BE230

Siemens BE230 is a robust actuator designed specifically for smoke control dampers. Whether you’re an engineer, facility manager, or safety professional, this device ensures reliable operation during critical scenarios. Let’s explore its features, benefits, and applications.

Key Features

1. Torque Motor (40 Nm):
   • The BE230 boasts a powerful torque motor, providing 360 in-lb (40 Nm) of force.
   • This high torque ensures precise damper movement, even in demanding conditions.
2. Nominal Voltage (AC 230 V):
   • Operating at 230 V AC, the BE230 is suitable for various power supply systems.
   • It ensures consistent performance across different environments.

Highlights

1. On/Off Control:
   • The BE230 offers straightforward 2-wire on/off control.
   • It responds promptly to activation signals, making it ideal for smoke control scenarios.
2. Form Fit Mechanical Interface:
   • The continuous hollow shaft with a form fit of 14x14 mm ensures secure attachment to the damper spindle.
   • This interface minimizes play and guarantees reliable transmission of motion.
3. Direction of Motion Selectable:
   • Whether you need clockwise or counterclockwise rotation, the BE230 allows you to choose the direction of motion during installation.
4. Manual Override with Hand Crank:
   • In emergency situations or during maintenance, the hand crank provides manual control.
   • It ensures that the damper can be operated even without electrical power.
5. IP54 Protection Rating:
   • The BE230 is well-protected against dust and water ingress.
   • It meets IP54 standards, making it suitable for both indoor and outdoor installations.

Applications

1. Smoke Control Systems:
   • The BE230 plays a critical role in smoke evacuation during fire incidents.
   • It ensures that smoke dampers open or close promptly to maintain safe evacuation routes.
2. Building HVAC Systems:
   • Integrating the BE230 into HVAC systems enhances safety.
   • It allows for controlled ventilation and smoke containment in commercial and industrial buildings.
3. Emergency Exits and Stairwells:
   • By operating smoke dampers, the BE230 helps create clear pathways for occupants during emergencies.
   • It contributes to life safety in public spaces.

Safety Considerations

1. Manufacturer Responsibility:
   • The actuator is supplied directly to safety damper manufacturers.
   • The damper manufacturer assumes full responsibility for proper integration and functioning.
2. High Torque Shaft Material:
   • Due to the significant torques applied to the damper shaft, consider using St50 (or higher) material.
   • This ensures durability and prevents shaft deformation.
3. No User-Serviceable Parts:
   • The BE230 does not contain components that users can replace or repair.
   • Any maintenance or adjustments must be performed by qualified professionals.
