Output Supervisory
This screen lets the viewer see the current supervision readings and status for bells,
releasers and auxiliary power circuits. These values should be in the range of 130 to 150
for Vhi and 10 to 20 Vlo. If the numbers are jumping all over the place, there may be a
hardware fault with the panel.
