New additions to the 2020 NEC and UL924 standard mean new possibilities and requirements for the design of a compliant emergency control system. In addition, new technologies such as Power Over Ethernet emergency systems must be designed in a compliant manner.


  1. To learn and understand changes in emergency lighting requirements in the 2020 NEC and UL standards, including their impact on Power over Ethernet (PoE) systems
  2. To understand the difference between Bypass and Transfer methods of control and where each is appropriate
  3. To understand what qualifies a luminaire as a Directly Controlled Emergency Luminaire and where they are used in an emergency lighting system
  4. To understand the landscape of available classes of Emergency Lighting Control devices and where each is appropriate
