4.8.1 Battery Connections
A FireFinder PLUS requires two (2) 12 volt batteries (TB9). The batteries should be placed into the
bottom right hand side of the cabinet.
A red and black lead coming from TB1 on the Brigade Board will be clearly seen in the same area, this
lead is to be connected to the batteries red to positive and black to negative once the system is
operating on Mains supply.
Battery size is dependent on the system configuration and can vary from 12 AHr to over 100 AHr.

Note:
Refer to Ampac’s battery calculation tool to calculate the required battery size.
TB9 is located on the bottom
right hand side of the board
