Edwards 4-CPU — Central Processing Module for the EST4 life safety platform.The 4-CPU pulls data from the local rail modules in real time and is the node's link for network communication, event logging, audio control and central-station reporting. EST4 networks have no master: each node is a peer, self-configuring over IPv6, and the pluggable SFP controllers let one card serve copper, CAT5 or fiber. 211 mA at 24 Vdc 20,000 event history plus 10,000-event History Freeze Two SFP slots for hot-swappable network controllers One USB Type A host port, one USB Type B device port Up to 19 additional local rail modules per node Mounts in the first two rail spaces of the upper 3-CHAS7 chassis 32 to 120°F (0 to 49°C), 0 to 93% RH noncondensing UL, ULC, FM, CSFM listed; 0.95 lb This is an EST4 module and will not serve an EST3 panel — the EST3 processor is the 3-CPU3, a different card. SFP network controllers, the 4-COMREL relay module and the 4-AUDTELS audio/telephone riser are ordered separately.
