Smoke Extraction System Inspection

Short answer: Smoke extraction systems are systems that control the smoke generated during a fire, keeping escape routes clear and facilitating intervention. Fans, dampers, panels, and pressurization are controlled within the framework of TS EN 12101 series and BYKHY (Fire Safety and Environment Regulations).

A significant proportion of fire deaths are caused by smoke. A malfunctioning exhaust fan, an unopened damper, or inadequate stairwell pressurization can fill escape routes with smoke, making evacuation impossible.

Periodic inspections ensure that smoke control scenarios are implemented effectively under real-world conditions, thereby protecting lives and improving intervention capabilities.

What is checked?

  • Smoke exhaust fans and activation.
  • Smoke/heat dampers and motorized actuators
  • Staircase/corridor pressurization fans and pressure differential
  • Automatic triggering (integration with detection)
  • Control panel, manual commands and feedback.
  • Fresh air/vent and direction control

Method and Scenario Testing

The inspection includes triggering each smoke control zone according to the fire scenario, measuring fan/damper operation, and measuring the required pressure difference in pressurization systems. TS EN 12101 The series defines the component and performance requirements for smoke and heat control systems. Integration with the detection system is also tested.

Legal Basis and Period

Smoke extraction and pressurization systems must be regularly inspected and reported by authorized personnel in accordance with BYKHY and TS EN 12101 series standards.

Common Nonconformities

  • Exhaust fan that doesn't automatically activate
  • Stuck or malfunctioning damper
  • Insufficient stairwell pressurization pressure.
  • The integration of detection and smoke control is broken.

Frequently Asked Questions

Why is stairwell pressurization necessary?

Keeping the escape staircase free of smoke ensures safe evacuation; this is verified by measuring the pressure difference.

How are dampers tested?

Its opening and closing, as well as feedback signals, are controlled by a trigger command.

Which standard is essential?

TS EN 12101 series and BYKHY are taken as the basis.
