual testing across all emergency lighting and exit signs in the facility.
Egress lighting gap correction, added fixture	$200 to $600 per fixture	Includes fixture, wiring to the emergency circuit, and installation labor.

National ranges. Local labor, access, after-hours timing and materials move them. Multi-site programs usually price below one-off calls.

When this is an emergency

A completely dark egress path or a non-functioning exit sign discovered outside a scheduled test counts as an emergency because it is a direct life safety gap that needs same-day correction.

How to choose a provider

Confirm the provider tests to NFPA 101 requirements, including both monthly and annual test intervals
Ask how self-testing units are verified, since a passing indicator light does not always mean a full test completed
Request a sample test log to see the level of documentation provided after each visit
Ask about battery replacement policy, including whether aging batteries are flagged proactively before failure
Confirm the provider can perform same-day emergency repairs when a unit fails outside the testing schedule

Questions

How often does emergency lighting need to be tested by code?

NFPA 101 requires a functional test of at least 30 seconds monthly and a full 90-minute discharge test annually for battery-powered emergency lighting and exit signs.

What happens if emergency lighting fails its 90-minute test?

The unit needs repair or battery replacement and should be retested to confirm it meets the full duration; a failed unit found during testing is a code deficiency that requires correction, not just documentation.

Are exit signs required to be illuminated at all times?

Yes, exit signs must be continuously illuminated, either by normal power or by internally illuminated or photoluminescent means, and remain visible during a power outage.

Who is responsible for emergency lighting compliance in a commercial building?

The building owner or the tenant, depending on the lease terms, is generally responsible for maintaining and testing emergency lighting to meet local fire code and NFPA 101 requirements.
