The EAS provides a direct interface between the Site Controller and various
site alarms. Figure 10-2 shows a functional block diagram of the EAS.
The EAS is configured for 48 dry contact input sensors and 8 relay closure
outputs. Each I/0 provides 4000V of isolation between field wiring and
sensitive control circuitry.
