Standards and guidelines

Construction Products Regulation
EN 12101-8 Smoke and heat control systems – Smoke control dampers
EN 1366-10 Fire resistance tests for service installations – Smoke control dampers
EN 13501-4 Fire classification of construction products and building elements using data from fire resistance tests

Maintenance

Smoke control dampers must be operational at all times and must be maintained regularly so that they meet the performance requirements.

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 of the smoke control damper 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.

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.

Quick sizing tables in the Easy Product Finder provide a good overview of the volume flow rates for different airflow velocities and the corresponding differential pressures
Exact values can be determined with the help of our design program EPF

Correction for different throttle positions

The adjustment of the damper blade angle enables the setting of different throttle positions.
Based on the determined data for the open position, both the resistance coefficient and the sound power level can be corrected to design the operating conditions with angled blades.
For this purpose, the resistance coefficient is multiplied by the correction factor C, which corresponds to the diagram of the "Resistance factor"
for the correction factor.
For the correction of the sound power level, this is added to the correction value K, which corresponds to the diagram of the "Sound power level"
for the correction value.
Smoke control dampers with a height of less than or greater than 320 mm are differentiated.

Example:
EK-JS / installation case A
H × B: 960 mm × 1000 mm
Upstream velocity: 5 m/s

EPF (data for OPEN position)

Resistance factor = 0.23
Sound power level = 40 dB(A)

Correction for a blade angle of 65
(read from diagram correction factor "resistance coefficient" and correction value "sound power level")

Resistance factor:
Correction value C = 20
0.23 × 20 = 4.6

Sound power level:
Correction value K = 8
40 dB(A) + 8 dB(A) = 48 dB(A)

Interfaces to higher level systems

TROX fire and smoke protection systems have standardised interfaces for central building management systems. In the simplest case, the interface consists of discrete signalling contacts that connect the alternating inputs and outputs of TROX systems and other building components.
