 "summary": "The AMC-1DBx is a gas detection controller for large sensor networks. Over BACnet IP it exposes 4,119 fixed objects: a system state, then for each possible sensor a raw value, a cause state and a status string, and the same kind of blocks for relays, zones and analog outputs, plus file objects for logs, database and firmware. Configuration is not available over BACnet.",

  "Objects come in fixed instance ranges, one object per sensor, relay, zone or output. Only the first object of each range is listed; the range is in each description (e.g. AI 0-987 = sensors 1-988).",
  "Object names are not printed; the group labels from the object list are used.",
  "Analog outputs are Analog Input objects AI 988-1115. OctetString Value objects (OS) carry packed status bytes.",
  "All objects are read-only except File objects; some support Out-Of-Service for testing interlocks.",
  "Cause states are 6-bit masks reported as values 1-32, where 32 = All Clear."
