FEMA’s Integrated Public Alerts and Warning System Open Platform for Emergency Networks (IPAWS-OPEN) enables emergency messages to reach the public by radio, television, cell phone, National Oceanic and Atmospheric Administration Weather Radio, internet-based systems and by products made by Emergency Alert System encoder/decoder equipment manufacturers.

IPAWS-OPEN Capabilities

IPAWS-OPEN receives and authenticates messages from state, local, tribal and territorial emergency management officials and routes them to IPAWS-compliant public alerting systems.

The platform uses the Common Alerting Protocol (CAP), an international standard used by IPAWS to send public alerts and warnings. Existing state or locally owned and operated warning systems – such as sirens, highway signs or emergency telephone notification systems – can be designed to send alerts from IPAWS-OPEN.

Public safety organizations can use the Common Alerting Protocol to exchange incident reports and related information between different IPAWS-OPEN-compatible software systems.

IPAWS-OPEN is compatible with National Weather Service (NWS) message dissemination systems, including NOAA Weather Radio and HazCollect. IPAWS-OPEN may be used to route messages to the NWS gateway, which results in an increased number of channels that can be used to warn the public.
