Adding the Charger for Additional Current Due to internal fuses, the maximum alarm
current that can be drawn from the batteries and passed through the charger’s two output
circuits is limited to 10 amps maximum (each circuit). The PS-12600 batteries, however,
are capable of supplying up to 45 amps of current in alarm. The remaining 25 amps of
alarm current can be drawn directly from the battery terminals to supply Notification
Appliance Circuits, control modules and other alarm devices as illustrated in Figure 12
