Wiring Configurations - Honeywell SILENT KNIGHT RPS-2000 Installation And Operation Manual

Wiring Distance calculation example:
Suppose a system is configured with the following SBUS modules:
2 - Module RA-2000 Fire Annunciator
1 - RPS-1000 Intelligent Power Expander
1 - 5865 LED Fire Annunciator
1 - 5824 Serial/Parallel Interface Module
The total worst case current is calculated as follows:
RA-2000 Current Draw
RPS-1000 Current Draw
5865 Current Draw
5824 Current Draw
Total Worst Case Current Draw
Using this value, and referring to the Wiring Distance table, it can be found that the available
options are:
370 feet maximum using 22 Gauge wire
938 feet maximum using 18 Gauge wire
1493 feet maximum using 16 Gauge wire
2362 feet maximum using 14 Gauge wire
