Abstract
Devices, systems, and methods for automatically managing emergency lighting testing are generally described herein. The automated emergency lighting testing may include scheduling emergency lighting events, verifying that emergency lighting power sources and fixtures are sufficient to maintain requisite light intensity for a requisite amount of time, and calculating life expectancy for emergency power sources and lighting fixtures to predict when components should be replaced to avoid failure. The disclosure reduces the amount of time and manual intervention required for the tests by using, among other things, a system of lighting control drivers, sensors, and processors that monitor, assess, and control the lighting system including emergency lighting components and power.
