4.0 System Overview
The block diagram in Figure 4 shows the major components of a typical Beacon
installation. The parts of the system are the LED Beacon and Controller. The LED
Beacon is made up of one LED module, which lights when current passes through it. The
LED Module contains its own internal power supply. The Beacon is designed for use
with an external controller. This external controller provides the properly timed flashing
