Charging Status and Low Battery LEDs
Charging Status LED (Yellow)
The yellow LED shows the charging status of the battery. Figure 4 shows its location.
•Yellow LED off
The yellow LED is off when the battery is fully charged.
LED off when battery is missing, shorted, or reversed: The charging LED is off when the battery is missing, shorted, or reversed, but the red Low Battery LED is flashing.
•Yellow LED on
A steadily lit yellow LED indicates the battery float voltage is below 13.8. If AC is present the battery is charging.
LEDs Off When Normal

The yellow LED also comes on when the combined current draw from all outputs exceeds 1.4 Amps. This is normal under alarm conditions for
•Yellow LED flashing once per minute
The yellow LED normally flashes once per minute as the D9112 checks the battery.
•Yellow and red LEDs flashing once per minute
The yellow and red LEDs flash on once every minute when current draw for devices connected to the power outputs exceeds 1.4 Amps and the battery is missing.
Low Battery LED (Red)
The red LED shows the condition of the battery. Figure 4 shows the location of the LED.
•Red LED off
The red LED is off when the battery is fully charged. When battery voltage drops below 12.1 VDC, the red LED comes on. It goes out when battery voltage reaches 13.7 VDC.
•Red LED on
A steadily lit red LED indicates battery voltage has fallen below 12.1 VDC. The LED goes out when battery voltage reaches 13.7 VDC.
•Red LED flashing (same rate as green LED)
The red LED flashes with the green Operation Monitor LED when the battery is missing or shorted.
Reset required for shorted battery: If the D9112 detects a shorted battery, the battery remains disconnected and the red Low Battery LED continues to flash until you reset the panel.
No missing battery with D192A Using a D192A with a D9112, prevents the D9112 from recognizing a missing battery condition.
•Red and yellow LEDs flashing once per minute
The yellow and red LEDs flash once every minute when current draw for devices connected to the power outputs exceeds 1.4 Amps and the battery is missing.
