Wiring Distance Calculation Example:
Suppose a system is configured with the following ANN-BUS modules:
• 3 ANN-80 Remote Fire Annunciators
• 1 ANN-S/PG Serial/Parallel Printer Interface Module
The total worst case current is calculated as follows:
ANN-80 Current Draw
ANN-S/PG Current Draw
Total Worst Case Current Draw
Using this value and referring to the Wiring Distance Table 1.1 on page 25, it can be
found that the available options are:
926 feet maximum using 22 Gauge wire
2,344 feet maximum using 18 Gauge wire
3,731 feet maximum using 16 Gauge wire
5,906 feet maximum using 14 Gauge wire
