Guide Information for Electrical Equipment for Use in Ordinary Locations



This category covers electrical emergency lighting and power equipment for use in accordance with ANSI/NFPA 101, "Life Safety Code," Article 700 of ANSI/NFPA 70, "National Electrical Code" (NEC), and the "International Building Code" (IBC).

Emergency power equipment is intended to supply sufficient electrical energy for emergency luminaire operation, or to distribute and manage the electrical energy for emergency luminaires from a remote emergency supply source. Emergency power equipment with batteries has a test switch and visible or audible indicators to report the readiness of the emergency supply.

Emergency lighting equipment is intended to illuminate the means of egress, or means of egress signage, under both normal and emergency conditions.

Equipment may contain both emergency power and lighting capability, or may provide only one of the two functions.


This category covers emergency luminaires, exit signs, unit equipment, inverters, central-station battery systems, load-control relays, and related accessories that directly facilitate or supplement the function of these devices.

This category also includes emergency battery packs intended for factory or field installation inside or outside the luminaire housing, as noted in the installation instructions. These packs have been investigated by UL to determine that, when installed in accordance with the manufacturer's instructions, they do not adversely affect the operation of the installed luminaire and are capable of supplying sufficient power to effectively illuminate the means of egress for the required period of time. Electrical ratings, lamp compatibility, and wiring diagrams are marked on the packs and/or identified in the instructions provided.

When an emergency LED driver is included in a certified LED luminaire retrofit kit (see Light-emitting-diode Luminaire Retrofit Kits (IFAR)), the resulting converted luminaire is also eligible to serve as part of a facility's emergency lighting system in accordance with the Codes referenced above.


All products have been investigated for use in dry locations only unless marked as suitable for damp or wet locations. Products marked as suitable for indoor damp or wet locations have not been investigated for UV exposure. All products have been investigated for use in ambient temperatures of 20 - 30°C (68 - 86°F) unless otherwise marked with an extended-use temperature range.

Emergency power equipment with batteries provides 90 minutes (or more, if so marked) of rated operating power for emergency lighting equipment (integral or remote) sufficient to meet the illuminance performance requirements of ANSI/NFPA 101 and the IBC, when installed as part of a facility's emergency lighting system.

Exit signs have been investigated for visibility from 100 ft unless marked with a maximum viewing distance of 50 or 75 ft.

Exit signs investigated for installation near floor level have been subjected to an impact test and are marked "Suitable for Floor Proximity Installation."

Emergency LED drivers marked as having Class 2 outputs are eligible for field connection in accordance with Article 725 of the NEC.

Exit signs intended for connection to a single source of power only are covered under Exit Fixtures (FWBO). Exit signs with no connection to a source of electrical power are covered under Exit Signs, Self-luminous and Photoluminescent (FWBX).

Emergency battery packs intended for use with LED luminaires may also be covered under Emergency Light-emitting-diode Drivers (FTBV).

Equipment intended to provide light or power when normal (utility) power is not available, but that has not been investigated for compliance with the applicable power or illumination performance requirements of ANSI/NFPA 101 or the IBC, is covered under Lighting and Power Equipment, Auxiliary (OUST).

Kits intended to convert exit signs from one type of internal light source to another are covered under Exit Sign Conversion Kits (FWCF) or Exit Sign Retrofit Kits (GGET).

Emergency lighting and power equipment intended for use on marine vessels is covered under Luminaires, Emergency Lighting, Marine (IGTC).

Equipment intended to transfer utilization equipment from the normal (utility) supply to an emergency supply, and back again, including branch circuit emergency lighting transfer switches (BCELTS), is covered under Automatic Transfer Switches for use in Emergency Systems (WPWR).
