Description
The LCN 4040SE Sentronic is a heavy-duty electronic door closer and holder for fire and smoke barrier doors. It holds doors open via solenoid until power loss triggers automatic closure. Ideal for facilities requiring code-compliant fire safety on interior doors, this non-handed, non-sized unit provides reliable single-point hold-open function.
The 4040SE uses a single lever track arm and operates on 24V power. It works with standard interior door frames and hardware. As an authorized LCN dealer, E.D.
