Description
The LCN 4040SE Sentronic is a heavy-duty, non-handed door closer and electromagnetic hold-open device for fire and smoke barrier doors. It holds doors open via solenoid until power interruption triggers automatic closure, solving safety code compliance and emergency egress challenges for building managers and facilities teams.
The 4040SE fits interior doors up to 4 feet and mounts on either push or pull side without handed configuration. It includes a standard single-lever track arm, 24V or 120V solenoid (specify voltage), switch board with over-voltage protection, and mounting hardware. As an authorized LCN dealer, E.D. Locks provides expert guidance on voltage selection, integration with alarm systems, and custom finish options. Contact sales@edlocks.com or 1-877-207-6067 for compatibility questions.
