Description
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 aected 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).
Smoke and heat removal system
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 aected 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 aected section open. The dampers used to supply air in the aected 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.
Ventilation system
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.

In practice, the dampers are never open when there is a risk of smoke.
Operating conditions
Trouble-free operation of the dampers is guaranteed under the following conditions:
• maximum air flow speed 12 m/s
• maximum vacuum up to 1000 Pa or overpressure up to 500 Pa
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.

Design
1. SEDM-L Smoke Extraction Damper / MULTI Designs
1.1 Design with actuating mechanism, Design .44 and .54
Belimo actuators are used for dampers:
BLE 24 (BE 24-12), resp. 24 V
BLE 230 (BE 230-12), resp. 230 V
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.
5
Belimo actuators are used for dampers: BLE 24 (BE 24-12) for 24V
BLE 230 (BE 230-12) for 230V
After connection to the supply voltage, the actuator moves the damper slat to the "OPEN" or
"CLOSED" position (according to the corresponding connection, see wiring diagram). The
adjustment speed is max. 60 s. If the power supply is interrupted, the actuator stops at the current
position. The damper can be operated manually, after removing the cover with a special handle,
which is included with the actuator. Signalling for "OPEN" and "CLOSED" damper slat positions
is ensured by two built-in fixed limit switches.
The actuator for operating the damper slat, including the mechanical control mechanism (or the
communication and network device BKNE 230-24) is mounted in an insulated housing. The
actuator, control mechanism (or communication and network device BKNE 230-24) is accessible
after removing the side cover. The actuator's electrical connection (or communication and
network device BKNE 230-24) is made with a non-flammable cable (or a cable located in the
adjoining cable duct), which passes through an opening made in the housing wall of when
connecting the actuator power cable. This penetration must be equipped with a cable penetration
with a minimum fire resistance of 30 minutes.

3. Placement and assembly
3.1 Multi-slat smoke and heat dampers - multi SEDM-L
• 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.
• 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.
3.2 Transport to the installation site
• 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.
3. Drive the forklift under the highest slat. It´s necessary to put a board between the slat and the fork along
the slat´s entire length so that the slat is not damaged when the damper is raised.
3.3 Damper handling when installed in the mounting hole
1. Place the damper in a vertical position. Do not remove the transport pacers and corners!.

Installation of multiple dampers in a fire diving structure
• Minimum distance 200 mm between dampers installed in one fire dividing structure.
• Distance 75 mm between the damper and the structure (wall/ceiling).
• When installing SEDM-L (smaller dimensions), which is not equipped with transport spacers and corners,
the sheets must be in the “CLOSED” position. The damper body must not be deformed during installation.
• After installing the damper, the damper slats must not be opened, or closing on the damper body.
