OMNISCANNER
A.28 High-Voltage Input Protection
The test interface withstands input hazard conditions that arise from normal
telephone interfaces (48 VDC at less than 80 nA) or 24-VAC power used to power
many telephone keysets. The unit detects when a voltage of greater than +15 volts
is applied on the inputs and sounds a warning to alert the user to remove the
hazard condition immediately to prevent possible damage to the input circuits.
NOTE
Measurements cannot be performed when hazard conditions are
present.
