rules and regulations
Emergency lighting is required in all public
regulations spell out the equipment and
facilities, but what is meant by the broad
performance that are required? Here’s a
term, “emergency lighting,” and which
brief overview.
NFPA
101
NEC
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 emergency. 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 illumination 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 emergency 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.
Testing requirements:
Both NFPA 101 and the NEC require periodic functional testing of emergency lighting equipment.
UL
4
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.

and safety
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
6
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.

designers to leverage
the energy saving
benefits of their control devices while still
complying with all the code requirements
for emergency lighting circuits.
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.

normal power. A separate green LED indicates

Description
Mounting
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.
The ELCU is equipped with an integral DIN rail
mounting groove and retaining clip mechanism.
It can be installed on the DIN rail track provided
within a WattStopper enclosure (i.e., LS-E8,
LS-E12), or in a WattStopper lighting control panel.
Operation
12
Integrated push-to-test
button
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 emergency 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.
Features
• Eliminates energy waste caused by “always ON”
emergency lighting
• Integral push-to-test button activates emergency mode for a true test condition
• Connects to remote test switch or other input to
activate emergency ON from a remote location
• Operates as a control device or as a shunt
• Senses local single circuit power failure

• Zero cross switching technology for reliability
and increased product life
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.

WattStopper’s ELCU-200 Emergency Lighting
Control Unit is a self-contained device that allows
any standard lighting control device to control
emergency lighting in conjunction with normal
lighting in any area within a building.

Applications
The ELCU-200 monitors a single circuit that
provides normal lighting to an area. As long as
normal power is present, the ELCU-200 permits
lighting control devices (e.g., occupancy sensors,
panels, dimmers, or wall switches) to control the
emergency 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-200 will force on the emergency fixtures for
that area. The ELCU-200 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 (e.g., a dimmer) when normal power fails.
The ELCU-200 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-200 allows normal control of emergency
lighting for energy savings and/or task related
