A suppression system provides more effective protection for communication stations with distributed radio and power systems. The suppression system provides surge protection both locally close to the radio station building where the power plant and telecommunication equipment are located and remotely next to the radios and antennas located outside of the building on the communication tower. Local and remote suppression units may include monitor circuitry that monitor remote and local DC voltage levels and alarm conditions. The alarm conditions may include over-voltage protection failures, intrusions, and/or water infiltration. Displays on both the local and remote suppression units identify the voltage levels and alarm conditions.
