1.BMS Operator Roles & Responsibilities

I am writing about the roles and responsibility of BMS operators by considering that you have basic understating about what is BMS and how it is used in building for controlling and monitoring.
As a BMS operator, you will be assigned as supervisor category to monitor the BMS Software and reports to the senior engineer as per their facility management procedures of building equipment’s parameters shown in graphical live values.
In Addition to this, BMS has basic features like generates alarms if any fault occurs in the building, recording various values called as trend-log and scheduling to on/off the controlling the equipment
As a BMS Operator, you must be aware how HVAC equipment of air handling unit, fan coil unit, the variable air volume in building working so that BMS operator can adjust the temperature setpoint based on the client requirement.
BMS operator has to know how to handle alarm management in BMS software.
When the equipment fails to run on the field or not working properly; the respective controller triggers the alarm based on condition written in the program.
    Eg: If the Room temperature reaches above 30 degree Celsius, BMS Software generate alarms and that should be
  • Checked – BMS Operators has to inform the respective team the check the respective Unit serving room.
  • Acknowledge – BMS operators have to acknowledge the alarm.
  • Disable – if the respective room is vacant or not used, BMS operator can disable the alarm to not to raise again.
  • Ignore – Based on the alarming nature about which is not a high priority.

BMS Operator can able to communicate with the respective engineer to highlight the issues noted on BMS.

  • if any field equipment/BMS controller not working or communicating, then BMS Operator can be able to communicate with respective vendors and get the field issues resolved and should cross-check with BMS System to ensure the working condition of BMS.
  • BMS Operator can be able to prepare a report and submit to his/her focal point.
BMS Operator must know various documents related to BMS, they are
  • IO Schedule,
  • IO termination drawings.
  • Network schematics.
  • The sequence of operation.
  • Control Schematics.
  • Network Schematics
  • Specifications
BMS Operator must know basic idea about other ELV systems in the building and how they are interfaced with BMS.
Able to differentiate and highlight the issues to the right team based on the various problems raises in the building related to BMS, For example
  • If the AHU Equipment graphic page shows trip alarm; that Issues should be highlighted/informed to HVAC Team, not to BMS Vendors.
  • If the AHU not showing proper temperature values or not showing any values; that should be informed to BMS Vendors, not to HVAC Team.
  • After informed/confirmed by HVAC team about the trip alarm and if field showing/working in normal; then it should be informed to BMS vendors about the false alarm.
