OVERVIEW
SAFETY INSTRUCTIONS
In the past, all emergency lights were left on 24 hours a day to meet safety codes. The Emergency Shunt Relay converts up to 20A of
normal light fixtures to approved emergency lights. During normal operation, the AD-RRU-X-UNV dims designated emergency lights
with the same control as normal lights. During a utility power interruption, the AD-RRU-X-UNV turns designated emergency lights on, at
ful lbrightness, regardless of dimmer position. 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.
READ AND FOLLOW ALL SAFETY INSTRUCTIONS! When using electrical equipment, basic safety precautions should always be
followed, including the following:
1. This product can be used with LED, ballast, tungsten, and general use loads.
2. Make sure all connections are in accordance with the National Electrical Code and local regulations.
3. To reduce the risk of electric shock, disconnect both normal and emergency power supplies before servicing.
4. This product is intended to be used to control indoor and outdoor located loads.
5. An unswitched AC power source is required (120-240VAC/277VAC).
6. Do not install near gas or electric heaters.
7. Do not attempt to service a sealed Emergency Power Control. When malfunctioning, return to Legrand
8. The use of accessory equipment is not recommended by the manufacturer and may cause unsafe condition.
9. Do not use this product for other than its intended use.
10. Servicing should be performed by qualified service personnel.
11. Equipment should be mounted in locations and at heights where it will not readily be subjected to tampering by unauthorized
personnel.

FIRE ALARM / REMOTE TEST SWITCH
Some applications demand that emergency lighting be activated upon fire alarm, security alarm, or remote test switch activation. The
AD-RRU-X-UNV is equipped with a low-voltage override input (red jumper).

INSTALLATION
INITIAL TESTING, TROUBLESHOOTING, AND MAINTENANCE
Unique enclosure permits flush, fixture, plenum or panel mounting.
In order to install the RRU in accordance with national/local code requirements, a qualified electrician should review and understand
the installation instructions. Check voltage and current requirements. Verify and lock out circuit breakers on both regular (utility) power
and 24 hour emergency generator or inverter circuit. Install a self-adhesive 2” x 3” caution label in each fixture or load controlled by an
AD-RRU-X-UNV cautioning that the load is supplied from 2 different power sources, normal and emergency. Review wiring diagram and
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 and are
spaced no farther than 24’ in any direction from each other in a normal 9’ white ceiling environment.
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.
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 and utility power is available. Green LED should be lit. If green LED is not lit,
check connections and continuity to branch circuit breaker.
2. Check that emergency branch circuit breaker is connected and emergency power is available.
3. Normal Operation Test: Turn dimmer or other control device to the “ON” position. Emergency lights should turn on. Reduce
dimmer to ~50%, emergency lights should dim to ~50%. 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.
5. Maintenance: No maintenance is required to keep the RRU functional. However, regular testing should be performed when the
lamps or ballasts have been replace or when remodeling has taken place.

LVOS-0-10-PWM STATION DIAGRAM
The station supports two Override modes, ON and OFF. When either switch is closed ALL loads are ON or OFF depending on which
override loop is closed. However, the ON override takes precedence over the OFF override if both switches are closed. Exmaple below
is all loads ON.
