 "summary": "The MB-BAC-WA1/2 module connects up to 2 fire or smoke dampers to BACnet MS/TP (or Modbus RTU). Per channel it has an operating-mode object, a safe position, an open/close command, position feedback, an alarm object and run-time and heartbeat timers; a test object starts a damper test for all channels. 20 objects in total; the object names are factory defaults and can be renamed.",

 "notes": [
  "AV 1-6 and MV 3-12 are disabled by default; they appear once Damper1..2 (MV 1-2) sets a channel operating mode.",
  "Most objects only exist in Motorised_Damper mode; ActuPos..a is only used with the two \"Only_Limit_Switch\" modes (two mechanical dampers per channel).",
  "Object names, descriptions and state texts are writable and stored in EEPROM; the names here are the factory defaults.",
  "COV is supported for ActuPos, ActuPos..a and Alarm objects (max. 10 subscriptions).",
  "The device Model_Name reads \"MB-BAC-WA1B3\" in this manual."
