Motorized Combination Fire/Smoke Damper CFSD - 80 - 100

Combination fire and smoke dampers provide an automatic means of localizing areas of smoke and or fire in ventilation systems that is greatly contribute to the safety of life and property in the early stage of fire. It prevents the spread of fire and or smoke through ventilation ductworks or wall openings. These type of dampers offer an effective fire or smoke barrier maintaining the integrity in a fire situation and it is combined with low leakage characteristic for smoke management. It is suitable for installation in sheet metal ductworks, openings in walls or floor slabs made from concrete, bricks and in lightweight partition walls.   SAFID introduces “ERL” Thermoelectric Tripping Device (heat sensor) to replace the existing high torque spring/ fusible link fire closure mechanism in all Combination Fire & Smoke dampers and blade type Fire dampers. The “ERL” is thermally responsive bimetal disc/sensor that open and close the electrical contacts at a specific factory calibrated temperature setting. The “ERL” is available in fixed temperature setting at 165°F (74 °C) only.The “ERL” requires factory installation and wiring together with the qualified actuator to meet “UL” requirements. Dampers which allow remote resetting of the damper from a remote location are dangerous. All damper moving parts must be inspected and cycled at every six months and in accordance to the latest NFPA90A/92A and local codes.
