Staircase & Lobby Pressurization Systems

Staircase and Lobby Pressurisation Systems are life-safety ventilation systems designed to prevent smoke infiltration into escape routes during fire emergencies. These systems maintain positive air pressure within staircases and fire lobbies to ensure safe evacuation and unobstructed firefighter access.

We install and service Staircase Pressurisation Systems, Fire Lobby Pressurisation Systems, Lift Shaft Pressurisation Systems, Combined Stair & Lobby Pressurisation Systems, and Multi-zone Pressurisation Systems. System configuration depends on building height, occupancy classification, and fire code requirements.

Yes, we offer comprehensive Annual Maintenance Contracts (AMC) for pressurisation systems including fan inspection and lubrication, motor alignment and electrical testing, differential pressure verification, damper inspection and testing, fire alarm interlock testing, emergency power testing, duct leakage inspection, and compliance readiness checks. Customized AMC plans ensure uninterrupted fire safety compliance.

Insufficient pressure differential is commonly caused by fan motor failure, damper malfunction, control panel faults, pressure sensor calibration issues, air leakage problems, or fire alarm interlock malfunction. We provide rapid corrective maintenance with root cause analysis to restore code-compliant smoke protection performance.

Our installation includes pressurisation fan installation, supply air duct fabrication and erection, fire-rated duct installation, motorized fire damper installation, pressure relief damper integration, automatic control panel installation, smoke detector integration, differential pressure sensor installation, louvers, fresh air intake arrangement, electrical wiring, emergency power integration, and vibration isolation mounting. Engineering focus includes pressure differential calculation, door opening force compliance, and fire-rated duct routing.

Our commissioning services include differential pressure measurement, door opening force testing, airflow CFM validation, static pressure testing, smoke simulation testing, fire alarm interlock testing, emergency power testing, and relief damper functionality testing. Detailed commissioning and compliance reports are provided for submission to fire authorities.

Yes, we execute retrofitting services including installation of pressurisation systems in older buildings, fan capacity upgrade, fire-rated duct replacement, control panel modernization, integration with upgraded fire alarm systems, and compliance improvement works. Retrofitting ensures regulatory approval and improved occupant safety.

We provide fire alarm panel integration, automatic start/stop logic configuration, emergency power integration, pressure-based control automation, BMS monitoring integration, and alarm/fault indication system setup. Automation ensures immediate activation during fire emergencies.

While life safety is primary, energy efficiency is improved through pressure optimization, fan efficiency analysis, leakage reduction, VFD integration (where permissible), and performance benchmarking. Optimized systems maintain safety while improving operational efficiency during testing cycles.

Life-safety systems require strict periodic inspection including fan inspection and lubrication, motor alignment and electrical testing, differential pressure verification, damper inspection and testing, fire alarm interlock testing, emergency power testing, duct leakage inspection, and compliance readiness checks. This ensures uninterrupted fire safety compliance.
