WIRING DIAGRAMS for UL 924 - SWITCH BYPASS Applications

The GTD20A uses an internal relay contact to control the AC power feeding the lighting load. When the generator (or
central inverter) supplies AC power to the lighting fixture, the GTD20A bypasses the local switching means or dimmer.
This ensures the lighting load will be energized at full lumen output during generator (or central inverter) operation
regardless of switch position or dim setting.
No routine maintenance is required to keep the GTD20A functional. However, it should be checked periodically to
ensure that it is working properly. Note: Make sure to disconnect both the normal and emergency panel circuit breakers
before servicing.
! REFER ANY SERVICING INDICATED BY THESE CHECKS TO QUALIFIED PERSONNEL !
STEP #3 FOLLOW-UP & QUICK TEST OF THE INSTALLATION
> Mark each designated emergency lighting fixture with the warning labels provided (20 labels are provided
with each unit).
> Apply AC power to all circuits. The green "Normal Power Present" and the red "Emergency Power Available"
LED's should be illuminated.
> Perform a quick test as described on the unit label to check for proper operation. When the test
button is depressed, the green "Normal Power Present" LED should extinguish and the controlled
lighting load should illuminate regardless of the local switch position provided emergency power is
available (check red LED).
> During a quick test using a GTD20A with a dimming system, the lighting load should illuminate at
full lumen levels when the test switch is depressed regardless of the lumen level during normal operation.
> The entire generator (or central inverter) system, including all designated lighting loads, should be
exercised to ensure proper operation (e.g., power up the generator, throw the main automatic transfer
switch to the generator position, and check the lighting loads to verify they are operating properly from
the generator/central inverter supply).
