201905 | User Manual S-SA2 & S-SA2L | 3/40 Introduction These are the original installation, inspection and operating instructions for the S-SA2 and S-SA2L smoke control dampers. EVERY S-SA2 AND S-SA2L SMOKE DAMPER NEEDS TO BE INSTALLED IN ACCORDANCE WITH THIS DOCUMENT! S-SA2 S-SA2L Rectangular smoke control damper without mesh for wall and ceiling installations. Rectangular smoke control damper with a mesh-fitted extension suited for vertical or horizontal duct installations.
/40 | User Manual S-SA2 & S-SA2L | 201905 Warnings Some damper parts may have sharp edges; therefore, to protect yourself, please use gloves during damper installation and manipulation. In order to prevent electric shock, fire or any other damage which could result from incorrect damper usage and operation, it is important to: 1. ensure that installation is performed by a trained person. 2. follow the written and depicted instructions provided within this User Manual closely. 3.
201905 | User Manual S-SA2 & S-SA2L | 5/40 Installation • The duct connected to the smoke damper must be supported or hung in such a way that the damper does not carry its weight. The damper must not support any part of the surrounding construction or wall which could cause damage and consequent damper failure. • The damper driving mechanism can be placed on either side of the wall, however, it needs to be situated to ensure easy access during inspection.
/40 | User Manual S-SA2 & S-SA2L | 201905 Installation Methods All S-SA2 and S-SA2L smoke dampers are CE certified according to EN 12101-8:2011, tested according to EN 1366–10 :2011+A1:2017, and classified according to EN 13501-4:2016. The smoke damper, together with its installation, form an inseparable part of the fire resistivity rating. Tab. 1: S-SA2 fire resistivity Certificate No.

Standard Distances Between Damper Bodies According to the EN 1366-2 standard, the minimum distance from the wall or ceiling to the damper body is 75 mm. For multiple crossings through a fire resistive wall, the minimum distance between two damper bodies is 200 mm. This applies for distances between the damper body and a nearby foreign object crossing the fire resistive wall. Damper clearances vary from the type of mechanism and their rotation (please see Fig. 3 and see Tab. 5).
201905 | User Manual S-SA2 & S-SA2L | 11/40 Wet Using Concrete Filling 1. The supporting construction opening must be prepared in a way depicted in the “Opening preparation” section (as per Fig. 1 – Fig. 2). Opening surfaces must be even and cleaned. The flexible wall opening must be reinforced as per the standards for plasterboard walls. The opening dimensions are driven by the nominal dimensions of the damper with added clearance. The opening will be made with dimensions W1 and H1 ( Fig. 4 ). 2.
