LCN Closers

The 2310ME, 4310ME and 4410ME Sentronic closers provide adjustable hold-open points for fire and smoke barrier doors. The closers are UL listed for metal smoke barriers or labeled fire doors. They also meet ANSI/BHMA A156.15 and NFPA 101 life safety code standards. Each closer is backed by a 2-year limited warranty, offers optional plated finishes and integrates with existing fire and life safety systems, minimizing danger to life and property under fire conditions. The 2310ME, 4310ME and 4410ME series function as full rack-and-pinion door closers when hold-open is not engaged or the electrical current is interrupted. The finishes, cylinder functions and installation accessories meet virtually all life and safety requirements. The 4310ME Sentronic is a heavy duty, electrically controlled closer/holder designed to provide infinitely adjustable hold open for fire and smoke barrier doors. Door is held open until current interruption releases mechanism and the door closes. Single lever (track) arm closer is specifically designed for interior doors. Choice of finishes, cylinder functions, and installation accessories meet virtually all life safety requirements. An ME provides only the closer / holder function.
