Emergency lighting
rules and regulations
The National Fire Protection Agency’s Life Safety Code (NFPA 101) specifies illumination
requirements (in most cases, 1 footcandle) for specific areas in buildings with different
occupancies that must be immediately available to facilitate egress in the event of an emer-
gency.TheserequirementsarediscussedinArticle7.8“IlluminationofMeansofEgress,”
Article7.9“EmergencyLighting,”andarticlesdealingwithspecificoccupancies.While
egress lighting and emergency lighting do have separate definitions, one set of lighting is
typically used to meet the requirements of both definitions.
NFPA70,theNational Electrical Code, defines what kinds of equipment may be used, and
the installation and maintenance practices that must be followed, to meet the illumina-
tion requirements of the Life Safety Code. The NEC discusses Emergency Systems in
Article700,anddefinesthemas“thosesystemslegallyrequiredandclassedasemer-
gency by municipal, state, federal, or other codes, or by any governmental agency having
jurisdiction. These systems are intended to automatically supply illumination, power, or
both, to designated areas and equipment in the event of failure of the normal supply or in
the event of accident to elements of a system intended to supply, distribute, and control
powerandilluminationessentialforsafetytohumanlife.”
TheNECalsodefinesLegallyRequiredStandbySystems(Article701)andOptional
StandbySystems(Article702),whichareoftenconfusedwithEmergencySystems,since
all are designed for use in the event of power failures, emergencies, natural disasters,
fire, etc. To clarify, Emergency Systems are those essential for safety to life, Legally
Required Standby Systems are extra systems required for specific types of buildings to
provide power to aid in fire fighting, rescue operations, control of health hazards, etc.,
and Optional Standby Systems are those intended to minimize the disruption to business
caused by power failures.
Underwriters Laboratories tests and approves the components of emergency systems to
be safe for a specific use. Two distinct listing categories apply to emergency lighting and
power control equipment: UL 1008 and UL 924. UL 1008, Automatic Transfer Switches for
Use in Emergency Systems, applies to the switching gear that transfers the power feed for
the emergency circuits from the normal source to the emergency source and back. UL 924,
Standard for Safety for Emergency Lighting and Power Equipment, applies to most of the
components downstream of the transfer switch. All components of an emergency circuit
must be appropriately designed and listed.

Emergency lighting is required in all public
facilities, but what is meant by the broad
term,“emergencylighting,”andwhich
regulations spell out the equipment and
performance that are required? Here’s a
brief overview.
Testing requirements:
Both NFPA 101 and the NEC require periodic functional testing of emergency lighting equipment.
54
Energy savings
Most facilities operate emergency lighting
24/7.Thisrepresentsasignificantenergy
usage that is not necessary. Now, with the
ELCU product line, building owners and man-
agers can control this emergency lighting
along with their normal lighting for increased
energy savings. And by operating the lighting
for fewer hours, they will also realize savings
from longer maintenance intervals for emer-
gency lamp replacement.
Emergency lighting typically consumes .15 to
.25 watts per square foot, or 12 to 21 percent
of an average building’s lighting load. Over
half of this power usage can be eliminated
by turning these lights off along with normal
lighting, after hours and on weekends.
Enhancing safety
With an ELCU, building operators can be
confident emergency lighting will come on
when it’s needed. In fact, they
can be assured of optimal
response because the ELCU
provides control at the branch
circuit level and it will force
emergency lighting on even if
normal power is interrupted
in only part of a building.
What’s
more, they
can turn
emergency
lighting on
when they
want to,
such as for
emergency
preparedness drills or trainings. By connect-
ing ELCU units with security, fire alarm or
other life safety systems, building managers
can automate the activation of emergency
lighting when it makes the most sense.
ELCU products are specifically UL listed and
labeled for use in emergency lighting cir-
cuitsandincludeLEDpowerindicatorlights
designed to insure personnel safety.
Flexibility
Sometimes building occupants want the ability
toturnalllighting–evenemergencylighting
–off,suchasforpresentationsorfilmsin
theaters, lecture halls, auditoriums, or in
museum galleries or classrooms. With an
ELCU, this is easy to do.

