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 ELECTRICAL • • • • • • cULus UL924 Listed 120V/277V Sensing Input 120V/277V (20AMP) Load Rating 20A (120V/277V) Ballast Load Rating 1800W (120V) / 1500W (277V) Incandescent Load Voltage Surge Protection DIMENSIONS MECHANICAL • • • • • • • 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.

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. 4.7in 4-11/16” 2” 2.0in 2” 2.0in 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.

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). 4 2 Regular Neutral 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. SWITCH UTILITY POWER Emergency Utility Power Turn on 24/7 emergency circuit breaker. At this time, emergency circuit power is still derived from utility power.

Do NOT cut X1 or X2 Jumper for 2 Wire Loads 10 5 INITIAL TESTING AFTER INSTALLING 3. 9 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.
