Regular testing of emergency lighting is essential to ensure its functionality when needed. The testing frequency depends on the type of system:
- Monthly: A brief functional test to ensure lights illuminate as expected.
- Quarterly: A more comprehensive test that includes a 30-minute functional test to ensure lights stay on for the required duration.
- Annually: A thorough test, often conducted by a professional, which includes a full 1 to 3-hour duration test to verify battery performance.
It’s essential to maintain detailed records of testing and any corrective actions taken.
