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

of the
MR-2306-R6 Relay Adder Module
connects here.
Otherwise not used.
JW2
Remove this jumper if an
MR-2306-R6 Relay Adder Module
is used.
JW4
Shorted if there is no external unit on RS485. This jumper works as ‘end of line’ jumper. If
one or more units are connected on RS485, only short on the last connected unit. JW4 on
all other units should be left open.
JW5
Normally open. To reset the password, place jumper here and power down the panel (both
AC power and batteries). Then power up the panel again, the password is restored to the
default after system startup. Once the system has reset,
REMOVE
the jumper from the pins
at JW5.
JW6
Normally open to BLOCK configuration via modem, PC with a UIMA converter module or a
CFG-300 Configuration Tool. Place jumper here to ALLOW any type of configuration.
