DFA 127 Inverse Operator - Opens without Power

Record DFA 127 INVERSE – Automatic Swing Door Operator with Fail-Safe Opening Function

The Record DFA 127 INVERSE is a specially engineered swing door operator designed to open doors automatically in the event of a power failure, making it ideal for emergency and safety-critical applications. Unlike standard swing door drives, the INVERSE stores the energy required for opening during its motor-driven closing cycle via an integrated spring mechanism. This enables reliable, mains-free opening when triggered by events such as smoke, fire, or loss of power.

Key Features & Benefits:

• Opens Without Power:
  Mechanically stored energy allows the door to open automatically during a power outage—no emergency backup supply required.

• Smoke & Heat Venting:
  Integrates with smoke and heat extraction systems, enabling automatic door opening for ventilation and smoke evacuation.

• Safe for Escape Routes:
  Perfect for emergency exits and evacuation routes, ensuring doors open automatically for safe and efficient egress.

• Electromagnetic Parking Brake:
  Maintains the door in a closed or parked position without the need for extra electrical locking mechanisms, streamlining installation on interior doors.

• Integrated Opening Stop:
  Built into the operator to eliminate trip hazards, improving pedestrian safety in high-traffic areas.

• Universally Applicable:
  Compatible with a wide range of door configurations and sizes, the DFA 127 INVERSE is suitable for public buildings, hospitals, transportation hubs, and more.
