LCN 4310ME-3351 120V ME 120V Switch Assembly

LCN 4310ME-3351 120V ME Switch Assembly delivers a robust solution for fire and smoke barrier doors with its concealed, heavy-duty, electrically controlled closer/holder. This innovative assembly allows for infinitely adjustable hold-open functionality, ensuring doors remain open until a current interruption occurs, prompting a secure closure. Designed specifically for interior doors up to 4’0", the single lever (track) arm closer operates efficiently, functioning as a full rack and pinion door closer when the hold-open feature is disengaged or interrupted. The built-in "On/Off" switch allows for easy control of the hold-open function, enhancing user convenience. The assembly comes with a standard 2310ME series closer, which includes either a 24V or 120V cylinder, a two-piece metal finish plate, standard arm, track, and a comprehensive screw pack for installation. Handed for both right and left swinging doors, it is compatible with fire alarm systems, ensuring safety compliance (consult factory for specifics). Available in standard or custom powder-coated finishes, with optional plated finishes on the arm, fasteners, and finish plate, this door closer not only prioritizes functionality but also aesthetic adaptability, making it an excellent choice for both commercial installations and projects requiring Baa compliance.
