S-SA1 Pravokotne dimne lopute

DescriptionS-SA1 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-SA1 dampers have an actuator without a spring. Thus, they have two safety positions: an “open” position and a “closed” position. Power is necessary for the smoke control dampers.S-SA1 dampers are designed for on a duct installations ended with grille, not in the wall or ceiling. The “Installation Methods” section shows the types of installations that are permitted.Special Properties• The pressure level is 3 (-1500 Pa … 500 Pa)• The blade leakage class 3 (compliant with EN 1751)• The casing leakage class C (compliant with EN 1751)• AA – automatic activation (sets the safety position within 60 seconds). No thermal insulation around the actuator needed.Fire ResistivityS-SA1 smoke control dampers have a CE certification that meets the EU’s Construction Products Regulation and complies with Standard EN 12101-8:2011, EN 1366-10:2022, 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) S1500 Cmod AAsingleTypes of Activation• B230 - Activation mechanism with a Belimo actuator (230V AC) and auxiliary switches• B24 - Activation mechanism with a Belimo actuator (24V AC/DC) and auxiliary switches• B24-W - 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 - 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.• BST1 - Activation mechanism with a Belimo actuator (AC/DC 24 V) with a supply and communication unit (SLC powered) BC24-G2 (THC)• BST10 - Activation mechanism with a Belimo actuator (AC/DC 24 V) with a supply and communication unit (AC 230 V) BKNE230-24-PL (Powerline)AccessoriesDetailed information about accessories is available in design.systemair.com• GE1-S-SA1: Extension with Grille for S-SA1DesignThe casing of the S-SA1 is made of a galvanized sheet metal. Blades are made from calcium silicate boards with a silicone rubber gasket which prevent leaks of heat or smoke. The casing has flange on two sides with holes for screws to attach to sheet-metal duct flanges. The damper casing has inspection openings. The mechanisms actuator of the S-SA1 is accesible from the outside.Composition of MaterialsThe product contains these materials:• Galvanized sheet metal• Calcium silicate board• Ethylene-propylene rubber• Galvanized steel fastenersThe manufacturing processes of these materials agree with local regulations. The product does not contain dangerous materials. No silicone caulks are used in the manufacturing processes.
