7. Connect the battery, referring to Figure 2-10.
The FA2000C runs a brief battery test once a minute to determine if battery leads are connected and runs an
extended battery test every 24 hours to determine if battery capacity is low (less than approximately 11.5VDC). If
a low battery condition exists the FA2000C's built-in Battery Trouble LED will light and a rapid beeping sound will
be heard from its built-in warning buzzer. In addition, if a keypad is on the system, it will be displayed at the
control's keypad(s). These indications will stop when the low battery condition has been restored to normal (for
several minutes).
The FA2000C control comes with a dual battery harness, which allows up to two 12VDC lead acid batteries to be
connected in parallel to the control. Connect the battery(s) to the control using the dual battery harness as shown in the
figure below.
When connecting batteries in parallel:
• Use batteries from the same manufacturer and with the same voltage and capacity rating.
• Use batteries with approximately the same age and state of charge.
• Use cables provided and observe polarity.
• It is recommended that all batteries be replaced at the same time, even if only one battery has become weak.
The system provides monitoring of the system battery's charger circuit. Program field 75 with the charger circuit

NOTE: This fuse is intended to prevent the risk of battery harness flame-out when two batteries are used and one
battery is connected with proper polarity and the other battery is connected with reversed polarity. This fuse will not
open circuit under any other condition. Observe proper polarity when making connections!
