Product Overview
The ISONE® 2.1 fire dampers are designed for fire protection in ventilation systems, ensuring the integrity of fire-rated walls and floors. They are easy to select, with a single model suitable for all types of partitions and fire resistance ratings.
Key Product Features:
- Single damper model for all partitions: easy selection.
- Ergonomic quick reset handle: 2 seconds to reset.
- Stainless steel spindle option for demanding environments.
- Remote control box option (0.7 m or 3 m).
- ALDES SecurONE application for damper data collection and sharing.
- Unique mechanism, simple to complex: easy to choose, install, and maintain.
- Compatible with BELIMO 24/48 Vcc actuators with MODBUS modules.
- The damper is open in standby position.
- It opens upon command from the Fire Safety System (CMSI) or thermal probe, moving to the safety (closed) position.
- It can be reset remotely via the motorization.
Product Description
Fire dampers intended for commercial buildings (ERP, IGH). They restore the fire resistance rating of partitions traversed by a ventilation duct.
- Equipped with a thermal fusible link (70°C default).
- Can be controlled by a fail-safe solenoid coil (24/48Vdc) or fail-secure solenoid coil (24/48Vdc).
- 24/48V reset motor.
- Fire resistance rating up to 120 minutes for all standard partitions.
Application Areas
