RA-100 Remote Annunciator Installation

Wiring Distance Calculation Example:
Suppose a system is configured with the following SBUS modules:
2 - RA-1000 Fire Annunciators
1 - 5496 Intelligent Power Expander
1 - 5865 LED Fire Annunciator
1 - 5824 Parallel/Serial Interface
The total worst case current is calculated as follows:
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
• 2,362 feet maximum using 14 Gauge wire

Figure 4.11 illustrates SBUS, Class B configuration.
4.7 RA-100 Remote Annunciator Installation
The optional model RA-100 Remote Annunciator, is shown in Figure 4.12. The RA-100 can be surface or flush mounted. Up to 16 annunci-
ators can be added to the IFP-300 system in any combination.
