Yellow On Battery float charge is below 13.8 VDC. If AC is present the battery is
charging.
When the combined current draw from all outputs exceeds 1.4 amps.
This is normal under alarm conditions for non-fire systems with 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 section 5.0 Power Outputs for
instructions.
