Emergency Light Testing

For many commercial buildings, emergency lighting is typically required in exit routes and other parts of the means of egress, and it must activate within 10 seconds of a power outage.

Testing and maintenance

Common testing requirements are a 30-second functional test every month and a 90-minute full-duration test once a year, with records kept for inspection. Many jurisdictions also require UL 924-listed equipment for emergency lighting fixtures and power units
