Product Description
Fire dampers designed for tertiary buildings (public access buildings, high-rise buildings). They restore the fire resistance rating of partitions traversed by a ventilation duct. Equipped with a default 70°C thermal fusible link. Controllable via a 24/48VDC normally open (NO) or 24VDC/48VDC normally closed (NC) electromagnetic coil. Reset motor operates on 24-48 VDC. Fire resistance rating up to 120 minutes on all standard partitions.

Principle of Operation
The damper is open in standby position. It opens upon command from the CMSI (Fire Safety Control System) or thermal probe, moving to the safety (closed) position. It can be reset remotely via the motorization.

Performance Curves
Diagram Description: Graphs illustrating performance characteristics. The first graph shows Pressure Drop (ΔP in Pa) versus Air Velocity (V in m/s) for various nominal damper diameters (ØD in mm). The second graph shows Acoustic Power Level (Lw in dB(A)) versus Air Velocity (V in m/s).
Installation Diagrams Description
The document includes diagrams illustrating the installation of the ISONE® 2.1 circular fire damper in various construction types:
- Concrete Wall/Slab: Shows the damper installed in a concrete wall or slab, requiring specific clearances (e.g., D+50 mm).
- Lightweight Plasterboard Partition (120 min): Illustrates installation in a 120-minute fire-rated plasterboard partition.
- Lightweight Partition with Post-Mounted Frame (60 min): Depicts installation in a 60-minute fire-rated lightweight partition using a post-mounted frame, showing required clearances (e.g., D+60 mm).
These diagrams specify required dimensions and mounting configurations for each application.
