Model 5600 Installation and Operation Manual
Note: The following formulas were used to generate the wire distance chart:
Maximum Resistance (Ohms) =
Maximum Wire Length (Feet) =
(6000 feet maximum)
where: Rpu = Ohms per 1000 feet for various wire gauges (see table below)
Table 4-2:
Wiring Distance calculation example:
Suppose a system is configured with the following SBUS modules:
1 - Module 5635 Fire Annunciator
The total worst case current is calculated as follows:
5635 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:
1852 feet maximum using 22 Gauge wire
4688 feet maximum using 18 Gauge wire
6000 feet maximum using 16 Gauge wire
6000 feet maximum using 14 Gauge wire
