About this file

This is a fire alarm reporting diagram for a Siemens Desigo system showing a distributed network architecture across multiple facilities. The schematic illustrates nine fire alarm control units (FAC) deployed at various locations: Trinity Powerplant, Shasta Powerplant, Shasta Dam, Shasta Upper Vista House, Lewiston Powerplant, Shasta Maintenance Center, JF Carr Powerplant, Spring Creek Powerplant, Keswick Powerplant, and Keswick Office Building. Each facility is equipped with a Bosch D1218 battery (12VDC, 18AH) for backup power and an IP DACT (Digital Alarm Communication Transmitter) module for VoIP phone line connectivity. The central hub is a Bosch Receiver with PC located at Shasta Powerplant, which aggregates alarm signals from all remote facilities through LAN/WAN connections. The diagram indicates that the Spring Creek Powerplant and one additional LAN/WAN connection fall within the defined scope of work, as demarcated by the dashed box. All facilities maintain redundant communication paths through VoIP phone lines and network connections to ensure continuous fire alarm monitoring and reporting capabilities across the interconnected system.
