Product Overview
The LCN 4040SE-0805 represents a pinnacle in door control technology, combining robust mechanical design with advanced electronic functionality. This surface-mounted, non-handed hydraulic door closer features a durable cast iron body and a heavy-duty forged steel track arm, designed to manage interior fire/smoke barrier doors up to approximately 1219mm in width. Its core strength lies in its adjustable power size, ranging from 1 to 4, allowing for tailored closing force to suit various door weights and operational needs. Critical safety features include UL Listing and compliance with NFPA 101, making it indispensable for life safety applications. The integrated electronic hold-open function provides operational flexibility, holding the door at angles up to 110 degrees, while ensuring automatic release upon activation of a fire alarm system. Fine-tuning of door movement is achieved through adjustable closing and latching speed valves, complemented by an effective backcheck feature that prevents uncontrolled door opening.

Engineering Analysis
### Hydraulic Mechanics & Control Precision
The LCN 4040SE-0805 employs a sophisticated hydraulic system within its cast iron body, delivering precise and consistent door control. Independent, adjustable valves for both closing speed and latching speed allow for granular customization of the door's arc of travel and its final securement. The hydraulic fluid within the system provides a smooth, regulated resistance, preventing abrupt door movements and ensuring quiet operation. Furthermore, the integrated backcheck function engages at approximately 70 degrees of opening, cushioning the door's swing to protect both the door and surrounding frames from damage caused by excessive force or wind. This system ensures not only controlled closure but also longevity of the door assembly.
### Compliance & Fire Safety Integration
Adherence to ANSI/BHMA A156.15 standards signifies the 4040SE-0805's rigorous testing for operational reliability, durability, and safety performance in commercial environments. Crucially, its UL Listing and compliance with NFPA 101 (Life Safety Code) underscore its suitability for fire and smoke barrier doors. The electronic hold-open mechanism, which allows doors to remain open for convenience, is engineered to automatically release the door upon activation of the building's fire alarm system, initiating controlled closure to maintain the integrity of fire compartments. This critical safety integration ensures that in the event of an emergency, fire and smoke containment protocols are immediately enforced without human intervention, making it a cornerstone component of modern fire safety strategies.
### Robust Construction & Performance
Constructed with a robust cast iron body and a durable forged steel track arm, the 4040SE-0805 is built for enduring performance in high-traffic settings. The adjustable power size from 1 to 4 allows for field optimization, adapting to various door dimensions and environmental factors. While a specific cycle test rating is not provided, the ANSI/BHMA A156.15 certification implies robust durability testing. The unit's non-handed design simplifies specification and installation, enhancing its versatility across a wide range of interior metal and wood door applications.
