Device Alerts are unsolicited messages sent by Devices to DCC Users. The GB Companion Specification (GBCS) lists and defines the structure of these Alerts, distinguishing between mandated and non-mandated Alerts.
GBCS Parse software allows any new non-mandated Alerts of the right format (as specified by the GBCS) sent by Devices to be passed to the DCC User. These new non-mandated Alerts have been captured in the GBCS within Table 16.2 following the November 2021 SEC Release. Any new non-mandated Alerts will be captured temporarily in a register until they are adopted by the SEC.
Please find the latest version of the NGNM Alerts Register below:
Suppliers and manufacturers have a general (but non-regulatory) responsibility to ensure all Alerts supported by their Devices beyond those specified in the SEC are captured in the register until they are adopted by the SEC.
