S-RA1

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.

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).
