Wiring Configuration - Honeywell fire-lite alarms MRP-2002E Manual

Installation
Wiring Distance Calculation Example:
Suppose a system is configured with the following ANN-BUS modules:
• 2 ANN-80 Remote LCD 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
Using this value and referring to the Wiring Distance Table 2.1 on page 31, it can be found that
the available options are:

2.7.1.2 Wiring Configuration

Figure 2.15 illustrates the wiring between the FACP and ANN-BUS devices.
