EK-JS

Specification text

Type EK-JS smoke control dampers are tested according to EN12101-8 and EN 1366-10. In rectangular steel and stainless steel construction. Intended for the discharge of smoke and heat in smoke extract systems and for the flow of necessary supply air into the area from which smoke is to be extracted. EK-JS is intended for use in pressurised ventilation systems (DBA) in order to keep safety stairwells and their anterooms and fire brigade lift shafts or escape tunnels smoke-free. They thus enable the controlled discharge of released smoke. EK-JS is intended for use in single sections and may be used at elevated operating temperatures of up to 600 °C on and in horizontally and vertically aligned smoke extract ducts according to EN 12101-7, tested according to EN 1366-9. EK-JS can be used in combined systems (combination damper) for ventilation and is suitable for restricting extract air volume flows. The OPEN-CLOSE actuators can be signalled either with ready-wired actuator control modules or with bus modules.
