LCN 4311HSA SENTRONIC, Surface-Mounted Heavy Duty Fire/Life Safety Track Closer/Holder - Plated Finish

4311HSA Sentronic, Surface-Mounted, Heavy Duty Fire/Life Safety High Security/Holder

The 4310HSA Sentronic is an electrically controlled Closer/holder designed to provide easy passage for groups of pedestrians through high traffic doors. Pedestrians, moving through the doorway, trigger the built-in scanner. When the Door is opened to 80° or more, the Door is electrically held open to minimize wear and tear on applied Door hardware. After the last pedestrian in a group passes through the doorway, the system timer releases the hold-open, closing the Door under control of the Heavy Duty Closer. Single Lever (track) Arm Closer is specifically designed for pull side mounting. Choice of finishes and accessories meet virtually all high traffic installation requirements.

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° or more, the electrical hold-open takes over, minimizing everyday hardware damage.
