DIP Switch and Jumper Selections for Main Board and Adder Modules
6.2 MR-2300-A Input Class-A Converter Adder Module
Figure 10 MR-2300-A Input Class-A Converter Adder Module
There are no jumpers or cables to set on this module, just wiring from the converter (wires are
fixed here) to the Main Fire Alarm Board.
Initiating circuits must be wired from the MR-2300-A module to the Main Fire Alarm board. For
example, Initiating circuit 1 positive (red) and negative (black) wires are connected to the
positive and negative terminals (respectively) of Initiating circuit 1 on the Main Fire Alarm
Board. From the MR-2300-A converter Initiating circuits are wired out to the devices from the
positive and negative terminals marked DET OUT and the circuit return wires are brought back
to the converter module to positive and negative terminals marked DET RET.
To convert all 12 initiating circuits of the Fire Alarm Panel, two of these MR-2300-A Input Class
A Converter Adder Modules are required.

JW4 Leave closed (on).
JW5 Leave open (off).
Note: This module has built in Active End-of-Line resistors and so the fire alarm system
should be configured to enable Active End-of-Line. See section 11 on page 53.
