The LCN 4040SE-0801 is a robust surface-mounted hydraulic door closer engineered with an integrated electronic hold-open function, specifically designed for stringent interior fire/smoke barrier door applications. Its precision hydraulic control, combined with a durable cast iron body and forged steel arm, ensures reliable operation and adherence to critical safety standards including UL10C and NFPA 101.
Quick Answer
The LCN 4040SE-0801's primary strength lies in its reliable, fire-rated electronic hold-open functionality, ensuring code compliance and controlled door management in critical environments.
✓Integrated Electronic Hold-Open for Fire/Smoke Barrier Doors
✓UL10C and NFPA 101 Fire Rated Compliance
✓Adjustable Closing and Latching Speeds with Hydraulic Back-Check
✓Robust Cast Iron Body with Forged Steel Track Arm
✓ANSI/BHMA A156.15 Certified and ADA Compliant
The LCN 4040SE-0801 is an exceptionally well-engineered hydraulic door closer, ideally suited for critical interior fire/smoke barrier applications where controlled access, automatic closure during emergencies, and long-term durability are paramount. Its integrated electronic hold-open and robust construction, backed by comprehensive certifications, make it a definitive choice for demanding commercial and institutional environments.
✓ Who Should Buy
- •Facilities managers and specifiers for commercial and institutional buildings requiring fire-rated door control with electronic hold-open.
- •Architects designing spaces with stringent fire and life safety codes (UL10C, NFPA 101).
- •Property owners seeking ADA compliant and durable door closers for high-traffic interior doors.
- •Contractors installing hardware on metal or wood fire/smoke barrier doors where reliable, automatic closure is critical.
✕ Who Should Avoid
- •Applications requiring non-fire-rated, basic door control for light residential use where the electronic hold-open feature is not needed.
- •Exterior door installations, as the unit is specifically suited and certified for interior environments.
- •Projects with extremely narrow doors falling outside the specified width capacity.
- •Installations where a delayed action feature is explicitly required for accessibility, as the 4040SE-0801 does not include it.
Product Overview
The LCN 4040SE-0801 represents a professional-grade hydraulic door closer, precisely engineered for interior fire/smoke barrier doors. As part of the distinguished 4040SE series (models 2018-2026), this USA-made, surface-mounted unit features a non-handed design for versatile push or pull side installation on metal or wood doors up to approximately 1219mm wide. Its core functionality is centered around a sophisticated hydraulic mechanism offering adjustable closing and latching speeds, complemented by an essential hydraulic back-check feature to prevent door and frame damage. The standout attribute is its electronic hold-open capability, which automatically releases upon alarm activation, ensuring immediate closure in fire emergencies as per UL10C and NFPA 101 requirements. Constructed with a durable cast iron body and a forged steel track arm (SE Track), finished with a powder coat, the 4040SE-0801 is built for longevity and consistent performance, complying with ANSI/BHMA A156.15 and ADA standards for accessibility.

Engineering Analysis
The LCN 4040SE-0801 employs a high-grade hydraulic system encased within a robust cast iron body, engineered for precise and consistent door control. The internal hydraulic fluid, combined with independently adjustable valves for both closing and latching speeds, allows for meticulous calibration of the door's entire operational cycle. The separate closing speed valve precisely controls the sweep motion from maximum opening (up to 110 degrees) to approximately the last 15 degrees of closing, while the latching speed valve fine-tunes the final closing force, ensuring full latch engagement without unnecessary impact. The integrated hydraulic back-check, a crucial safety feature, provides a cushioning effect against abusive or rapid door opening beyond 70 degrees, protecting the door, frame, and associated hardware from potential damage. The utilization of a forged steel track arm (SE Track) further enhances mechanical integrity, distributing closing forces efficiently and contributing to the closer's overall durability and smooth operation, critical for doors up to ~1219mm width.
A distinguishing engineering aspect of the 4040SE-0801 is its integrated electronic hold-open function, specifically designed for use on fire/smoke barrier doors. This mechanism is directly interlinked with a building's fire alarm system or dedicated smoke detectors. Under normal conditions, it maintains the door in an open position for convenience and traffic flow. Crucially, upon the activation of a fire alarm or loss of system power, the electronic circuit instantly disengages, allowing the calibrated hydraulic closer to immediately and reliably close the fire door. This critical safety feature ensures compartmentalization in the event of a fire, preventing the unchecked spread of smoke and flames. Its compliance with UL10C (Positive Pressure Fire Tests of Door Assemblies) and NFPA 101 (Life Safety Code) is a testament to its stringent design and testing for fire resistance and life safety performance. Furthermore, the unit's certification to ANSI/BHMA A156.15 signifies its adherence to rigorous performance standards for door closer reliability, operational endurance, and safety in daily use, while its ADA compliance ensures accessible operation for all users. The robust cast iron body with a durable powder coat finish and the forged steel arm contribute to exceptional corrosion resistance and an extended service life under demanding interior conditions.
