/31 | 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.
/31 | S-RA1 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.
/31 | S-RA1 Technical Parameters Durability Test • Test procedure with 10000 cycles and actuator control (rotation from 0° to 90°) • No change of the necessary properties. • Test procedure with 10000 cycles and actuator control for “mod” classification (rotation from 45° to 60°) • No change of the necessary properties.

/31 | S-RA1 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. Diagrams for Extract S-RA1-...-B230 S-RA1-...

/31 | S-RA1 Product Handling Warning Some damper parts can have sharp edges. To prevent injuries, use gloves when you install or move the damper. If you use or operate the damper incorrectly, there is a risk of: - electric shock. - fire. - other damage. Ensure that installation is performed by a trained person. The S-RA1 is made of sheet metal. Be careful when you move the smoke control damper. It is necessary to move the bigger dampers with suitable lifting equipment (forklift, crane).

/31 | S-RA1 Electrical Connections WARNING • Risk of electric shock. • Stop the power supply before you do work on electrical equipment. • Only approved electricians can do work on the electrical system. To access the electrical parts of this product follow instructions in "Product Handling" section.
/31 | S-RA1 Type of Activation B230 • The circuit switch between wires 2 and 3 is not part of the damper supply. • When the power supply is connected to wires 1 and 3, the actuator moves to the OPEN position. • When the power supply is connected to wires 1 and 2, the actuator moves to the CLOSED position.
/31 | S-RA1 Type of Activation B24 • The circuit switch between wires 2 and 3 is not part of the damper supply. • When the power supply is connected to wires 1 and 3, the actuator moves to the OPEN position. • When the power supply is connected to wires 1 and 2, the actuator moves to the CLOSED position.
/31 | S-RA1 Type of Activation B24-W This type of activation has cable connectors for the supply and communication unit (the communication unit is not part of the mechanism). • The circuit switch between wires 2 and 3 is not part of the damper supply. • When the power supply is connected to wires 1 and 3, the actuator moves to the OPEN position. • When the power supply is connected to wires 1 and 2, the actuator moves to the CLOSED position.
/31 | S-RA1 Type of Activation B24-SR 24V AC/DC Belimo Actuator, modulated (0)2..10V • When power supply is connected to wires 1 and 3, actuator drives to position OPEN. • When power supply is connected to wires 1 and 2, actuator drives to position CLOSED. Notes: • CAUTION: Main power supply voltage! • Parallel connection of more actuators possible when the power consumption and switching threshold is observed! • Operating range Y - DC (0)2...10 V • Input Impedance - 100 kΩ • Position feedback U - DC 2..
/31 | S-RA1 Type of Activation BST0 • The actuator and the control module are factory wired. • Connect the supply voltage to the connecting cable (approx. 1 m, with ferrules). • The 2-wire cable a/b to the BKSE24-6 is connected to terminals 6 and 7 (screw terminals for 2 x 1.5 mm^2 wire). Terminals 1 and 5 may not be assigned. • The BKNE230-24 transmits the damper position OPEN/CLOSED and fault messages to the BKSE24-6.
/31 | S-RA1 Operation Manual Functionality Check After you install the damper, make sure that you set it to its “closed” operating position. If you use the damper to remove pollutants, make sure that you set it to its “open” operating position. Connect the actuator to the related electric power supply (refer to the “Electrical connections” section). This procedure starts the actuator and sets the damper to its operating position.
/31 | S-RA1 To do a visual check of the internal parts of the damper, dismount the inspection lid or the grille. This will give you access to the internal parts. Also, if the damper has an mechanism lid, you can open the lid to access the internal parts. Do a check of these items of the internal side of the damper: • Make sure that there are no foreign objects or layers of contamination in the air distribution systems of the damper.
