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.
Basic types of dampers square:
• MSD Cycling test with load (possible design .44, .54 a .66)
• MSD-W Cycling test without load (possible design .44, .54, .66, .4M0, .4M1, .5M0 a .5M1)
Basic types of dampers round:
• MSD Cycling test with load (possible design .44, .54 a .66)
• MSD-W Cycling test without load (possible design .4M0, .4M1, .5M0 a .5M1)
Dampers MSD can be open against flow and pressure.
Dampers MSD-W has to be open with the help of flow or without flow present.

Actuating mechanism
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
MSD (MSD-W) is equipped by actuating mechanism Belimo BLE24(BE24-12) for 24V supply or
BLE230(BE230-12) for 230V supply. MSD with big dimensions is equipped by actuating
mechanism Schischek InMax 50.75-S (dual supply 24V or 230V).
After being connected to power supply the actuating mechanism displaces the damper blade into
operation position "OPEN" or „CLOSED“ (according to method of connection, see connection
diagram). Running time is max. 60s. If is power supply cut off, actuating mechanism is stopped
in actual position. The crank handle supplied with the actuator allows it to be operated manually.
Signaling of the damper blade positions "OPEN" and "CLOSED" is provided by means of two
integrated, invariably set terminal switches.

Design with the communication and supply device
Design with the communication and supply device BKNE230-24 and the actuating mechanism
BLE24(BE24-12)-ST.
BKNE230-24 functions as a decentralized network device for supplying the actuating mechanism
BLE24(BE24-12)-ST on one hand and on the other hand it transmits signals from communication
and control device BKSE24-6.
It simplifies electrical wiring and interconnection of dampers. It facilitates on site check and
enables central control and checks of fire damper by means of a simple 2-conductor wiring.
BKNE230-24 signals the damper position „OPEN“/„CLOSED“ (from switches on the actuator)
and any fault alarms to the BKSE24-6 unit. It also receives positioning commands from the
control unit and triggers the actuator to the required position. The last control command is
retained troughout temporary power failures.
The BKNE230-24 unit monitors the positions of the switches on the actuator, its running time and
the exchange of data with the control and monitoring unit BKSE24-6. It also monitors the actuator
current and the power supply. In order to make installation as simple as possible the smoke
extraction damper actuators ...-ST are fitted with plug connectors that can be inserted directly into
the BKNE230-24 unit.
The 2-wire conductor must be connected to screw terminals 6 and 7. It is recommended that a
fire alarm signal cable suitable for the application be used for the 2-wire conductor. It is essential
to ensure the correct polarity. More information in catalogue Belimo.

Design with electric actuating mechanism with emergency function and electromagnet
MSD-W is always equipped by electric actuating mechanism BFN 230-T, BFN 24-T, DAF2.20S
or DAF1.20S (further only "actuating mechanism") and is complemented with initiation by means
of an electromagnet (solenoid). After being connected to power supply AC/DC 24V or 230V, the
actuating mechanism displaces the damper blade into operation position "CLOSED" and at the
same time it pre-stretches its back spring. When the actuating mechanism is under voltage, the
damper blade is in the position "CLOSED" and the back spring is pre-stretched. Time needed for
full closing of the flap blade from the position "OPEN" to the position "CLOSED" is maximum
60 sec. This possition is secured by initional lever. If the actuating power supply is cut off damper
is still in the position "CLOSED". After activation of electromagnet is released initiation lever and
the back spring displaces the damper blade into the breakdown position "OPEN". The time of
displacing the blade from the position "OPEN" to the position "CLOSED" takes maximum 16 sec.
In case that the power supply is restored again (the blade can be in any position), the actuating
mechanism starts to re-displace the damper blade into the position "CLOSED".
By voltage AC 230 V is damper equipped by electromagnet EM230. By voltage AC/DC 24 V is
damper equipped by electromagnet EM230 with pre-pulse switch SIEM24. SEIM24 activates the
electromagnet after capacitor charge witch is placed inside of SIEM24. It takes about 10 sec.
Charging time depends on the current supply. For reliable operation is necessary connect to
electromagnet or pre-pulse switch appropriate supply for 2 sec (230 V) or 20 to 30 sec (24 V).
