CR120 - 1S European circular fire dampers surface-mounted for small diameters
Description
Circular surface-mounted fire dampers with a fire resistance up to 120 minutes. They ensure minimal pressure drop thanks to the thin blade, the thermal fuse aligned with the blade and the drive located outside the casing. Available in the version for small diameters (from 100 mm). The galvanised steel casing contributes to the damper's light weight. The fire dampers are CE marked with performance declared according to EN 15650:2010 and with fire resistance determined according to EN 1366-2 up to EI 120 (ve i ↔ o)S - (500Pa) and EI 120 (ho i ↔ o)S - (500Pa) depending on the installation surface. The dampers can be equipped with different types of mechanisms, depending on the specific needs of the project.

ONE RFT actuator characteristics
The microprocessor-controlled servomotor with spring return, ONE Rf-t, is designed to efficiently operate Rf-t fire dampers of any size.
The main characteristics of the ONE Rf-t actuator are the following:
• very low stand-by energy consumption (0.12 W) which allows for up to 5 times less energy consumption compared to conventional servomotors installed in fire dampers;
• the opening status of the fire damper is visible via an indicator located on the actuator; in addition to this, an LED indicates whether the device is powered;
• the main thermal activation device allows for operational tests to be performed even if there is no mains power supply;
• a further activation device is integrated in the actuator in order to detect a possible fire outside the duct;
• the fuse can be replaced quickly and easily. The fuse housing is located in the servomotor body and it can also be used as an inspection hole for an endoscopic camera;
• the damper can be reset manually using a common 9 Volt alkaline battery. Up to 50 reset cycles can be performed with a single battery;
• IP54 enclosure made of shock-resistant technical polymer.
• there is a pair of microswitches at the start and at the end. Both power and position cables are oversized and clearly identified.
• Power supply 24 VAC/VDC (-10/+20%) or 230 VAC (-15/+15%).

Minimum distance principle
This type of fire damper has been optimised to minimise the installation distance between two dampers and between the damper and the adjacent wall.
