SIA DC07 receiver to automation interface

SIA DC07 carries information from a receiver to monitoring automation. Check receiver status, event storage and operator handling as separate stages.

Overview#

SIA DC07 defines a common interface between alarm signal receivers and monitoring automation computers. It is the inside the monitoring centre handoff, not the protected premises to receiver transport.[^sia dc07]

premises ── alarm transport ──> receiver ── DC-07 ──> automation
                                  │                      │
                                  │ protocol status      ├─ event persistence
                                  │ line/receiver fault  ├─ operator workflow
                                  └ event normalization  └─ dispatch policy

Edition warning#

SIA's public standards page labels the available page DC07 2001.04.[^sia dc07] SIA's store separately describes a SIA DC07 2012 Standard.[^sia dc07 store] Because those official sources disagree, record the title page, revision date, addenda, interpretations, and receiver vendor's claimed edition from the actual purchased document. Don't silently call either one “the current DC07” in an implementation contract.

What the interface carries#

The public scope says DC07 covers a common receiver/computer format, codes identifying dialer protocols, and receiver conditions requiring technical attention. A developer facing canonical model should therefore separate:

• received subscriber event and its original dialer/protocol identity;
• receiver, line/channel, and account routing identifiers;
• receiver generated state, fault, and technician attention conditions;
• source timestamp, receiver timestamp, and automation ingest timestamp;
• protocol acknowledgement and automation persistence status;
• standard code versus vendor extension.

Don't discard receiver health messages as “not alarm events.” A receiver path failure or backlog may be more operationally important than a single subscriber event.

Adapter design#

• Implement the exact purchased edition's frame, code, continuation, acknowledgement, and retry rules.
• Bound message length and queued/unacknowledged records; backpressure must not silently drop high priority events.
• Commit accepted events durably before acknowledging if the protocol/product contract defines acknowledgement as acceptance.
• Use an idempotency key derived from stable receiver identity and the protocol's own correlation/sequence data, not only event text and wall clock time.
• Preserve unknown standard codes and manufacturer extensions with namespaces.
• Keep receiver connectivity state independent from individual account state.
• Reconcile state after reconnect; a live socket doesn't prove the backlog is complete.
• Sanitize raw fields before logs and UIs while retaining protected evidence for diagnosis.

SIA's public scope says independent code extensions make a device noncompliant and directs additions through SIA.[^sia dc07] In practice, isolate vendor extensions instead of passing them off as standard DC07.

Security model#

The public description doesn't claim modern cryptographic protection. Treat the receiver to automation network as a high trust conduit: segment it, mutually authenticate endpoints using a supported secure wrapper or network control, restrict receiver and automation management, encrypt across shared infrastructure, and monitor for reconnect storms, sequence gaps, unexpected receiver IDs, and code volume anomalies.

Never authorise dispatch solely because a syntactically valid DC07 message arrived. Automation must bind it to a configured receiver/channel/account relationship and apply site policy.

Safety boundary#

Use a synthetic receiver feed and non dispatch automation tenant. A receiver test mode isn't sufficient unless its downstream route is independently proven unable to call, notify, unlock, silence, or dispatch.
