EMERGENCY LIGHTING CONTROL RELAY (120 OR 277) 6A (ELCR-XXX-6A-234)
OVERVIEW
The ELCR-XXX-6A-234 is a single zone, silent emergency transfer control with universal
dimming capability. It can be used with 2 and 3-wire line voltage dimming systems, as well as
0–10V, DALI, and Lutron EcoSystem.
The ELCR allows emergency lighting to be dimmed with regular lighting during normal
times. In the event of a utility power interruption, the ELCR automatically transfer designated
emergency fixtures from the dimming control to the emergency power source and bring them
to full brightness, regardless of whether the dimming system is in operation or turned off.
FEATURES
• Slim, attractive flush mount profile allows easy access to manual test switch and LEDs
• Separate Utility & Emergency Power Indicator LEDs for regular and emergency power allow
verification of correct wiring connections
• Integral Test Switch provides convenient anytime testing
APPLICATIONS
• Voltage Surge Protection insures reliable performance under adverse conditions
• Auditoriums • Restaurants • Conference Rooms
• Theaters • Classrooms
SPECIFICATIONS
• Triple Interlock (electrical, mechanical, and time delay) maximizes safety and reliability of
the ELCR, by eliminating arcing and the potential for phase to phase shorts between separate
powers sources during transfer

• Emergency Power Supervision: An ELCR 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
be unnoticed, especially when mounted above the ceiling tile

EMERGENCY LIGHTING CONTROL RELAY (120 OR 277) 6A (ELCR-XXX-6A-234)
METHOD OF OPERATION
UNIVERSAL MOUNTING
ELCR 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 ELCR senses a loss or voltage drop and within 1.2 seconds
transfers the load to an available emergency source. When the normal utility power is restored, the
ELCR 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.

INSTALLATION
ELCR-XXX-6A-234 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 device in accordance with national/local codes and requirements.
Can be mounted surface, above suspended ceiling or flush
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 ELCR unit, cautioning that load is
supplied from 2 different power sources, regular and emergency.

When regular utility breaker is on, operate the 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.
C. All designated emergency light fixtures will now be full bright regardless
of whether the dimming system was turned on or off, and this is the
intended function of the ELCR (while conforming to UL 924 standards).

Do not turn dimmer system on but only press the test switch on
the ELCR. 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.
B. When main circuit breaker is turned off, UL1008 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.

Emergency Hot
When utility power on #1 and #2 is interrupted, emergency dimmed
ballasts 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 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 ELCR-XXX-6A-234.
The load connected to #5 and #7 is not controlled by the ELCR, therefore
ELCR rating is not applicable.
