Assa Abloy DC700-D9005: Precision Surface-Mounted Hydraulic Door Closer for Commercial Fire Doors
The Assa Abloy DC700-D9005 is a robust, non-handed surface-mounted hydraulic door closer engineered for critical commercial fire and smoke protection applications. Certified to EN1154, it provides precise control over single action doors up to 1400mm width, ensuring safe and compliant operation.
Quick Answer
The Assa Abloy DC700-D9005's primary strength lies in its EN1154 certified, adjustable EN3-6 power, and critical fire-rated compliance for commercial single action doors.
✓EN1154 Certified: Assured compliance for fire and smoke protection doors.
✓Adjustable Power Size EN3-6: Versatile application for doors up to 1400mm width.
✓Integrated Hydraulic Controls: Features closing speed, latching speed, back-check, and delayed action for precise door movement.
✓Non-Handed Guide Rail Design: Simplifies specification and installation across various door configurations.
✓Robust Steel/Aluminium Construction: Engineered for durability in high-traffic commercial environments.
The Assa Abloy DC700-D9005 stands as a highly reliable and compliant hydraulic door closer, meticulously engineered for critical commercial applications, particularly where fire safety and precise door control are paramount. Its EN1154 certification, adjustable EN3-6 power, and integrated control features (back-check, delayed action, adjustable speeds) make it an optimal choice for managing pedestrian flow while adhering to stringent safety standards.
✓ Who Should Buy
- •Commercial building developers and facility managers requiring EN1154 certified fire/smoke door closers.
- •Architects and specifiers designing projects demanding precise, adjustable door control and accessibility features (delayed action).
- •Door hardware contractors and installers seeking a robust, non-handed, and versatile surface-mounted solution for a wide range of door materials.
✕ Who Should Avoid
- •Applications requiring an integrated hold-open function (as this model is designed for fire doors, it does not feature hold-open).
- •Situations where concealed door closers are aesthetically preferred over surface-mounted units.
- •Installations on extremely lightweight, narrow doors where EN3 power might be excessive (though adjustability helps mitigate this, lower power closers might be more suitable).
Product Overview
The Assa Abloy DC700-D9005 represents a high-performance, surface-mounted hydraulic door closer designed specifically for the rigorous demands of commercial fire and smoke protection doors. Engineered with a durable steel and aluminium body in a sleek black (RAL 9005) finish, this non-handed unit integrates seamlessly with diverse architectural aesthetics. Its versatile EN3-6 adjustable power size accommodates single action doors up to 1400 mm in width, making it suitable for a broad spectrum of wood, metal, and aluminium door types. Key technical features include independent control valves for precise adjustment of both closing and latching speeds, integrated back-check to prevent abusive opening, and a crucial delayed action function for enhanced accessibility. The guide rail arm mechanism ensures smooth, controlled operation with a maximum opening angle of 160°. Fully fire-rated and certified to EN1154 standards, the DC700-D9005 guarantees reliable performance and critical safety compliance, supported by the complete installation hardware included.

Engineering Analysis
The Assa Abloy DC700-D9005 operates on a sophisticated hydraulic system, central to its controlled door closure. The internal hydraulic fluid, regulated by precisely engineered valves, dictates the door's movement dynamics. The primary valve controls the *closing speed*, managing the door's velocity from its maximum opening angle (up to 160°) down to the final latching phase. A secondary, independent valve governs the *latching speed*, providing a critical burst of power just before the door closes fully, ensuring positive engagement with the lock or latch without slamming. This dual-valve system allows installers to fine-tune the door's behavior, optimizing both accessibility and security. The inclusion of *back-check* is a vital protective feature; upon vigorous opening, a hydraulic cushion engages beyond a certain angle (typically around 70-80°), preventing the door from violently striking adjacent walls or objects, thereby protecting the door, frame, and hardware. Furthermore, the *delayed action* function holds the door open for an extended period before initiating closure, a critical feature for high-traffic areas or for accommodating individuals with mobility impairments, improving egress and ingress flow. The non-handed design, achieved through symmetrical hydraulic valving and arm geometry, simplifies inventory management and installation, as the unit can be mounted on either left or right-hand doors in various configurations (e.g., standard, parallel arm, top jamb).
The EN1154 certification is paramount for the Assa Abloy DC700-D9005, affirming its conformity to the European standard for controlled door closing devices. This certification mandates rigorous testing for durability, efficiency, and safety. For fire-rated doors, as is the intended use for the DC700-D9005, EN1154 compliance is non-negotiable, ensuring the closer's ability to reliably shut and latch the door, even under fire conditions, thereby maintaining compartmentation and inhibiting the spread of fire and smoke. The closer's design, specifically its "hold-open function: false" status, is crucial for fire safety as it ensures the door will always close automatically, preventing it from being wedged open and compromising fire separation. The adjustable power size, ranging from EN3 to EN6, allows for precise force selection to match specific door dimensions (up to 1400mm width) and weights, a key aspect of EN1154 where the specified power size must correspond to the door mass and width for optimal performance and safety. While a specific cycle test rating is not provided, EN1154 typically requires a minimum of 500,000 cycles for closers used on fire and smoke control doors, implying a robust design for sustained performance in commercial environments. Adherence to DIN18040 (Accessibility) and CEN/TR15894 (Guidance on Selection) further underscores its suitability for inclusive design and informed application. The robust steel/aluminium construction (net weight 2.7kg) ensures the mechanical integrity required to withstand operational stresses over its lifecycle.
