Maintenance

Smoke control dampers must be operational at all times and must be maintained regularly such that they provide the required function.

Maintenance is required at least every 6 months
A maintenance report must be created; documents must be kept for reference
The functional reliability of the smoke control damper must be tested at least every six months; this has to be arranged by the owner of the smoke extract system; functional tests must be carried out in compliance with the basic maintenance principles stated in EN 13306 and DIN 31051. If two consecutive tests, one 6 months after the other, are successful, the next test can be conducted one year later
Depending on where dampers are installed, country-specific regulations may apply.
For details on maintenance and inspection refer to the installation and operating manual

Functional description

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 dampers are made of calcium silicate panels and are opened by an encased actuator; when smoke is detected, the actuator is triggered by a signal either from a duct smoke detector or from a fire alarm 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 safe position is 'open', the free area must be maintained even in the event of a fire.

The blades of EK-JZ move to the defined safe position upon receiving an automatically or manually triggered control signal. According to the specified time-temperature curve, an EK-JZ can still fully open or close after 25 minutes (MA, manual release).

Regular maintenance of the smoke control damper is required to ensure its functional reliability.

EK-JZ/500×830, A_free = 0.31 m², Δp_t = 3 Pa

Correction factor for A_free up to 0.37 m²: 3.99

Total differential pressure for a smoke control damper with cover grille: Δp_t = 3 Pa × 3.99 = 12 Pa

EK-JZ/400×1030, A_free = 0.32 m², Δp_t = 3 Pa

Correction factor for A_free up to 0.37 m²: 3.99

Total differential pressure for a smoke control damper with cover grille: Δp_t = 3 Pa × 3.99 = 12 Pa

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 to one or more fire compartments.

EK-JZ can be used in combined smoke extract 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 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.

F, A, B, C, D, E, G, H – Connecting subframes and cover grilles

Application

A connecting subframe (F) is required for sheet steel smoke extract ducts
Cover grilles are attached to the damper or to the end of ducts; this application has been approved based on a fire test to EN 1366-10
The cover grille free area is approx. 80% for crimped wire mesh (A) and approx. 70% for perforated metal plates
Cover grille variants C, D, E, G, H cover the blades of EK-JZ but not the actuator encasing
If you order a cover grille separately, you may choose a size that covers the damper blades and the actuator encasing and fix the grille along the perimeter of the shaft wall
Connecting subframes and cover grilles are factory mounted to the dampers
Connecting subframes and cover grilles may also be ordered separately

Correct use, Installation details, Basic information and nomenclature

Design information

Approved for use in mechanical smoke extract systems
For use in pressurisation systems
For use in natural smoke and heat exhaust systems
For heat exhaust purposes
A cover grille is required either on the damper or at the end of the smoke extract duct
If the damper is installed in a solid shaft wall, on a fire-resistant smoke extract duct or in a fire-resistant smoke extract duct with a lower fire resistance class than that of the smoke control damper, the fire resistance class of the shaft wall applies also to the EK-JZ (details upon request)
Fire-resistant smoke extract ducts must be installed in such a manner that they do not impose any significant loads on the smoke control damper in the event of a fire
Sheet steel smoke extract ducts to EN 1366-9 must be connected with flexible connectors according to the manufacturer's instructions for the sheet steel ducts
Smoke control dampers must be installed, connected and attached according to the operating and installation manual

Declaration of performance and installation and operating manual

For details on the correct use and on the performance level, refer to the declaration of performance
The correct installation of the smoke control damper is described in the installation and operating manual
Both documents are available for download on our website

Installation and commissioning

Installation on/in concrete or masonry shaft walls
Installation in or on tested, fire-resistant vertical or horizontal smoke extract ducts
Installation in fire-resistant REI 90 or EI 90 walls
For smoke extract ducts made of calcium silicate from 35 mm wall thickness
After installation the damper must remain accessible for inspection, cleaning and repair
Connected smoke extract ducts must have an inspection access
Mechanical smoke extract systems require that the power supply is maintained even in the event of a fire

Smoke control dampers must be installed, connected and attached according to the operating and installation manual
