Short answer: Fire doors and dampers are passive fire safety elements that delay the spread of fire and smoke between compartments. Closure, airtightness, and hardware integrity are periodically inspected in accordance with TS EN and BYKHY standards.

Fire doors divide a building into fire compartments, delaying the spread of fire and providing time for escape. A door that is held open with a wedge, doesn't close, or has a damaged seal renders this barrier completely ineffective.

Periodic inspections verify that doors and dampers close automatically in case of fire, creating a barrier against smoke and flames.

What is checked?

  • Automatic closing (door closer) and full closing.
  • Hinge, lock, and panic bar functions.
  • Expanding (intumescent) wicks and smoke seals
  • Wing-frame clearances and sealing.
  • Fire dampers: closing with fusible fuse/actuator.
  • Label/certification and fire resistance duration (EI)
  • No wedges or obstructions

Method and Standard

The inspection includes verifying that the door closer fully closes the door, checking the integrity of the locking mechanism and seal, and confirming that the fire dampers close upon activation. For fire doors. TS EN 1634 The fire resistance principles are determined by the relevant TS EN standards requirements for dampers. The compatibility of the door's declared fire resistance class (e.g., EI60) with the installation is checked.

Legal Basis and Period

Fire doors and dampers must be regularly inspected and reported on by authorized personnel in accordance with BYKHY and relevant TS EN standards.

Common Nonconformities

  • Fire door held open with a wedge/block
  • Door closer that doesn't close completely or is misaligned
  • Worn-out expansion wick/smoke seal
  • Fire damper that does not close with a trigger.

Frequently Asked Questions

Can a fire door be left open?

No; however, it can be kept open if an automatic gripper (closing type) integrated with the sensing system is used.

What does EI60 mean?

It states that the door has 60 minutes of fire resistance in terms of integrity (E) and insulation (I).

What is a fire damper?

It is an automatic closing element in ventilation ducts to prevent the spread of fire/smoke.
