Luminous Egress Path Marking Systems
UL 1994
1 Scope
1.1 These requirements cover floor proximity and other egress path marking and lighting systems that provide a visual delineation of the path of egress. These systems are also used to identify significant egress path features such as doors, door hardware, door frames, stairs, stair landings, stair banisters, obstacles, egress symbols, information placards, and similar elements of the egress path.
1.2 These systems are intended for installation and use as required by building and fire safety codes such as the Life Safety Code, NFPA 101; the Building Construction and Safety Code, NFPA 5000, and the International Building Code sponsored by the International Code Council.
1.3 These requirements cover photoluminescent egress path marking system materials such as sheeting and adhesive-backed laminates. They also cover paints, pigments or inks pre-applied to a substrate. They are intended for installation where the facility illumination is sufficient to activate the photoluminescent material.
1.4 These requirements do not address the mounting integrity of path markers intended to be secured by adhesive to a building element. The suitability of this form of mounting for any given application is outside the scope of this Standard.
1.5 Self-luminous systems include constructions as defined in 5.13.
1.6 Externally powered lighting systems include varying designs of electric lamps that may be intended for connection to any combination of normal power supply, emergency power supply, and battery backup.
1.7 These requirements do not cover egress signs and lighting to be used independent from a path marking system, such as EXIT signs or other legally required legends or graphical symbols that are within the scope of the Standard for Emergency Lighting and Power Equipment, UL 924.
1.8 These requirements do not address the text or graphical symbol content, or the configuration of path marker signs.
1.9 The term “product” as used in these requirements refers to egress path marking and lighting systems or any part thereof covered by these requirements unless specifically noted otherwise.
