|Explanation of terms||
Installers and designers frequently refer to “Egress Lights” and “Emergency Lights” as if the two terms are interchangeable. They are not.
“Egress Lights” are lighting fixtures connected to the normal power supply system and are to function at all times the area is occupied.“Emergency Lights” are (typically) battery type emergency unit equipment that provide no illumination until failure of the egress light circuit. These fixtures serve as “backup” for the egress lights. Together they form an Emergency Lighting System.
