MR-2300-A Input Class-A Converter Adder Module

Figure 4: 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.
