LCN 4310ME-3351 24V ME 24V Switch Assembly

LCN 4310ME-3351 24V ME Switch Assembly offers a robust solution for managing fire and smoke barrier doors with its concealed heavy-duty design. This electrically controlled closer/holder is engineered to provide infinitely adjustable hold-open functionality, ensuring that doors remain open until interrupted by a current, allowing for a seamless and safe closure. Designed specifically for interior doors up to 4'0", the single lever (track) arm closer operates as a full rack and pinion door closer when the hold-open feature is disengaged or current is interrupted. It is handed for either right or left swinging doors, providing versatility in various commercial settings. The built-in "On/Off" switch allows for easy control of the hold-open function, and the unit interfaces with fire alarm systems, making it a reliable choice for safety compliance. The LCN 4310ME-3351 includes a standard 2310ME series closer with a choice of 24V or 120V cylinder, along with a two-piece metal finish plate and a complete screw pack for installation. Available in standard or optional custom powder coated finishes, as well as optional plated finishes for the arm, fasteners, and finish plate, this door closer combines functionality with aesthetic appeal, meeting both commercial and residential needs effectively.
