Introducing the application features of stainless steel smoke and fire dampers.

The smoke and fire damper actuator's motion detection device includes a housing and a battery pack housed within it. The battery pack is connected to two conductive terminals for the fire damper actuator via a wire and a second wire, respectively. The housing has openings for the wire and second wire to pass through. A switch is串联 on either the wire or the second wire, and the housing features an opening for the switch to be mounted.
The motion detection device addresses the technical issue of difficulty in testing the normal operation of stainless steel smoke and fire dampers after the installation of fire-resistant low-voltage systems in existing technology. Fire dampers are mostly installed at elevated locations such as rooftops and wall tops, preventing issues after the installation of stainless steel smoke and fire dampers. This avoids the redundant and wasteful labor of replacing and adjusting the stainless steel smoke and fire dampers when detection reveals that they are not functioning properly.
The stainless steel smoke and fire damper actuator features a novel structure, reliable operation; excellent airtightness, strong corrosion resistance, and flexible, reliable movement, ensuring the normal and stable output of signals.
