NOTE
The Emergency Off alarm will also freeze the SCC History Status buffer with the Auto Transfer to Bypass alarm (if the load is on the UPS system when the alarm condition occurs).
The History Status buffer does not resume collecting new frames until the fault is cleared and the Alarm Reset pad is pressed for more than 5 seconds (or until the screen clears).
