Page 3: General Information
® NORDfire | SEDS-L General Information 1. Description Fig. 1. Damper SEDS-L Smoke extraction dampers - single are shutters in smoke exhaust piping systems. Dampers are designed to remove heat and combustion products (e.g. smoke) from single fire compartment. In the event of fire the Smoke and Fire ventila- tion system opens the damper in the affected section which removes combustion products and heat from this section. - Page 4 ® NORDfire | SEDS-L installing the damper or when connecting the actuator power cable. The cable entry must meet a minimum fire resistance of 30 minutes. Design .65 Fig. 2. Act. mechanism in the cover Belimo modulating actuators, BEN (BEE)-SR series for 24V AC/DC are specially designed for remote control of smoke control dampers.

Results of regular checks, imperfections found and all-important facts connected with the damper function must be recorded in the "FIRE BOOK" and immediately reported to the operator. ® NORDfire | SEDS-L Before entering the dampers into operation after their assembly and by sequential checks, the following checks must be carried out for all designs. -
Page 13: Installation
® NORDfire | SEDS-L Installation 6. Placement and Assembly Smoke extraction dampers single are designed to remove heat and combustion products (e.g. smoke) from single fire compartment according EN1366-9. Smoke extraction dampers single are designed for installation with horizontal or vertical axis of the blades. Backtoback smoke exhaust duct has to be hung or supported so as all load transfer from the backtoback smoke exhaust duct to the damper is absolutely excluded. -
