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.
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 non-fire systems when
sirens or bells draw more than 1.4 Amps. If the LED comes on regularly for extended
periods or doesn’t go out, check the current draw for devices connected to the power
outputs. See the
Power Outputs
section in this manual for instructions.
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.
