Abstract
An emergency lighting monitoring and control system controls and monitors the emergency lights in a building. A central control unit automatically schedules self tests for each of the emergency lights and stores the results of the tests in memory. The self tests include tests of the backup power source and the lamp. Some failures are predicted prior to actual failure. Failures are diagnosed and repairs are suggested. Light output is automatically monitored and adjusted. The central control unit generates a report of the self tests and notifies an operator of failures. An operator views test reports, controls the emergency lights, and schedules tests. The system automatically detects newly installed emergency lighting units.
