Abstract
A fire protection system includes a first transceiver communicatively coupled with a first end of a communication link; a second transceiver communicatively coupled with a second end of the communication link and configured for communicating a signal with the first transceiver via the communication link; a first coupling/decoupling circuit configured to provide overlayed power by overlaying power from a first power source onto the signal at the first end of the communication link; and a second coupling/decoupling circuit configured to provide separated power by separating the signal from the overlayed power at the second end of the communication link, wherein the separated power is configured to power the second transceiver.
