24 1200C-2000C Fire Alarm Control Panel, Repeater, and Black Box Installation Manual
Connecting the batteries
The control panel requires two 12V, 7 to 45 Ah rechargeable sealed lead-acid
batteries (see table below).
Batteries must be installed in series using the bridge provided and connected to the
BAT CH terminals on the PS1200N power supply interface (see Figure 15 on page 17).
Polarity must be observed. No other equipment may be connected to the battery
terminals.
