Specifications
Single compartment smoke control dampers are for use in smoke and heat control system serving a single compartment. These dampers can be opened or closed to manage the smoke extract or makeup air path. The damper blade is driven by a drive open/drive closed actuator which is mounted within a fire rated enclosure. The SEDS-L damper can be used in systems with Automatic activation (AA) where dampers have a single operation on activation and in systems with Manual intervention (MA) where dampers may have delayed activation or may have more than one operation such as post event smoke clearance or firefighter's override. The SEDS-L damper can be installed in smoke extraction ducts tested to EN 1366-9.
