Application
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 Shunt Relay RRU-UNV, which converts up to 20Aof
normal light fixtures to approved emergency lights. During normal operation, the RRU-UNV switches
designated emergency lights on and off. During a utility power interruption, the RRU-UNV turns desig-
nated emergency lights on, regardless of switch position.
Intended for use with switching and line voltage dimming controls.
What is the difference between an
Emergeny Shunt Relay (RRU) and an Emergency Power Control (EPC)?
An emergency shunt relay requires a dedicated switch/dimmer to control the emergency
lights. In other words, the switch/dimmer must be wired on the emergency power circuit.
An emergency power control allows the same switch/dimmer to control both normal and
emergency lights. In other words, the switch/dimmer can be wired on the normal power
circuit.
Universal Mounting - Unique enclosure permits flush, fixture, plenum or panel mounting.

Installation
In order to install the RRU in accordance with national/local code requirements, a qualified electrician
should review & understand the installation instructions. Check voltage & current requirements.
Verify & lock out circuit breakers on both regular (utility) power & 24 hour emergency generator or
inverter circuit. Install a self-adhesive 2" x 3" caution label in each fixture or load controlled by an RRU
cautioning that the load is supplied from 2 different power sources, normal & emergency. Review
wiring diagram & connect wires, one at a time, in accordance with the numeric identification. In order
to provide a safe light level, when regular power is interrupted, it is recommended that a minimum of
appproximately 5000 lumen are controlled by a 24 hour emergency circuit & are spaced no farther
than 24' in any direction from each other in a normal 9' white ceiling environment.
Initial Testing and Troubleshooting
In a new installation, where hundreds of devices may be used, each having as many as 14 wires to
be correctly connected, it is important that a fast, convenient method is used to check connections.
In order to test that the wires are connected correctly, without any inconvenience to occupants, do
not turn off regular (utility) power off until you have checked each device as follows:
1) Check that regular branch circuit breaker is connected & utility power is available. Green LED
should be lit. If green LED is not lit, check connections & continuity to branch circuit breaker.
2) Check that emergency branch circuit breaker is connected & emergency power is available.
3) Normal Operation Test: Turn switch or other control device to the “ON” position. Emergency
lights should turn on. Turn room switch or control to the “OFF” position. Emergency lights should
turn off.
4) Emergency Operation Test: Press and hold test button, emergency lights should illuminate at full
brightness until test button is released.
Maintenance
No maintenance is required to keep the RRU functional. However, regular testing should be
performed when the lamps or ballasts have been replaced or when remodeling has taken place.

Wiring Diagram #1: A dedicated switch or line voltage dimmer controls emergency lighting in a
space. Upon loss of normal power, the emergency lighting comes on at full brightness regardless of switch
or dimmer position. NOTE: RRU-UNV is not for use with 0-10V DIMMER. Use RRU-X-UNV or EPC-2-D.
