This guide provides a complete and professional procedure for commissioning a Building Management System (BMS), including safety precautions, integration checks, and testing requirements.
🧷 Safety Preparations
Ensure engineers and technicians wear appropriate PPE.
Clear the area around the BMS panel to allow easy and safe access.
Unlock and open the BMS panel using the provided keys.
Verify that there is no power in the system using a multimeter.
🔧 Cable and Connection Inspection
Check that all terminated cables are tightly secured and no conductors are exposed.
Confirm cable terminations are as per the wiring diagram and cable schedule.
Perform the following safety checks:
Line-to-neutral continuity
Earth connection verification
Enclosure body grounding
Transformer earthing confirmation
🔗 Integration Verification
Verify all integration cables are properly connected:
System
Protocol
Cable Type
Fire Alarm System
BACnet/IP
CAT-6
Lighting Control
BACnet/IP
CAT-6
Water Meters
Modbus/RTU
Serial
Multifunction Meters
Modbus/RTU
Serial
VRV System
BACnet/IP
CAT-6
Confirm integrated systems are configured by coordinating with the BMS supplier.
For IP-based connections, ensure suppliers use BMS-designated IP ranges.
All integrated systems must allow BMS discovery of their data points.
⚡ Power Supply & Breaker Verification
Ensure all secondary breakers and fuses are in the OFF position.
Measure incoming power (L-L and L-N) using a multimeter; confirm 380V/3PH/60Hz as per drawings.
After verification, switch ON the MCCB.
Measure voltage post-MCCB and record.
Sequentially activate breakers/fuses and confirm power output.
💻 DDC & Software Commissioning
Once power is verified, the panel is ready for system integration.
Connect a laptop to the DDC and enable communication.
Launch commissioning software and enter the third-party integration parameters.
Discover the integrated system’s data points.
If successful, define and store them in the BMS controller.
Validate values against actual system data.
For meters, verify values from the physical display.
📊 HMI & Finalization
Check the HMI screen to ensure all signals and values are correctly displayed. Create users with different administrative roles. Upload and verify graphics on EWS and OWS at the Control & Admin buildings.
Secure and lock the BMS panel.
Conduct final housekeeping.
Inform the contractor/consultant that the system is ready for handover.
