  • TECHNICAL MANUAL

    Fire dampers that incorporate a fusible link (thermal device) are designed to close when triggered by the elevated temperatures within a duct in the event of fire. This precludes their use in Smoke Extract or Pressurisation systems as the dampers, once activated, would prevent these systems from fulfilling their intended function.
