 "summary": "A single-room differential pressure monitor sold by Siemens as a standard BACnet device. Its point map has one pressure input, alarm limits and timers, a door input, an alarm-active flag, relay and alarm settings, and selectors for the analog output type, pressure unit and room type. It has no application point; the field panel assigns a project application number.",

 "notes": [
  "The point map has no access column; AI and BI are shown read-only and AV, BV and MV writable (the map lists them as logical outputs).",
  "Pressure units follow the pressure unit selector MV 2 (inWC, Pa or cmWC); inH2O is shown here. The map's footnote calls this point 18 (MV_3); point 18 is MV_2 in the table.",
  "The analog output units (mA or V) follow MV 1.",
  "Most binary objects print only placeholder state text (\"Inactive Text\" / \"Active Text\"); those states are left blank here.",
  "Besides the 19 points, the map lists event enrollments and notification classes 1-3 for alarm, pressure out of limit and door open.",
  "The point map does not name the data link. Setra's PICS for the SRCM (Room Condition Monitor, SS-SRCM-BAC-PICS Rev A) lists BACnet MS/TP master at 9600, 19200, 38400 and 76800 baud."
