Emergency Lighting Requirements.
F-14.2.1 Provide emergency lighting in accordance with NFPA 101, Section 5 -9.
F-14.2.2 Emergency lighting is required only for designated stairs, aisles, corridors,
ramps, escalators, and passageways leading to an exit. Interior rooms and windowless
rooms usually do not require emergency lighting unless they qualify as a windowless
structure or an underground structure as defined in NFPA 101, Section 32 -7.
Mechanical rooms, telephone equipment rooms, toilets, and similar utility spaces
usually do not require emergency lighting. Although an elevator is not considered a
component in the required means of egress, all elevators must provide lighting in
accordance with ANSI A17.1, Safety Code for Elevators and Escalators, or ANSI A17.3,
Safety Code for Existing Elevators and Escalators, as applicable.
F-14.2.3 Where emergency lighting is required, arrange the system so that the failure
of any individual lighting element, such as the burning out of a light bulb, cannot leave
any space in total darkness.
F-14.2.4 The following are acceptable emergency lighting systems.
Fixtures connected to a permanently installed facility electrical generator. Any
generator used for this purpose must be installed, maintained, and tested in
accordance with NFPA 110, Emergency and Standby Power Systems.
Fixtures with internal battery packs that are part of a drop-in light system. The
system must be installed, maintained, and tested in accordance with NFPA 111,
Stored Electrical Energy Emergency and Standby Power Systems.
Fixtures with remote battery packs. The system must be installed, maintained, and
tested in accordance with NFPA 111, Stored Electrical Energy Emergency and
Standby Power Systems.
Normal lighting system designs. Emergency lighting fixtures can be either separate
from or designed as integral parts of the normal lighting system; some luminaires are
provided with normal and emergency lighting within the same enclosure.
F-14.2.5 The following are prohibited emergency lighting systems.
New construction--do not use fixtures with wall-mounted battery packs.
Existing construction--remove existing fixtures equipped with wall -mounted battery
packs wherever such fixtures are not required by NFPA 101. Do not remove fixtures
for the sole purpose of eliminating wall -mounted battery packs if the emergency
lighting is required by NFPA 101 and the fixtures meet minimum NFPA 101
