COMBINATION FIRE AND SMOKE DAMPER 1-1/2 HR LEAKAGE RESISTANCE CLASS II 250 O F FILE NO: R22165 Product Description Combination Fire / 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 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 or in walls or ceiling slabs made from concrete, brick and lightweight partition walls. In today's life safety products markets, many building code require Fire dampers, Smoke dampers and Combination Fire & Smoke dampers to be inspected for proper operation. Usually Fire and Combination Fire & Smoke dampers are supplied with a fusible linkage that is a one time device and generally limited within a specified temperature rating (165 or 212 F). Once this link has meet the elevated temperature, it can no longer be used and must be replaced with an identical link for further operation. "SAFID" introducing "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" sensor is a manual reset type and can be reset after the temperature has cooled down below the sensor set point. This feature allow the ease of operating and resetting the damper in a matter of seconds without replacing the links. It is reusable / ressettable heat responsive device that can only be reset after a visual inspection of the damper. The "ERL" requires factory installation and wiring together with the qualified actuator to meet "UL" requirements. The "ERL" in combination with a qualified electric actuators provides controlled closure and eliminates the instantaneous damper closure associated with traditional fusible links that can damage the entire ductworks. The duct smoke detector can be wired in series with the "ERL" to close the damper during smoke control mode. 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 with "NFPA90A & 92A" latest edition and local codes. 1

Actuators 91 BELIMO Model: BF230-S-ME ERL Model: BAE165US Sequence of operation: Fire Mode: The ERL (Thermoelectric Tripping Device) resettable link has a thermal sensor switch that interrups the power supply to the fire & smoke control actuator as soon as the duct temperature exceeds 165ºF caused by a fire. When the power supply is interrupted, the energy stored in the spring of the fire & smoke damper actuator moves the damper back to its safe position. The damper can be open again by pressing the reset button on ERL after the temperature cooled down below 165ºF. Smoke Mode: When a signal detected through normally closed smoke detector (by others) connection, the power supply to the fire & smoke damper actuator will be interrupted. The energy stored in the damper actuator moves the damper back to its safe position and remain closed until the smoke signal close down. The system will reset after power is reapplied to the actuator and damper will open. By placing an optional control switch (by others) in the closed position can be close the damper if required at any time. Typical Wiring Diagrams 10
