ISONE® 2.1 Fire Damper
Model: 11041323 | Type: ISONE®2.1 FTE70 Ø 500 mm
Product Overview & Features
The ISONE® 2.1 fire damper is designed for easy selection and installation across various partition types and fire resistance ratings. It is a key component for maintaining the fire integrity of building structures when penetrated by ventilation ducts.
Key Product Advantages
- Single damper model suitable for all partition types, simplifying selection.
- Ergonomic handle for rapid reset in just 2 seconds.
- Optional stainless steel axis for use in challenging environments.
- Optional remote control unit available (0.7m or 3m).
- Integration with the Aldes SecurONE application for data collection and sharing.
- Unique and simple mechanism, making it easy to choose, install, and maintain.
Operational Principle
The damper remains open in its standby position. It automatically closes to a safety position upon receiving a command from a Centralized Fire Management System (CMSI) or via a thermal probe. The damper can be reset remotely using its motorization.
Product Description
ISONE® 2.1 fire dampers are intended for tertiary buildings (public access buildings, high-rise buildings). They restore the fire resistance rating of partitions that are traversed by a ventilation duct. Standard configuration includes a thermal fuse with a 70°C default tripping point. Control is available via an electromagnetic coil (24/48 VDC emission, 24 VDC or 48 VDC break) and a 24-48 VDC reset motor. The fire rating achieved is up to 120 minutes for all common partition types.
Main Features & Specifications
- Certified and compliant with NF S 61937-5 and NF537 standards.
- CE marked according to EN 15650: 1812-CPR-1837.
- Standard C airtightness class according to EN 1751.
- Achieves EI 120 S -500 Pa rating on concrete walls/slabs, cellular concrete, type F plasterboard, and PROMAT/Geostaff remote mounting.
- Complies with EXAP EN 15882-2:2015, rules X.45 and X.46.
- Available in a diameter range from 100 mm to 900 mm.
Additional Features
- 100% upgradeable mechanism.
- Unique damper adaptable to all wall types.
- Installation on lightweight partitions with post-mounted lintel.
- Reset handle clearly indicates the damper's position.
- Features a large electrical connection box.
- Optional stainless steel axis for use in hostile environments.
- Optional remote control unit available.
- Contributes to low pressure drop in the ventilation system.
Installation
The ISONE® 2.1 damper can be installed without sealing on lightweight partitions, even with a post-mounted lintel. It supports recessed mounting on various materials including concrete walls/slabs, cellular concrete, plasterboard walls, and plasterboard type A (1h) and type F (2h). Remote mounting on PROMAT / GEOSTAF is also supported. Installation tabs facilitate positioning on lightweight partitions. Extended recess dimensions are specified by EXAP EN 15882-2:2015, rules X.45 and X.46. It is crucial to respect the fire classification reports during installation.
