Product Information Guide

INITIAL SYSTEM TEST

Power is applied to the control unit through a line cord plugged into a standard 110 V AC
outlet. A lighted green LED, visible in the upper left corner of the control unit, serves as the
POWER ON indicator. The control unit software checks all its common hardware
immediately after the powerup. At this point, test the CO lines and stations at the controller.
