Specification text
Rectangular or square smoke control dampers to product standard EN 12101-8, tested to EN 1366-10 and EN 1366-2, for use in smoke extract systems. Smoke
control dampers are not only used for the exhaust of smoke, heat and combustion products, but also for the controlled removal of dangerous and toxic fire
suppression gases.
EK-JZ smoke control dampers can also be used in pressurisation systems and as pressure relief dampers in gas fire extinguishing systems. Also for extracting
smoke gases and for providing additional supply air for the natural or mechanical smoke extract to one or more fire compartments and in all listed systems of the
same type that need to fulfil modulation applications.
EK-JZ can be used in combined smoke exhaust systems which have been approved for controlled ventilation. The fire-resistant smoke control damper for multiple
compartments is suitable for installation in and on fire-resistant smoke extract ducts or smoke extract shafts and in fire-resistant standard supporting constructions. It
is controlled with open/close actuators that can be combined with control modules that are factory wired and fitted inside the temperature-resistant actuator
encasing.
