LCN SEH Series Holder


The Sentronic® SEH Series provides a single-point hold-open function for fire and smoke barrier doors that must be used with opposite-side-mounted UL listed door closers. It is backed by a 2-year limited warranty and meets ANSI/BHMA A156.15 and NFPA 101 Life Safety Code standards. The SEH Series is UL listed for metal smoke barrier or labeled fire doors and cUL listed for self-closing doors without hold-open.

The SEH Series features a single-lever arm specifically designed for interior doors. It holds the door open until an electrical current interruption releases the holding mechanism, allowing the door to close. It also integrates with existing fire and life safety systems, minimizing danger under fire conditions.
