2.9 Low Input Alarm

This output signals the Power Management circuit (PM104) or external circuitry that main input power has failed. The Low Input Alarm signal has a 100K current limiting resistor in a series.

If the PM104 is not installed, then external circuitry can access the Low Input Alarm output on connector IC3-7.
