The AD1C13 is an Alpha-numeric annunciator that uses a display panel with a matrix of 64 x 8 LEDs. It is designed to operate with the range of NurseCall central equipment to display call messages. The LEDs are two colours (red and green) and can display messages in Red, Yellow and Green.
The display is clearly visible from 20 metres on axis under normal interior lighting levels. Text can be displayed in red for high priority, yellow for medium priority and green for low priority.
