Product Description
Linkage Automatic Door Closer - Universal Right/Left Hand Operation
This linkage door closer system works with standard door closers to provide automatic fire door positioning and closure functionality. The device features adjustable positioning angles for normal door operation while ensuring automatic closure during fire emergencies.
Key Features
- Universal design works for both right and left-handed doors
- Adjustable positioning angles for normal door operation
- Fire control linkage integration for automatic closure
- Compatible with standard mechanical door closers
- Idle feedback connection capability
Operation Principle
During normal conditions, the linkage door closer allows the fire door to open normally with adjustable positioning. When fire is detected, the fire control linkage system cuts power, releasing the linkage mechanism. The door then automatically closes under the standard door closer's function while maintaining idle feedback connectivity.
