Smoke Control System Commissioning by EKG M&E Sdn Bhd
In the high-rise commercial landscape of KL and PJ, the commissioning of a smoke control system is the most critical step before a building can be occupied. EKG M&E Sdn Bhd specializes in Smoke Control System Commissioning (T&C), providing the technical validation and documentation required for BOMBA (Fire and Rescue Department of Malaysia) approval and the issuance of your Fire Certificate (FC).
The Commissioning Framework: Proving Life Safety
Commissioning is not just a "functional check"; it is a rigorous stress test of the building's mechanical "lungs." We follow a structured protocol to ensure every component survives the extreme conditions of a fire.
1. Mechanical Component Verification
We verify that the physical hardware matches the engineered design and survives thermal stress.
-
High-Temperature Fan Testing: We run Smoke Spill and Pressurization Fans at 100% capacity. We measure current (Amps), voltage, and vibration to ensure Class H motors are ready to run at 250°C for 2 hours.
-
Damper Integrity: We cycle every Motorized Fire and Smoke Damper. We verify that they close (to isolate zones) or open (to extract smoke) within the mandatory 60 seconds.
2. Airflow and Pressure Mapping
We use calibrated instruments to prove the "Pressure Shield" is effective.
-
Differential Pressure (DP) Testing: We measure stairwell pressure to ensure it maintains 50 Pa relative to the floor. We also check Lift Lobby Pressurization (typically 15 Pa) to ensure smoke cannot enter escape routes.
-
Door Opening Force: We use digital force gauges to ensure that under full pressurization, the force required to open an exit door does not exceed 110 N, allowing for safe evacuation of all occupants.
-
Extraction Rate (10 ACH): Using anemometers, we calculate the total exhaust volume to confirm the system meets the mandatory 10 Air Changes Per Hour for smoke spill.
3. Control Logic and Integration (The "Fire Mode")
We simulate an alarm to test the communication between the Main Fire Alarm Panel (MFAP) and the ventilation system.
-
HVAC Shutdown Interlock: We confirm that when the fire alarm triggers, all general office AC units shut down instantly to prevent the mechanical mixing of smoke.
-
VFD Override: We verify that Variable Frequency Drives (VFDs) enter "Fire Mode," bypassing all energy-saving and motor protection limits to prioritize operation over equipment longevity.
4. Hot Smoke Visualization (The Final Proof)
For complex atria or lobbies, we perform a Hot Smoke Test. By using non-toxic, heated smoke, we provide visual proof of the "Smoke Plume" behavior and the stability of the "Clear Layer."
