Basic Operation
Each pair of LED indicators on the annunciator consists of two of the following three colors: green, amber and red. The color choices allow for custom configuration of Status, Warning and Shutdown indicators. For example, a pair of red and amber LED indicators may be configured for engine oil pressure. If a low engine oil pressure warning is read over the data link, the annunciator will flash the amber LED and the audible horn will sound. If the low engine oil pressure shutdown is read over the data link, the annunciator will flash the "Red" LED and the audible horn will sound.In order to acknowledge the shutdown and alarm conditions or to silence the horn, press the alarm acknowledge button.In order to test the LED indicators, or in order to test the horn, press the lamp test button and hold the lamp test button.Table 2 lists the available color combinations for the 17 pairs of lights that are on the annunciator.