ELCU products monitor the status of the
normal power line and switch emergency
lights on only when they’re needed,
whether for normal usage or for an
emergency condition. An ELCU does this in
one of two ways, depending on whether it
is wired as a control device or as a bypass
device.
ELCU as a control device
An ELCU allows the status of normal
lightingcontroldevices–occupancy
sensors, lighting control panels, daylighting
controls–tocontrolemergencylightingin
tandem with normal lighting. It does this
by sensing the normal power line before
the control device and receiving a switching
signal from the line after the device.
When normal power is present to the
control device, and the device is feeding
power through to the normal lighting,
the ELCU switches the emergency
lights on. When normal power remains
uninterrupted, but the control device
turns the normal lighting off, the ELCU
follows suit and switches the emergency
lights off. However, when normal power to
the control device is lost for any reason,
the ELCU forces the emergency lights
onregardlessoftheon/offstatusofthe
control device.
This primary
application for ELCU
products allows
building owners and
designers to leverage
the energy saving
benefits of their control devices while still
complying with all the code requirements
for emergency lighting circuits.
Leverage the
energy saving
benefits
of control
devices
ELCU as a shunt or bypass device
In some cases it is desirable to have a
control device, often a line voltage dimmer,
on the emergency line in order to directly
control the emergency lighting. However,
that device must be bypassed in the
event of a power failure to ensure that
emergency lights come on, and come on at
full brightness. An ELCU provides a simple
solution for this kind of application too.
As a shunt, the ELCU senses the normal
power line. When power is present, it
allows the control device on the emergency
line to directly operate the emergency
lighting. In the event of a loss of normal
power, the ELCU completely bypasses the
control device, rerouting, or shunting, the
emergency line around it, immediately
forcing the emergency lighting on full in
compliance with code requirements.

The ELCU-100
mounts on a
DINrail.
An ELCU should be mounted in close
proximity to the normal control device that
it is sensing. By offering two ELCU models,
WattStopper makes this easy to do. The
ELCU-100mountsonaDINrail,eitherin
a lighting control panel or in an enclosure.
The ELCU-200 mounts to a junction box
and is plenum-rated.

options
The ELCU-200
mounts to a

In addition to normal operation, an ELCU
can be instructed to turn emergency light-
ing on by a remote device. This could be
a conveniently located remote test switch
or another building system such as a fire
alarm or security system. When the unit
hasbeenactivatedremotely,astatusLED
on the ELCU indicates this condition.

Open office
Large open space with multiple users
throughout the day.
Control needs:
Scheduled lighting control to ensure that lights
are on during periods of use and to switch lights
off overnight and during weekends and holidays
to meet energy code requirements.
Solution:
Overall switching is handled by a Lighting
Integrator panel. An ELCU-100 is installed on
the emergency circuit and connected to the
relay serving the area. The ELCU turns off the
emergency lights when the relay for the area is
turned off. If normal power to this relay is lost
for any reason, the emergency lights will turn on.
A remote test switch is installed in the
maintenance room for the floor for convenience.
Integrating ELCU
products into your
lighting designs
ELCUs are appropriate for emergency lighting,
night lighting and standby lighting applications
that include controls such as occupancy
sensors, lighting control panels, bi-level
controls, daylighting controls, dimmers and
switches.
An ELCU-100 is used for applications where
the normal control device is centrally located.
Examples include lobbies, corridors and some
open offices.
An ELCU-200 is used for applications where
the normal control device is located in the
space being controlled. Examples include
classrooms, conference rooms and open
offices with occupancy sensors.

WattStopper’s Emergency Lighting Control Unit
(ELCU) is a self-contained, emergency lighting
control device. The ELCU provides all required
functionality to allow any standard lighting control
device to control emergency lighting in conjunction
with normal lighting in any area within a building.
Mounting
Applications
The ELCU is designed to control lighting in areas
where emergency lighting fixtures are connected
on dedicated emergency lighting circuits that are
typically on 24 hours per day. The ELCU allows
normal control of emergency lighting for energy
savingsand/ortaskrelatedreasonswhilestrictly
adhering to National Electric Code requirements.
It is suitable for any application where enhanced
energy saving is desired.
Operation
The ELCU monitors a single circuit that provides
normal lighting to an area. As long as normal
power is present, the ELCU permits lighting
control devices (i.e., occupancy sensors, panels,
dimmers, or wall switches) to control the emer-
gency lighting fixtures as well as the general
lighting. If power is lost for any reason, including
the tripping of a single branch circuit breaker, the
ELCU will force the emergency fixtures for that
area on. The ELCU can be wired either as a control
device, so that emergency lighting follows the
control of normal lighting, or as a bypass device to
shunt emergency power around a control device
when normal power fails.
