General Specifications
Emergency Power Supervision
Exclusive LVS Feature
An EPC-D-F uses internal supervision circuits to prevent
emergency luminaires from illuminating during normal times if
Emergency Hot or Neutral conductors have been interrupted.
This gives warning that a problem exists with emergency
supply, which would otherwise be unnoticed, especially when
controls are mounted above ceiling tile.

Weight: 16 oz.
Ambient Temp. Rating: 32 F - 140 F
UL 94V-0 Flame Rating on all EPC
prodcuts. Safe for installation above
suspended ceiling.
Triple Safety & Reliability
EPC-D-F consists of 2 contactors, C-1, and C-2.
C-1 is energzied during normal times, and is deenergized when
regular power is interrupted.
C-2 is energized when regular power is interrupted, and is
deenergized when regular power is restored.

EPC-D-F is designed to be installed as a wiring
device in the area the dimmable lights are, or in a
central location. A qualified electrician should review
and understand installation instructions before
installing or servicing the EPC-D-F in accordance
with national/local codes and requirements.
CAUTION: This unit shall be wired with a conductor
that has an insulation rating of at least 75°C.
The unit shall not be installed in j-boxes
with through branch wiring .
Check voltage and current requirements. Verify and
lock out circuit breakers on both normal power and
24 hour night light/emergency generator circuit.
Install a self-adhesive 2" x 3" caution label outside of
ballast channel in each fixture/load controlled by an
EPC-D-F unit, cautioning that load is supplied from 2
different power sources, regular and emergency.

This light xture is powered by 2

regular power branch circuit
breaker before servicing this
light xture.
Review wiring diagram and connect wires, one wire
at a time, in accordance with the numerical identification. In order to provide a safe light level, when regular power is interrupted, it is recommended that a
minimum of two 4' fluorescent tubes providing
approximately 5000 lumen are controlled by a 24
hour emergency circuit and are spaced no farther
than 24' in any direction from each other in a normal
9' white ceiling environment.

Model EPC-D-F single zone silent operating control
is a versatile, cost effective unit, specifically
designed for dimmable lights in public places where
critical light levels of at least 1 foot candle must be
maintained during a loss of normal utility power.
The EPC-D-F senses a loss or voltage drop and
within 1.5 seconds transfers the load to an available
emergency source. When the normal utility power is
restored, the EPC-D-F senses this and will transfer
the load back to the normal utility power within 1.5
seconds. Momentary incorporated test switch simulates normal power failure and can be performed
anytime. Any interruption of normal utility power will
automatically transfer designated emergency lights
to the full bright condition regardless of whether the
dimming system is in operation or turned off.

Initial testing after installing EPC-D-F
17 AMP Max Emergency Load
Normally Dimmed & Full Bright
During Power Failure
1. Turn on regular power circuit breaker and if all
wire connections are correct, utility power green
LED will be illuminated.
2. Turn on 24/7 emergency circuit breaker. At this
time emergency circuit power is still derived from
utility power, and if all wire connections are correct,
emergency power red LED will be illuminated.
3. Do not turn dimmer system on but only press test
switch on EPC-D-F. Designated emergency light
fixtures should then come on full bright. These
fixtures would also come on full bright if regular
utility power circuit breaker is turned off. This is
another testing method to use.
4. When regular utility breaker is on, operate
dimmer control and observe if all fixtures light up,
including designated emergency fixtures and if
dimmer system lights respond normally when
adjusted from low to high level.

Final Testing
A. Coordinate with occupants a convenient time
that the main circuit breaker can be turned off, and
test all emergency lights.
B. When main circuit breaker is turned off UL 1008
transfer switch or equivalent will automatically
change position and emergency circuits will now be
powered from either a generator, inverter, or UPS
emergency source system.
C. All designated emergency light fixtures will now
be full bright regardless of whether the dimmming
system was turned on or off, and this is the
intended function of the LVS Model EPC-D-F and
conforms to UL 924 standards.

When utility power on #1 and
#2 is interrupted, emergency
dimmed ballast will then be
automatically switched, after a
time delay, to emergency
power. After #1 and #2 power
is interrupted, low voltage
control signal (violet wire) is
automatically interrupted and
causes
the
designated
emergency dimmed ballast
loads to automatically go to full
brightness. This sequence of
events will occur whether the
system is turned on or off. The
emergency load connected to
#8 and #10 cannot exceed
rating of EPC-D-F. The load
connected to #5 and #7 is not
controlled by EPC-D-F and
therefore EPC-D-F rating is not
applicable.
