DIP Switch and Jumper Selections for Main Board and Adder Modules
6.3 MR-2300-NC4/2 Output Class-A Converter Adder Module
Figure 11 MR-2300-NC4/2 Output Class-A Converter Adder Module
Indicating circuits must be wired from the MR-2300-NC4/2 to the main Fire Alarm board. For
example indicating circuit 1 positive (red wire) and negative (black wire) is wired from the
Class A converter module to the positive and negative terminals of Indicating circuit 1 on the
Main Fire Alarm board.
The actual indicating zone is wired from the SIGNAL OUT positive and negative to the
signaling devices and then wired back to the SIGNAL RET positive and negative.
6.4 Relay Adder Modules (Models MR-2312-R12 and MR-2306-R6)
6.4.1 MR-2312-R12 Twelve-Relay Adder Module
The ribbon cable from P1 of the MR-2312-R12 is connected to P6 on the Main Fire Alarm
Board. The jumpers located above each relay on the MR-2312-R12 are used to configure the
relays. The jumpers located below the relays are used to select either normally open contacts
or normally closed contacts.
