Smoke and heat extraction dampers - multi are closures in the ductwork of smoke extraction
devices. In the event of a fire, the smoke and heat removal system open the dampers in the
affected section, therefore enabling the extraction fans to remove combustion products and heat
from the endangered areas.
The damper slat is controlled by an actuator.
The damper is fire resistant and is designed for systems with automatic or manual activation.
Smoke dampers are intended for use in spaces with multiple fire compartments, which can be
connected by a smoke extraction duct tested according to EN 1366-8 or can be installed in the
construction of the fire compartment.
The dampers can be supplied with flange(s) or without flange(s), with cover grille(s).
Flanges and grilles are not installed on the damper, they are included loosen. Flanges are
required to fit the cover grilles. Grills and flanges must be installed to the dampers only after
installation of the damper into the wall.
In normal operation, the SEDM-L dampers remain closed. If necessary, in the event of a fire, the
SEDM-L dampers in the affected fire section will open completely so that the smoke can be
removed. When the smoke and heat removal dampers are activated, the dampers used for air
supply in the affected section open. The dampers used to supply air in the affected fire section
are installed at the ground. The dampers are controlled from the central control system on the
basis of signals, e.g. from smoke detectors. The use of cables with a certain fire resistance for the
supply voltage ensures that the actuator is supplied even in the event of a fire.
During ventilation, SEDM-L dampers in the smoke and heat extraction system are controlled by
a control system, it's possible to fully open, close or continuously control the flow. The SEDM-L
dampers, which are used for air supply, remain closed during ventilation.

The damper's faultless operation is ensured under the following conditions:
a) maximum air flow speed 12 m/s
b) maximum vacuum up to 1000 Pa or overpressure up to 500 Pa
The dampers are suitable for installing in a vertical position, with the slat axis horizontal.
The dampers are designed for environments protected against weather conditions with class 3K5
climatic conditions, without condensation, icing, ice formation, without water and from sources
other than rain and with a temperature limit of -30°C to 50°C.

Belimo actuators are used for dampers, series BEN, BEE, BE for 230V AC resp. 24 V AC/DC.
After connection to the power supply voltage, the actuator moves the damper slats 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
slats positions is ensured by two built-in fixed “potential-free” end- limit switches.
The actuator for operating the damper slats 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 (BEE)-SR series for 24V AC/DC are specially designed for remote control
of fire dampers. The position of the damper slats is adjustable by means of control voltage 0 (2)...10V DC.
The signalling of the "OPEN" and "CLOSED" damper slats positions is ensured by two built-in fixed
“potential-free” limit switches.
The actuator for operating the damper slats is mounted in an insulated cover/box. It is accessible after
removing the cover lid. The electrical connection of the actuator is made with non-flammable 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 power cables of the actuator. The cable entry must
meet a minimum fire resistance of 30 minutes.

10 Communication and power supply device BKNE 230-24
Design with communication and power supply device BKNE 230-24 and with actuator BEN (BEE, BE)-ST for 24V.
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.

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).

●They're designed for installation in smoke and heat removal duct according to EN1366-8.
●They're suitable for installation in a vertical position, with the slat axis horizontal.
●Dampers and duct must be suspended separately. The connected piping must be suspended in such
a way that the transfer of all loads from the adjoining ventilation duct to the damper body is completely
excluded. Adjacent duct must be suspended or supported, as required by the duct suppliers.
●o provide the necessary space for access to the control device, it is recommended that other objects
be at least 350 mm away from the control parts of the damper.
●Transport the damper to the installation site in the transport packaging. Pay attention to the appropriate
length of the forks of the forklift /handling equipment/ to avoid breaking of wooden planks, consequently
damaging the damper´s slats.
●Smaller dimensions can be transported, handled and installed into the mounting hole manually, for
dimensions where a handling insert is included in the delivery, it is recommended to use a suitable
handling tools and machines, eg. a forklift.
