In the 2026 Malaysian regulatory environment, a Fire Damper Integrated AHU Installation is a critical engineering requirement for building safety. Under the Fire Services Act 1988 (Act 341) and the Uniform Building By-Laws (UBBL) 2026, fire dampers are mandatory wherever ductwork penetrates a fire-rated wall or floor slab. This integration ensures that the AHU system does not facilitate the spread of flame and toxic smoke between fire compartments.
At EKG (Malaysia) SDN BHD, we treat the damper-to-AHU interface as a primary life-safety junction, ensuring your installation is Sterile, Silent, and Statutory-Compliant.
To obtain an AHU Safety Permit, all integrated fire dampers must be certified and auditable.
MS 558:2024 Standards: Dampers must be tested and certified to Malaysian Standards (or international equivalents like UL 555) for a minimum 2-hour fire-resistance rating.
eFEIS 2.0 Registration: Every damper installed must be registered in the BOMBA digital system, featuring a valid BOMBA "K" Mark sticker for physical inspection.
Automatic Interlock: The dampers must be integrated with the Automatic Fire Signal AHU Shut-off protocol. When the damper closes, the IE5 EC Fan Wall must simultaneously shut down to prevent high-pressure duct rupture.
A "Fire Damper Integrated" setup requires precision at the point of penetration to maintain the wall's fire rating.
Motorized vs. Fusible Link: While traditional fusible links exist, 2026 standards for Grade-A offices prioritize Motorized Fire & Smoke Dampers. These are interlocked with the Fire Alarm Monitoring System (FAMS) to provide active protection before flames even reach the unit.
Expansion Clearance: We engineer the "sleeve" installation to allow for thermal expansion of the damper frame during a fire. A damper that is grouted too tightly will warp and fail to close, a common cause of BOMBA audit failure.
Breakaway Connections: All ductwork connections to the damper sleeve must be "breakaway" type. This ensures that if the duct collapses during a fire, it will not pull the damper out of the fire wall.
| Component | 2026 Technical Requirement | Engineering Purpose |
| Intumescent Fire-Stop | BOMBA-approved mastic/mortar | Seals the gap between the damper sleeve and the wall. |
| Sleeve Gauge | Minimum 1.6mm (16 GA) | Provides structural integrity during extreme heat. |
| Access Door | Minimum 450mm x 450mm | Required for mandatory periodic inspection of the damper blades. |
| Fail-Safe Actuator | Spring-Return (24V/230V) | Automatically closes the damper upon loss of power. |
Before commissioning, EKG engineers perform a dual-validation witness test:
The "Cold" Test: Verification that the damper blades rotate freely and that the Duct Smoke Detector triggers the motorized actuator.
The "Interlock" Test: Confirmation that the AHU motor shuts down immediately upon damper closure to protect the integrity of the ductwork and the TB2 Thermal Break casing.
Passive Audit: Inspection of the fire-stop mortar to ensure a smoke-tight seal around the penetration.
Technical Integrity: Our integrations are designed by mechanical engineers who specialize in the intersection of thermodynamics and active fire protection.
EECA 2024 Alignment: We utilize high-efficiency aerofoil-blade dampers that meet fire ratings while maintaining the low resistance needed to satisfy your Specific Fan Power (SFP) energy targets.
GITA Support: Documented compliance with BOMBA fire damper standards is essential proof for claiming the 100% Green Investment Tax Allowance.
