Multi smoke dampers are shutters in the smoke exhaust duct systems. The dampers are
designed to remove heat and combustible products (e.g. smoke) from effected fire compartments.
In the event of fire the Smoke and Fire ventilation system opens the damper in the affected
section and removes combustion products and heat from this section.
The damper blade is controlled by electrical actuating mechanism.
Dampers are fire resistant and are intended for systems with automatic activation.
Dampers can be installed in construction of the fire compartment.

Working conditions
Exact damper function is provided under the following conditions:
a) maximum air velocity 15 m/s
b) underpressure max. -1500 Pa or overpressure max. 500 Pa.
Dampers can be installed in arbitrary position (horizontal or vertical blade axis).
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.
Design with actuating mechanism
Belimo actuators are used for dampers, series BEN, BEE, BE for 230V AC resp. 24 V AC/DC,
Schischek InMax 50.75-S actuators (universal 24V or 230V supply) are used for large size of
dampers.
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 can be 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.
Actuating mechanism
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 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.

BKNE 230-24
Actuating mechanism
Design with the communication and 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 can be 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.
This variant is not available for dampers with Schischek InMax 50.75-S actuator.

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).

are specified in the Tab. 3.2.1.
Values "c" and "a" has to be respected when projecting related smoke exhaust ducts.
For the design .66 (with BKNE supply and communication device) add to weight of the damper
with an actuating mechanism (from the Tab. 3.2.1.) the weight of BKNE (0.7 kg).
Dampers can be supplied on the customer´s demands in all subdimension of the above men-
tioned range.
Flanges of dampers are 30 mm wide with oval hole.

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 EN 1366-9 or can be
installed in the construction of the fire compartment.
Dampers can be installed with the actuator on the top, bottom* or either side.
* if Actuator is installed on the bottom take care when removing the actuator housing cover.
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.
The distance between damper:
- distance 200 mm between dampers installed in the duct;
- distance 75 mm between damper and construction (wall/ceiling).
"Wall edge sticker" indicates the recommended edge of installation of fire damper into the fire partition structure (wall).
The damper must be installed so that the entire damper blade - in the closed position - is located inside the fire separating structure
(wall) and at the same time the control mechanism and inspection openings are freely accessible.

This is the EN 1366-10 test standard distances. They are
considered as minimum. Actual location should be based
on wall manufacturers requirements.
For lightweight walls always consult the wall manufacturer
specific guidelines for penetrations sizes and distances.
