Dampers
The category Dampers for Fire Barrier and Smoke Applications covers fire dampers, smoke dampers (leakage-rated dampers), combination fire and smoke dampers (fire and leakage-rated dampers), and corridor dampers.
For US applications, fire dampers are investigated in accordance with ANSI/UL 555, "Fire Dampers." Smoke dampers are investigated in accordance with ANSI/UL 555S, "Smoke Dampers." Combination fire and smoke dampers, and corridor dampers are investigated to the applicable requirements of both ANSI/UL 555 and ANSI/UL 555S. For Canadian applications, fire dampers are investigated in accordance with CAN/ULC-S112, "Standard Method of Fire Test of Fire-Damper Assemblies." Smoke dampers are investigated in accordance with CAN/ULC-S112.1, "Standard for Leakage Rated Dampers for Use in Smoke Control Systems." Combination fire and smoke dampers are investigated to the applicable requirements of both CAN/ULC-S112 and CAN/ULC-S112.1.
The category Ceiling Dampers covers dampers intended to function as a heat barrier in air-handling openings penetrating the ceiling membrane of fire-resistance-rated floor-ceiling and/or roof-ceiling designs for which they have been evaluated.
For US applications, ceiling damper are investigated in accordance with either ANSI/UL 555C, "Ceiling Dampers," or ANSI/UL 263, "Fire Tests of Building Construction and Materials." For Canadian applications, ceiling dampers are investigated in accordance with CAN/ULC-S112.2, "Standard Method of Fire Test of Ceiling Firestop Flap Assemblies" and/or CAN/ULC-S101, "Standard Methods of Fire Endurance Tests of Building Construction and Materials."
