Zusammenfassung:	A computer-implemented system includes the following. A remote terminal unit (RTU) is configured to receive alarm information and communicate alarm event information to a control center. An optical master unit (OMU) is configured to receive alarm information from sensors at remote locations. A circuit board is configured to serve as a middle device between the RTU and the OMU. A circuit board includes a microcontroller that communicates with the OMU and processes replies from the OMU to confirm the existence of and identify the type of an alarm at a particular remote location. The circuit board also includes multiple output relays connected to the RTU and corresponding to remote alarms, each output relay associated with a particular sensor at a remote location. The computer-implemented system also includes an input relay for communicating with the OMU.
