Adapting to the new requirements of UL 924 Emergency Lighting

In 2022, UL dramatically changed the requirements for detecting normal and emergency power for emergency lighting. This change has obsoleted many common methods of compliance, and at the same time has opened up new opportunities for simplified and lower cost compliance. Today there is significant confusion about the new standards, and many manufacturers products have not yet caught up to the new standards. This presentation explains the changes, how to comply with the new standard, and outline new methods to comply that can reduce the cost of emergency lighting compliance significantly.

Some background in emergency lighting will be helpful for this presentation.
