In the 2026 Malaysian regulatory landscape, a Smoke Control AHU (often referred to as a Smoke Spill AHU or Mechanical Smoke Extraction system) is a critical life-safety asset. Governed by the Fire Services Act 1988 (Act 341), the Uniform Building By-Laws (UBBL) 2026, and MS 1780:2017/2026, these units are engineered to extract toxic fumes during a fire to keep escape routes tenable for occupants and provide visibility for emergency responders.
At EKG (Malaysia) SDN BHD, we ensure your smoke control systems are Sterile, Silent, and Statutory-Compliant, bridging the gap between mechanical efficiency and life-safety containment.
As of February 3, 2026, JBPM (BOMBA) has intensified enforcement of smoke control protocols. Compliance is a non-negotiable requirement for obtaining or renewing a Fire Certificate (FC).
Extraction Rate: Under MS 1780, smoke spill systems must achieve a minimum of 10 Air Changes Per Hour (ACH) in the fire-affected zone.
Temperature Integrity: All components, including the fan, motor, and casing, must be certified to operate at 250°C for at least 120 minutes (FRP 120).
eFEIS 2.0 Registration: Every smoke control component must carry the BOMBA "K" Mark and be registered in the eFEIS 2.0 digital ledger to be legally valid during a statutory audit.
A Smoke Control AHU is distinct from a standard cooling unit because its internal components are designed to withstand extreme thermal loads.
| Component | 2026 Engineering Standard | Purpose |
| High-Temp Motor | Class H Insulation / IP55 | Prevents motor seizure or burnout during high-heat smoke extraction. |
| Fire-Rated Ducting | MS 2586:2026 (1.2mm min) | Maintains integrity at 250°C to prevent duct collapse and smoke leakage. |
| VFD "Fire Mode" | Hard-wired Override | Bypasses all thermal protection logic to keep the fan running until failure. |
| FR Cabling | MS 2116 Class C | Ensures the power supply remains intact throughout the evacuation window. |
During a fire, the EKG Smoke Spill Protocol follows a millisecond-precision automated logic:
Fire Signal Initiation: The Fire Alarm Monitoring System (FAMS) detects smoke and triggers the fire panel.
Standard AHU Shutdown: All non-safety AHUs receive an Automatic Fire Signal AHU Shut-off to stop the spread of smoke.
Smoke Spill Activation: The Smoke Control AHU ramps up to 100% capacity to begin active extraction.
Make-Up Air Interlock: Motorized fresh air louvers open to introduce replacement air, preventing a vacuum that would trap occupants behind heavy fire doors.
To secure your AHU Safety Permit, EKG engineers coordinate the official witness test with BOMBA:
Smoke Visualization Test: Using non-toxic smoke bombs to verify the effective extraction path and negative pressure in the fire zone.
Static Pressure Audit: Ensuring the fan can overcome the resistance of fire-rated ducting and MS 558 certified motorized dampers.
Digital Twin Handover (LOD 500): All commissioning logs and certificates are uploaded to your building’s Digital Birth Certificate for the mandatory 5-year periodic audit.
Technical Integrity: Our systems are designed by mechanical engineers specializing in the intersection of thermodynamics and active fire protection.
EECA 2024 Alignment: We utilize high-efficiency axial fans that meet energy benchmarks during non-emergency "Air Purge" cycles.
GITA Support: Documented compliance with 2026 BOMBA standards is essential for claiming the 100% Green Investment Tax Allowance.
