Maintenance
Smoke control dampers must be operational at all times and regularly maintained. For this purpose, the required services must be provided.
Smoke control dampers are used in mechanical smoke extract systems. They are used for extracting smoke gases and for providing additional supply air to one or more fire compartments. The smoke control dampers are made of calcium silicate panels. In case of fire, the smoke control dampers are opened by a thermally encased actuator. Smoke detection is carried out by a duct smoke detector or via a fire alarm control system. Smoke control dampers have two safe positions: open and closed. In the case of fire-resistant smoke control dampers for multiple compartments, the safe position is either 'open' or 'closed', depending on the fire site and the path of the smoke to be extracted. If the position is 'open', the free cross-sectional area must be maintained even in the event of a fire. The smoke control damper moves to the desired safety position after receiving an automatic or manual control signal. A change in position is possible up to 25 minutes at a temperature load in accordance with the ISO standard fire curve (MA, manual release). In addition, the EK-JZ product series enables position changes for modulation applications (Cmod) and thus a pneumatic balancing in the venting mode of a combined system. This is done by moving the damper blades to intermediate positions. Regular maintenance of the smoke control damper is required to ensure its functional reliability.

* Data applies to uniform upstream and downstream conditions for smoke control dampers
Rectangular or square smoke control dampers acc. to product standard EN 12101-8, tested acc. to EN 1366-10 and EN 1366-2, for use in smoke extract systems. In addition to removing smoke, heat and combustion products from a fire compartment, smoke control dampers enable the controlled removal of released hazardous and toxic combustion and fire suppression gases. The EK-JZ smoke control dampers can also be used in pressurised ventilation systems and venting devices of overpressure systems as well as pressure relief dampers for gas extinguishing systems. Also for extracting smoke gases and for providing additional supply air for the mechanical smoke extract of 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. The OPEN-CLOSE actuators can be controlled either with ready-wired actuator control modules or bus modules inside the temperature-resistant actuator encasing.
