FKRS-EU

In case of a fire, fire dampers shut automatically to prevent the propagation of fire and smoke through ductwork to adjacent designated fire compartments. Type FKRS-EU fire dampers are tested to EN 1366-2 and comply with EN 13650. 
Local requirements and building inspectorate approvals are essential in the country where the units are to be installed.

Correct approved installation locations are in solid walls and ceiling slabs, on the face of solid walls, in lightweight partition walls, in lightweight fire walls, and in shaft walls. 
Installation in horizontal and vertical ducts. Air flow direction is not critical. 
In case of a fire, the damper is triggered at 72 °C or 95 °C (for use in warm air ventilation) either by a fusible link or thermoelectrically with a spring return actuator. The release mechanism is accessible and can be tested from the outside. 
The fire dampers have an inspection panel.

The class of performance of FKRS-EU fire dampers is up to EI 120 (v_e, h_o i↔o) S according to EN 13501-3 and depends on the application.
