Installation
In order to install the LUT 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 LUT
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. Red
LED should be lit. If red LED is not lit, check connections & continuity to branch circuit breaker.
3) Normal Operation Test: Turn dimmer or other control device to the “ON” position. Normal &
emergency lights should turn on. Reduce dimmer to ~50%, normal and emergency lights should dim
together. Turn room switch or control to the “OFF” position. Normal lights should turn off immediate-
ly. If blue loop is connected, emergency lights should stay on for at least 2.5 seconds. If blue
jumper is cut and capped, emergency lights should turn off immediately.
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 LUT functional. However, regular testing should be
performed when the lamps or ballasts have been replaced or when remodeling has taken place.
