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.
Round smoke extraction dampers only for duct installation - single are classified as
↔
The duct can be ended by KMM (TPM 002/96) grilles. During grilles installation blade overlaps
has to be respected see chapter 3.3.

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 15 m/s.
Dampers are designed for installation with horizontal blade axis. Flow direction has to be led from
actuating side (it is labeled by arrow on the damper casing).
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 -30°C to +50°C.
Design with actuating mechanism
Belimo actuators are used for dampers, series BEN for 230V AC resp. 24 V AC/DC.
After connection to the power supply voltage, the actuator moves the damper blade to the
"OPEN" position or "CLOSED" (according to the corresponding connection, see wiring diagram).
If the power supply is interrupted, the actuator stops at the current position. The signalling of the
"OPEN" and "CLOSED" damper blade positions is ensured by two built-in fixed “potential-free”
end- limit switches.
The actuator for operating the damper blade is mounted in an insulated cover/box. It is accessible
after removing the cover lid. The electrical connection of the actuator is made with a non-
flammable cable (or a cable located in the adjoining cable duct), which passes through an
opening made in the wall of the insulated cover/box when installing the damper or when
connecting the actuator power cable. The cable entry must meet a minimum fire resistance of 30
minutes.
Belimo modulating actuators, BEN-SR series for 24V AC/DC are specially designed for remote
control of fire dampers. The position of the damper blade is adjustable by means of control volt-
age 0 (2)...10V DC.
The signalling of the "OPEN" and "CLOSED" damper blade positions is ensured by two built-in
fixed “potential-free” limit switches.
The actuator for operating the damper blade is mounted in an insulated cover/box. It is accessi-
ble after removing the cover lid. The electrical connection of the actuator is made with non-flam-
mable cables (or cables located in the adjoining cable duct), which pass through an opening
made in the wall of the insulated cover when installing the damper or when connecting the pow-
er cables of the actuator. The cable entry must meet a minimum fire resistance of 30 minutes.

Design with the communication and power supply unit
Design with communication and power supply device BKNE 230-24 and with actuator BEN 24-ST.
The BKNE 230-24 serves on the one hand as a decentralized network device for powering the
actuator and on the other hand transmits the signal of the communication and control device
BKSE 24-6.
It simplifies electrical installation and connection of dampers. In the meantime, it facilitates “on-site
inspection” and allows central control and inspection of dampers using a simple 2-wire line.
The BKNE 230-24 transmits the "OPEN" / "CLOSED" damper position (switches in the actuator)
and fault messages to the BKSE 24-6. It also receives commands from the control device and
controls the adjustment of the actuator to the desired position. The last control command will be
retained even after a temporary network failure..
The BKNE 230-24 controls the switching position of the actuator, its adjustment time and the data
exchange with the BKSE 24-6. In addition, it controls the actuator current (actuator connection) and
the power supply.
To simplify the connection, the actuator is equipped with plug connectors that plug directly into the
BKNE 230-24.
The actuator, communication and power supply device BKNE 230-24 are mounted in an insulated
cover, they are accessible after removing the cover. The electrical connection of the actuator and
the BKNE 230-24 communication and power supply device is made with a non-flammable cable
(or a cable located in an adjoining cable duct), the two-wire BKNE 230-24 cable should be
connected to terminals 6 and 7. It is also recommended to use cable, which is used for fire
signalling network. The cables pass through an opening made in the wall of the insulated cover
when installing the damper or when connecting the actuator power cable. The cable entry must
meet a minimum fire resistance of 30 minutes.
For more information on actuators and devices, see the Belimo catalogue.

Communication and control devices
indicates operating condition and faults of flue dampers. These conditions can be
signalled or transmitted to the higher-level control system via the auxiliary built-in contacts.
Signals from individual BKNE 230-24 are evaluated separately. All BKNE 230-24 are controlled
simultaneously. A maximum of 6 BKNE 230-24 can be connected to the BKSE 24-6.
Damper control is ensured with a simple 2-wire line. The damper's correct function is indicated by
two LEDs. The operating status of the entire control system and any errors are indicated by these
LEDs and the corresponding error LED.
Mounting and connection of BKSE 24-6 can be done on a 35mm DIN rail. It's connected using
two 9-pin terminal blocks (plug connectors).

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 blade axis.
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.
For damper (Fig. 10) the open damper blade overlaps the damper body from dimension D=315
by the value “a” or “a” and “c”. These values are specified in the Tab. 3.2.1.
Values "a" and "c" has to be respected when projecting related smoke exhaust ducts.

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 -30°C to +40°C and maximum relative humidity 95 %
(avoid condensation on the damper body). Dampers must be protected against mechanic
damages when transported and manipulated.
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.
All effective safety standards and directives must be observed during damper assembly.
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.

16
Use drill (drill size acc. To suit connecting cable Ø + 2 mm for seal up by mastic) and make two holes (see
fig. 13).
●Pull the heat resistant cable through the calcium silicate plate (wall) and connect with cables from actuator
acc. to above mentioned electrical diagram.
●Seal up the space around cable with fire resistant mastic (HILTI CFS-S ACR, PROMASTOP) or equivalent.
●Let the mastic harden.
Drill two holes into the protection box (from outside to inside) and pull through field wiring cables (fire
resistant cables) to connect actuator trailing lead. Protection box is made of calcium silicate plates.

17
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.
Spare parts are supplied only on basis of an order.
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.
In case that dampers are found unable to serve for their function for any cause, it must be clearly
marked. The operator is obliged to ensure that the damper is put into condition in which it is ready
for function and meanwhile he is obliged to provide the fire protection by another appropriate way.
Results of regular checks, imperfections found and all-important facts connected with the damper
function must be recorded in the "FIRE BOOK" and immediately reported to the operator.
Before entering the dampers into operation after their assembly and by sequential checks, the
following checks must be carried out for all designs.
Visual inspection of proper damper integration, inside damper area, damper blade, contact
surfaces and silicon sealing.
