Select a generating device type above to see the alert delivery pattern.
Message Pattern
Success Examples
The device detects the condition and generates GBCS event/alert code 0x8F8B.
The device transmits a GBCSResponse/DeviceAlertMessage to the DSP via the WAN. Payload contains alert code, timestamp, and use-case specific data (Use Case Specific Alert Structure).

View in GBCS Parser →DSP authenticates the GBCSResponse against the device certificate and validates the alert content.
DSP delivers the alert to the relevant Known Remote Party based on the alert code and triggering device type. The DUIS Response (sr:Response) wraps the raw GBCS payload in sr:GBCSPayload (base64).
The DCC User runs the received DUIS Response through the Parse tool, which decodes the GBCS payload and produces an ra:GBCSResponse (MMC) document containing the structured alert data.
