High Voltage Protection

The PentaScanner+/PentaScanner/PentaScanner Cable Admin, 2-Way Injector+/2-Way

Injector and Super Injector+/Super Injector are designed to withstand input hazard voltage conditions that arise from normal telephony applications such as 48 VDC at less than 80 ma or 24 VAC used to power many 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. Tests cannot be performed when hazard conditions are detected on the inputs.
