Smoke extraction dampers - single are shutters in smoke exhaust piping systems. Dampers are
designed to remove heat and combustion products (e.g. smoke) from single fire compartment.
In the event of fire the Smoke and Fire ventilation system opens the damper in the affected
section which removes combustion products and heat from this section.
The damper blade is operated by an actuating mechanism.
The dampers can be installed in various duct sizes with respect to the field of direct applications
according with EN 1366-9.
The field of direct applications based on tests results is acceptable according to EN 1363-1,
part A.1 and A.2, EN 1366-2, part 13 and EN 1366-10, part 9.
Smoke extraction dampers - single are classified as
The duct can be ended by KMM (TPM 002/96) grilles.

Working conditions
Dampers are designed for smoke exhaust piping systems with underpressure max. 1500 Pa or
overpressure max. 500 Pa.
Dampers are designed for maximum air velocity 12 m.s.
Dampers are installed with the horizontal or vertical axis of the blades.
Dampers are intended for installation on air ducts and in/onto the walls where in the case of wall
installation, this wall with damper does not have fire resistance and therefore does not separate
two fire compartments.
Dampers are suitable for systems without abrasive, chemical and adhesive particles.
Dampers are designed for macroclimatic areas with mild climate according to EN 60 72133.
Temperature in the place of installation is permitted to range from - 20°C to + 50°C.
Design with actuating mechanism
SEDS-L is equipped by actuating mechanism Belimo BLE24 (BE24-12) for 24V supply or
BLE230 (BE230-12) for 230V supply. After being connected to power supply the actuating
mechanism displaces the damper blade into operation position "OPEN" or „CLOSED“ (according
to method of connection, see connection diagram). Running time is max. 60s. If is power supply
cut off, actuating mechanism is stopped in actual position. The crank handle supplied with the
actuator allows it to be operated manually. Signaling of the damper blade positions "OPEN" and
"CLOSED" is provided by means of two integrated, invariably set terminal switches.

Design with the communication and power supply unit
Design with the communication and power supply unit BKNE230-24 and the actuating mechanism
BLE24(BE24-12)-ST.
BKNE230-24 functions as a decentralized network device for supplying the actuating mechanism
BLE24(BE24-12)-ST on one hand and on the other hand it transmits signals from communication
and control device BKSE24-6.
It simplifies electrical wiring and interconnection of dampers. It facilitates on site check and
enables central control and checks of fire damper by means of a simple 2-conductor wiring.
BKNE230-24 signals the damper position „OPEN“/„CLOSED“ (from switches on the actuator)
and any fault alarms to the BKSE24-6 unit. It also receives positioning commands from the
control unit and triggers the actuator to the required position. The last control command is
retained troughout temporary power failures.
The BKNE230-24 unit monitors the positions of the switches on the actuator, its running time and
the exchange of data with the control and monitoring unit BKSE24-6. It also monitors the actuator
current and the power supply. In order to make installation as simple as possible the smoke
extraction damper actuators ...-ST are fitted with plug connectors that can be inserted directly into
the BKNE230-24 unit.
The 2-wire conductor must be connected to screw terminals 6 and 7. It is recommended that a
fire alarm signal cable suitable for the application be used for the 2-wire conductor. It is essential
to ensure the correct polarity.

BKSE24-6 indicates operating status and fault signals for the smoke extraction dampers. The
auxiliary contacts that are incorporated also allow functions to be signaled or passed on to
higherlevel control systems. The signals from the BKNE230-24 unit are received by the
BKSE24-6 unit and evaluated individually. All BKNE230-24 units are triggered simultaneously.
To BKSE24-6 can be connected max. 6 BKNE230-24.
Communication is via the 2-wire conductor. Correct operation of the dampers is indicated by
means of two LEDs. The operating status of the SBSE-Control system and any faults are also
indicated by this LED and the corresponding fault LED.
The BKSE24-6 unit can be clipped directly to a 35 mm DIN mounting rail and connected by
means of two 9-pole plug-in terminals. The BKSE24-6 unit isn´t in the scope of delivery MANDIK

Smoke extraction dampers single are designed to remove heat and combustion products (e.g.
smoke) from single fire compartment according EN1366-9.
Smoke extraction dampers single are designed for installation with horizontal or vertical axis of the blades.
Backtoback smoke exhaust duct has to be hung or supported so as all load transfer from the backtoback
smoke exhaust duct to the damper is absolutely excluded. To provide needed
access space to the control device, all other objects must be situated at least 350 mm from the
control parts of the damper.
During installation the damper blade must be in position CLOSED. The damper body should
not be deformed in the course of installation. Once the damper built in, its blade should not grind
on the damper body during opening or closing.
Example, how to calculate effective area and size of SEDS-L damper [AxB], when knowing air volume in [m³/s] or [m³/h] on damper.
Maximum allowed air velocity on SEDS-L is 12 [m/s].
Formula:
Q … air volume [m³/s]
Sef … effective free area of damper [m²]
v … air velocity on damper [m/s]
Example:
Air volume needed is 26000 m³/h
26000 / 3600 = 7,222 m³/s
7,222 / 12 = 0,602 m² is min. effective free area [Sef]
Find the value Sef in the table 3.2.1. The effective are has to be the same or bigger. There will be more options of damper, sizes AxB.

Damper casing and damper blade are made of galvanized plate without any other surface finish.
Fasteners are galvanized.
The appliance is constructed and preset by the manufacturer, its operation is dependent on
proper installation and adjustment.
Dampers are transported by box freight vehicles without direct weather impact, there must not
occur any shocks and ambient temperature must not exceed + 40 °C. Dampers must be protected
against mechanic damages when transported and manipulated. During transportation, the
damper blade must be in the "CLOSED" position.
Dampers are stored indoor in environment without any aggressive vapours, gases or dust. Indoor
temperature must be in the range from -5 °C to +40 °C and maximum relative humidity 80 %.
Dampers must be protected against mechanic damages when transported and manipulated.
All effective safety standards and directives must be observed during damper assembly.
To ensure reliable smoke exhaust damper function it is necessary to avoid blocking the closing
mechanism and contact surfaces with collected dust, fibre and sticky materials and solvents.
Without power supply, the damper can be operated manually and fixed in any required position.
The actuator cover is made of fire-resistant material (fire protection board)
Assembly, maintenance and damper function check can be done only by qualified and trained
person, i.e. “AUTHORIZED PERSON” according to the manufacturer documentation. All works
done on the fire dampers must be done according international and local norms and laws.

15
Check of damper blade displacement can be realize after actuating mechanism supply connec-
tion or signal connection from higher level control systems. Blade displacement from position
“OPEN” to position “CLOSED” and return displacement is checked.
Before entering the dampers into operation after assembly and after sequential revisions, checks
and functionality tests of all designs including operation of the electrical components must be
successfully provided and finished. After entering into operation, these revisions must be done
according to requirement set by national regulations.
