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.

Figure 4: Charging and Battery LEDs

• 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 system 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.
Low Battery
• 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.
Missing Battery
• 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.
Missing Battery and Over Current
• 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.
