Details: LCN 4311HSA- US26RHTBTRX HSA Series Sentronic Series Closer

The 4310HSA and 4410HSA Series closers/holders meet ANSI/BHMA A156.15 and NFPA 101 Life Safety Code standards, and come with a 2-year warranty. The closers/holders are designed to integrate with existing fire and life safety systems, minimizing danger to life and property under fire conditions. The closers function as full rack-and-pinion door closers when the hold-open function is not engaged or the electrical current is interrupted. The 4310HSA and 4410HSA Series closers/holders are surface mounted and include a choice of finishes and accessories to meet virtually all high traffic installation requirements. Pedestrians trigger the built-in HSA scanner by moving through the doorway. When the door is opened to 80 degrees or more, the electrical hold-open takes over, minimizing everyday hardware damage. When the last pedestrian is through the door, the system timer releases the hold-open, closing the door with the heavy-duty closer.
