1. Description
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 ventila-
tion system opens the damper in the aected 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
E600 120 (ve- i↔o) S1500CmodMAsingle.
1.1 Damper Characteristics
• CE certified acc. to EN 12101-8
• Tested in accordance with EN 1366-10
• Classified acc. to EN 13501-4+A1
• External Casing leakage min. class B, Internal leakage min. class 3 acc. to EN 1751
• Cycling test in class Cmod acc. to EN 12101-8
• ES Certificate No. 1391-CPR-2020/0187
• Declaration of Perfomance No. PM/SEDS-L/01/22/1
• Hygienic assessment of smoke control dampers - Report No. 1.6/pos/19/19c
1.2 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 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 60 721-3-3. Temperature in the place of installation
is permitted to range from -30°C to +50°C.
2. Design
2.1 Design with Actuating Mechanism
Design .44 and .54
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 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.
Design .65
Belimo modulating actuators, BEN (BEE)-SR series for 24V AC/DC
are specially designed for remote control of smoke control dampers.
The position of the damper blade is adjustable by means of control
voltage 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 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.

Example, how to calculate eective area and size of
SEDS-L damper, when knowing air volume in (m³/s)
or (m³/h) on damper. Maximum allowed air velocity on
SEDS-L is 12 (m/s).
Q - air volume (m3/s)
Sef - eective free area of damper (m2)
v - air velocity on damper (m/s)
Example:
Air volume needed is 26 000 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 tab. 7. The effective area has
to be the same or bigger. There will be more options
of damper, sizes A×B.
Sef = Q / v

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.
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.
Spare parts are supplied only on basis of an order.

6. Placement and Assembly
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.

8. Inspection and Testing
The appliance is constructed and preset by the manufacturer, its operation is dependent on proper installation
and adjustment.
9. Transportation and Storage
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.
10. Assembly, Attendance, Maintenance and Revisions
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 smoke control
dampers must be done according international and local norms and laws.
All eective 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.
Manual operation
Without power supply, the damper can be operated manually and fixed in any required position.
10.1 Electrical Connection of the Actuator in Protection Box
Protection Box Without Slot of Predrilled Holes
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.
• Use drill (drill size acc. To suit connecting cable Ø + 2 mm for seal up by mastic) and make two holes
(see fig. 14). It is possible to drill holes in any side of the housing.
• 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.
