Illuminated exit signs and emergency lighting commonly need to be tested on a regular schedule, typically a brief functional test each month and a longer full-duration test once a year, as required by life-safety codes so the systems are confirmed to work when needed. Because these are life-safety devices that must operate during a power loss, regular testing is essential and is a building owner’s responsibility. The exact requirements depend on the applicable code and jurisdiction. Understanding the typical schedule helps businesses stay compliant and safe.

Here is how often exit signs need to be tested.

Testing requirements for exit signs and emergency lighting are set by life-safety codes and can vary by jurisdiction and equipment, so always confirm the specific requirements with your local authority and a licensed electrician.

A regular testing schedule is required

Life-safety codes generally require illuminated exit signs and emergency lighting to be tested on a regular schedule to confirm they function. Because these systems must work during a power loss, which is unpredictable, periodic testing is how you verify they will perform when an actual emergency occurs. Testing is not optional, it is a required part of maintaining these life-safety systems.

The common monthly and annual tests

The typical testing requirement has two parts:

• A brief monthly functional test, commonly a short test (on the order of 30 seconds) confirming the sign or light illuminates on backup power
• An annual full-duration test, commonly a longer test (on the order of 90 minutes) confirming the backup power lasts the required duration

The monthly test checks that the system activates, while the annual test confirms it can run for the full required time on backup power. These two tests together are the common schedule under life-safety codes.

Why both tests matter

Both tests serve a purpose. The brief monthly test catches units that have failed outright, a dead battery or a failed fixture, so they can be fixed promptly. The annual full-duration test verifies that the backup power actually lasts long enough, since a battery might activate but not hold for the full required time. Together they confirm the systems both work and will last through an emergency, which a single check could not fully verify.

It depends on the code and equipment

While the monthly and annual tests are the common pattern, the exact requirements depend on the applicable life-safety code, the jurisdiction, and the equipment. Some systems have self-testing features that automate the checks, and specific requirements can vary. The reliable approach is to confirm the testing requirements for your building with your local authority and a licensed electrician, and to keep records of the testing as typically required.

Keeping records and fixing failures

Along with testing, businesses are generally expected to keep records of the tests and to repair any units that fail. Documentation demonstrates compliance, and prompt repair ensures the life-safety systems remain functional. A licensed electrician can perform the testing, maintain the systems, document the results, and repair or replace failed units, keeping the building compliant and its occupants protected.

Illuminated exit signs and emergency lighting commonly need a brief functional test each month and a longer full-duration test once a year, as required by life-safety codes, to confirm they work and that the backup power lasts. The monthly test catches failures, and the annual test verifies duration. Exact requirements depend on the code, jurisdiction, and equipment, and records should be kept. A licensed electrician can handle the testing and maintenance.
