SBUS Wiring Distance Example SBUS Wiring Distance 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 1 - 5824 Serial / Parallel Interface Module
The total worst case current is calculated as follows:
RA-2000 Current Draw
RPS-1000 Current Draw = 1 x .010 amps
5865 Current Draw
5824 Current Draw
Total Worst Case Current Draw
= 2 x .120 amps
= 1 x .200 amps
= 1 x .040 amps
= .240 amps
= .010 amps
= .200 amps
= .040 amps
= .490 amps
