Wiring Configuration - Honeywell Fire-Lite Alarms MS-9050UD Manual

Product Description
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
• 1 ANN-I/O LED Driver Module
The total worst case current is calculated as follows:
ANN-80 Current Draw
ANN-S/PG Current Draw
ANN-I/O Current Draw
Total Worst Case Current Draw
Using this value and referring to the Wiring Distance Table 1.1 on page 21, it can be found that
the available options are:
