Does the opticalCON powerMONITOR offer output pins which can be linked to an external alarm unit?

The powerMONITOR contains an internal switch between pin 2 and 3.

To activate an external device (e.g. horn, signal lamp, microcontroller, etc.) set a High-signal (e.g. 3.3V) on pin 2.

If the alarm from the powerMONITOR starts the switch closes and the High-signal will be passed to pin 3 and the alarm unit at the end.
