Emergency lighting remote monitoring and control system
First Claim
1. A wireless remotely controlled emergency lighting system comprising:
- (a) an emergency lighting unit having, (1) a ballast transceiver, and (2) a ballast controller in communication with said ballast transceiver;
said controller receiving command data from said ballast transceiver and sending status data to said ballast transceiver; and
(b) a central control unit having, (1) a central transceiver in communication with said ballast transceiver, and (2) a central controller in communication with said central transceiver;
said central controller receiving said status data from said central transceiver and sending said command data to said central transceiver.

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.

15. An emergency lighting system comprising:
-
(a) an emergency lighting unit having, (1) a lamp;
(2) a backup power supply in communication with said lamp;
(3) a switch coupled between said power supply and said lamp; and
(4) a ballast controller coupled to said backup power supply, said ballast controller generating status data representative of the results of self tests of said emergency lighting unit; and
(b) a central controller in communication with said ballast controller, said central controller having a memory, storing said status data in said memory, generating a prediction of a failure as a function of said status data, and communicating said prediction to a user interface;
wherein said user interface is in communication with said central controller, said user interface communicating said status data to an operator. - View Dependent Claims (16, 17, 18)
