2.8 Battery Monitor Board Wiring

The battery monitor board is a unique monitoring and test board for the Matrix range of control panels,
including the Matrix 832, 832+, 424 and Matrix 6. Connect the battery monitor board to the control panel as
illustrated below.

2.8.1 How the Battery Monitor Board Works

Once the mains supply is connected to the battery monitor board, it will continuously monitor the battery. If
the battery supply is good, the LED on the battery monitor board will be illuminated. If there is no mains
supply and the battery is low, the control system and battery monitoring board switch off, and the LED is no
longer illuminated.
NOTE 1: When a new battery is fitted and there is no mains supply, the engineer should press the
reset button to provide battery power to the board.
Battery Test
This option is disabled when the mains power is removed.
24 Hour Test Mode
24 Hour Test Mode is enabled by fitting header B. If enabled, and the battery voltage drops below 11.5 Volts,
the battery supply is cut off from the Matrix for 5 seconds (enabled by fitting header A). A solid-state relay is
turned on at the same time as the 5-second cut-off and gives an additional indication that the battery is low.
This relay can be connected to the panel between outputs N/C and a zone input.
NOTE 2: If the zone connection is used, adjust header J1 to the relevant zone setting, i.e., Normally
Closed, End Of Line or Single End Of Line. The zone setting of the battery monitoring board must be
the same as that of the control panel.
RT.A low state on input RT can initiate a battery test.
