Description
S-RA1 smoke control dampers operate with mechanical or natural smoke and heat extraction systems. They remove
poisonous gases, smoke and fire and can also supply clean air to fire compartments.
S-RA1 dampers have an actuator without a spring. Thus, they have two safety positions: an “open” position and a
“closed” one. Power is necessary for the smoke control dampers.
The “Installation Methods” section shows the types of installations that are permitted.
Special Properties
• The pressure level is 2 (-1000 Pa ... 300 Pa).
• The casing leakage class C (compliant with EN 1751).
• The blade leakage class 3 (compliant with EN 1751).
Fire Resistivity
S-RA1 smoke control dampers have a CE certification that meets the EU’s Construction Products Regulation and
complies with Standard EN 12101-8:2011. EN 1366-10:2011 + A1:2017, and EN 1366-2:2015 are the reference
Standards for the tests. EN 13501-4:2016 is the reference Standard for the Classification.
Resistivity rating for damper installed on the duct: E600 120 (ved - i↔o) S1000 Cmod AAsingle
Types of Activation
•B230 - Smoke control damper with an activation mechanism with a Belimo actuator (230V AC) and auxiliary
switches.
•B24 - Smoke control damper with an activation mechanism with a Belimo actuator (24V AC/DC) and auxiliary
switches.
•B24-W - Smoke control damper with an activation mechanism with a Belimo actuator (24V AC/DC) and auxiliary
switches, with provided cable connectors for the supply and communication unit (communication unit not part of the
mechanism).
•B24-SR - Smoke control damper with an activation mechanism with a modulating Belimo actuator (24V AC/DC; 0(2)
V...10 V DC) and auxiliary switches. Modulating actuators have the possibility to open the blade at a desired angle.
•BST0 - Smoke control damper with an activation mechanism with a Belimo actuator (AC/DC 24 V, supply through
communication unit: AC 230 V) and with a Belimo supply and communication unit BKNE230-24 (other
communication units on demand).

Design
The casing and the blade of the S-RA1 are made of a galvanized sheet metal. A rubber seal prevents leaks of heat or
smoke. The casing has connections on two sides with a rubber seal to attach to duct with nominal internal dimension.
The dampers actuator of the S-RA1 is always accessible.
Composition of Materials
The product contains these materials:
• galvanized sheet metal
• rubber
• PE tapes and foil
• galvanized steel fasteners
The manufacturing processes of these materials agree with local regulations. The product does not contain dangerous
materials.

Diagrams
The pressure drop, and A-weighted total discharged sound power level depend on the nominal diameter of the
damper and air flow volume at different duct pressures. The type of activation does not influence the airflow
parameter, therefore only one activation type is shown in the diagrams.
