The Edwards 4-CPU-E is the central processing unit of the Edwards EST4 life safety control platform. It manages the data generated by the local rail modules and is the hub for system-wide network communications. It controls audio data and event logs, and it is the link to central monitoring facilities.
Two SFP slots take hot-swappable network controllers, so you choose the cable type at each panel: twisted pair, CAT5, multimode or single-mode fibre. Panel data, voice audio and firefighters' telephone all run over the same network cabling, with no separate interconnections needed.
