Manipulation of S-BM2
The S-BM2 is made of boards and can thus be considered fragile. Handling and manipulation must be done with care.
Smaller dimensions can be manipulated and placed in the installation opening by two persons. Bigger dimensions are
supplied with wooden blocks, those serve as support for suitable lifting equipment (forklift, crane).
Please follow both textual and graphic instructions (Fig. 4 up to Fig. 10):
1. Unpack the damper and place it in vertical position.
2. Remove grille and place the holder between the upper-most blade and the frame.
3. Carefully lift the smoke control damper with the forklift, crane.
4. Prepare the opening, damper hanger, connection surfaces and/or lling as per the desired installation type.
5. Place the smoke control damper in the opening (wall installation) or on the opening (duct installation).
6. Once the smoke control damper has been placed x the damper to ductwork:
a) For wall installation - insert the lling as per desired installation.
b) For duct installation – x the hangers so that the weight of the damper is supported.
7. Carefully remove the fork.
8. Remove the wooden support.
9. If the ductwork ends with the damper – install a grille or grilles.

inside the damper during installation to avoid any damage caused to the damper housing by the weight of the lling.
3. Fill in the area between the wall and the damper with gypsum plaster or mortar or concrete lling (3)
while paying attention to prevent the fouling of the damper’s functional parts, which could limit its correct
functionality. The best way is to cover the functional parts during installation.
To prevent seepage of the lling material, use of boards is recommended.
First, let the plaster or mortar or concrete lling harden and then perform the next steps.
4. After the lling hardens, remove the duct support from inside of the damper.
5. If needed, uncover and clean the damper after installation.
6. Check the functionality of the damper.

Installation in the Duct Made of Promatect Boards
S-BM2 smoke control damper can be installed on “single” (tested according to EN 1366-9) or “multi” (tested according
to EN 1366-8) ductwork. If mounted on a duct classied with lover re resistivity, the re resistivity of S-BM2 smoke
control damper will be decreased to the duct level. This section does not depict duct hanger rules as those are
dependent on the weight of the duct itself and must be statically approved. Smoke control dampers must be suspended
from solid ceiling slabs using adequately sized threaded rods. When using anchors in the ceiling, use re rated anchor
(with suitable re rating certicate). Suspension systems longer than 1,5 m require reresistant insulation.

S-BM2 smoke control damper can be installed on “single” (tested according to EN 1366-9) or “multi” (tested according
to EN 1366-8) ductwork. If mounted on a duct classied with lover re resistivity, the re resistivity of S-BM2 smoke
control damper will be decreased to the duct level. This section does not depict duct hanger rules as those are
dependent on the weight of the duct itself and must be statically approved. Smoke control dampers must be suspended
from solid ceiling slabs using adequately sized threaded rods. When using anchors in the ceiling, use re rated anchor
(with suitable re rating certicate). Suspension systems longer than 1,5 m require reresistant insulation.
IMPORTANT:
Flexible connection between duct and S-BM2 is needed, when connected to metal duct.
The suspension of the damper must be loaded only with the weight of the damper.
The interior of the S-BM2 smoke control damper must remain accessible for maintenance,
it may be necessary to create additional inspection panels in the connecting ducts.

After installation, it is necessary to adjust the damper into its operating position “closed”.
In case, that the damper is used for extraction of pollutants, adjust the damper into its operating position “open”.
Connect the actuator to the relevant electric power supply (
The electromotor is activated and adjusts the damper into its operating position.
Fig. 20 up to Fig. 23)
Smoke Control Damper Functionality Check
Switching the damper to the “open” position:
• The blade must come to the fully open position within 60 seconds and must remain locked.
• After reaching the end position of the blade, the appropriate signaling circuit must switch on
– wires S1 and S2 must be connected.
Switching damper to the “closed” position:
• The blade must come up to the fully closed position within 60 seconds and must remain locked.
• After reaching the end position of the blade, the appropriate signaling circuit must switch on
– wires S4 and S6 must be connected.
Smoke Control Damper Inspection
The actuator keeps the dampers on stand-by during their entire life cycle in accordance with this manual issued by
the manufacturer. It is not permitted to alter the dampers in any way or to perform any changes to their structure
without the manufacturer’s consent.
The operator performs regular checks of the dampers as per established regulations and standards at least once
every 3 months.
The check needs to be performed by an employee who has been specically trained for this purpose by the
manufacturer. The current damper condition evaluated during the inspection must be entered into the
Journal” along with the date of the inspection, the legible name, surname and signature of the employee who
performed the inspection. The Operating Journal includes a copy of the employee’s authorization. If any discrepancies
are discovered, these need to be entered in the Operating Journal along with a proposal for their removal.
The Operating Journal can be found
Immediately after the installation and activation of the damper, it must be checked under the identical conditions
as apply to the above mentioned 3-month inspections.
movement are checked. Due to the need to perform a visual check of the damper’s internal parts, it is possible
to dismount the grille, which will enable access inside the damper or open
the inspection lid installed in the duct close to the damper.
The damper’s internal casing, sealings, foaming substance, the damper blade condition and accuracy of its closure
during its leaning against the backstop in the closed position must all be checked. There must not be any strange
objects or a layer of impurities from the air distribution systems inside the damper.
