1 FDO A0(A0) Fire Damper FDO in picture with flanges (available as an option) Halton FDO fire dampers are type-approved class A0(A0) fire dampers for use in marine and offshore ventilation systems. The FDO can be installed in circular ducts. All fire dampers have a fusible link and they prevent the spread of fire within the ventilation ductwork. When the blade is in the open position, the device does not cause significant pressure loss, noise or flow disturbance. Fire dampers are set from outside and can be installed in any position. An open-closed indicator is visible on the outside of the damper. Type-approved by most recognized classification societies, class A0 - A0 fire damper when suitably insulated Fixed frame of painted, galvanized or stainless steel. Blades stainless or galvanized steel. Flanges available as an option. Blade contains seals (effective up to 20 ºC) Nominal fuse release temperature 50 ºC, 4 ºC or 100 ºC. Other temperatures available. Very low leakage Automatic electrical, pneumatic or spring operation system available Maximum duct pressure for damper construction 5000 Pa and maximum air velocity 15 m/s PART MATERIAL FINISHIN Frame Carbon steel Painted or galvanised Frame Stainless steel EN (AISI04), EN (AISI1L), EN (AISI1L) - Blades Steel alvanized Blades Stainless steel EN (AISI04), EN (AISI1L), EN (AISI1L) - Maintenance-free bearings Stainless steel EN (AISI1L) - Shafts Stainless steel EN (AISI1L) - FDO - A0(A0) Fire Damper 5

4 FDO PRODUCT OPTIONS Halton FDO is available with following actuators: FDO-EL: Electrical spring return motor; standard actuators being 24 V or 20 V or 120 V. The motor contains built-in open-closed limit switches. Separate junction box included in the EL-model. A wide range of eex-proof actuators available, including a one second closing time function as an option. FDO-PNR: Pneumatic rotating actuator FDO-SP: Manual spring-actuated damper with fusible link DOT: manual override function available for PNR models. A wide range of accessories available. OPERATION PRINCIPLE In the event of a temperature rise in ductwork: FDO-EL: fusible link releases and cuts off operating voltage to the spring return motor, allowing the spring to close the damper blades. The fire damper opens automatically when the fuse has been changed and the operating voltage to the motor is re-established. FDO-PNR: fusible link releases and cuts off operating pressure to the spring return actuator, allowing springs to close the damper blades. The fire damper opens automatically when the fuse has been changed and the pneumatic air supply is re-established. FDO-SP: fusible link releases allowing the spring to close the damper blades. When the fuse has been changed, the fire damper must be reset into open position manually.
