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.
