The FEMA National Radio System (FNARS) "Provides Primary Entry Point service to the Emergency Alert System", and acts as an emergency presidential link into the EAS. The FNARS net control station is located at the [[Mount Weather Emergency Operations Center]].<ref>{{cite web | url=https://www.cdc.gov/phin/conference/04conference/05-27-04/Session_12D_Ross_Merlin.pdf | title=Communications Systems for Public Health Contingencies | last=Merlin | first=Ross Z. | year=2004 | publisher=DHS/FEMA Wireless Program Management Team | archive-url=https://web.archive.org/web/20080625023050/http://www.cdc.gov/phin/conference/04conference/05-27-04/Session_12D_Ross_Merlin.pdf | archive-date=June 25, 2008}}</ref>

Once an EAN is received by an EAS participant from a PEP station (or any other participant) the message then "daisy chains{{'"}} through the network of participants. "Daisy chains" form when one station receives a message from multiple other stations and the station then forwards that message to multiple other stations. This process creates many redundant paths through which the message may flow, increasing the likelihood that the message will be received by all participants and adding to the survivability of the system. Each EAS participant is required to monitor at least two other participants.
