General Information
In the past, all emergency lights were left on 24 hours a day
to meet safety codes. Now you can specify & install a UL924
Listed Emergency Power Control CEPC-2-D, which converts up
to 20A of normal light fixtures to approved emergency lights.
During normal operation, the CEPC-2-D dimms and switches
designated emergency lights with the same switch or control as
your normal lights. During a utility power interruption, the CEPC-
2-D turns designated emergency lights on to full brightness.
regardless of dimmer output position.
Emergency Power Source and Method
of Operation
The emergency luminaire power is derived from a 24 hour central
emergency power source. The local utility power company
normally supplies the power through a UL 1008 Transfer Switch
or equal, but during a utility power failure, the transfer switch
automatically switches to the emergency power source. The
room switch turns ON and OFF both regular and emergency
luminaires simultaneously. This is accomplished by having the
room switch leg power activate the Cooper Lighting Solutions
Emergency Power Control, CEPC-2-D. Wire input #1 or #2 and
neutral are connected internally to a sensing circuit. During a
power interruption on the sensing input, this circuit causes
contact X to drop into a N.C. position and turns ON the
emergency load(s). Review Wiring Diagram.
Patented Automatic Diagnostic - When the room switch is
turned off, CEPC-2-D tests itself for 2.5 seconds, testing that
an emergency power source is available and that the CEPC-2-D,
lighting is functioning correctly. This feature eliminates the need

for manual monthly testing and is approved for this purpose.
This allows installation in any location because its test switch
does not need to be accessible. This feature can be disabled in
the field by cutting the blue jumper.
Fire Alarm / Remote Test Switch - Some applications demand
that emergency lighting be activated upon fire alarm, security
alarm, or remote test switch activation. The CEPC-2-D is
equipped with a low voltage override input (red jumper).
Universal Mounting - Unique enclosure permits flush, fixture,
plenum or panel mounting.
Installation

local code requirements, a qualified electrician should review &
