Low-voltage surge protection device designed to reduce transient overvoltage on compatible alarm, communication, and control signal lines.
A Signal Line Surge Protector protects compatible signal circuits by limiting transient voltages and diverting surge current through the designed protective path. The device must match the signal voltage, operating current, bandwidth, line configuration, and grounding arrangement of the circuit being protected.
