Ubiquiti UACC-DoorCloser Mechanical Door Closer, Adjustable EN 2-6

Ubiquiti UACC-DoorCloser Mechanical Door Closer

Overview

The Ubiquiti UACC-DoorCloser is a mechanical door closer designed to ensure controlled and safe door closure in UniFi Access deployments. It mounts directly on the door frame or door surface and operates independently without requiring a UniFi Access Control Hub or network connection. The closer prevents doors from slamming, protects door hardware, and ensures reliable engagement of electric locks by managing the final latching motion [citation:5][citation:9].

Adjustable Closing Control

The UACC-DoorCloser provides three independently adjustable speeds for precise control over door movement. Closing speed governs how fast the door moves from fully open to approximately 15 degrees before closing. Latching speed regulates the final 10–15 degrees right before the door latches, ensuring secure engagement without bouncing or slamming. Backcheck speed adds resistance when the door is forcefully opened beyond 70–85 degrees, protecting the door, walls, and nearby people from damage caused by strong pushes or wind gusts [citation:5].

Spring Force Adjustment

The closer features adjustable spring force ranging from EN 2 to EN 6 on the EU standard, accommodating door widths from 850 mm to 1,400 mm and door weights up to 120 kg. The factory default setting is typically EN 3. Spring tension is adjusted with a screwdriver: clockwise turns increase force, counter-clockwise decreases it. Each increase of one EN size requires approximately 3 clockwise turns. For example, moving from EN 3 to EN 5 requires about 6 to 9 clockwise turns. After each adjustment, the door should be tested for safe closing and compliance [citation:5].

Compatibility and Installation

The UACC-DoorCloser is a mechanical accessory compatible with any standard swing door. It is not an electronic device and does not interface with UniFi Access controllers, readers, or locks. Non-handed design allows installation on either left- or right-opening doors without modification [citation:1][citation:6]. Surface mounting simplifies retrofit installations. The closer is available in US and EU models to match regional standards [citation:5].

Key Features

• Adjustable power size EN 2–6 to match door width and weight requirements [citation:5]
• Independent closing, latching, and back-check speed adjustments [citation:5]
• Non-handed design for left- or right-opening doors [citation:1][citation:6]
• Surface-mount installation without requiring UniFi Access Control Hub [citation:5]
• Maximum door opening angle of 180 degrees [citation:16]

Applications

The UACC-DoorCloser is used in access-controlled doorways where mechanical door management is required. It supports UniFi Access deployments by ensuring doors close reliably against electric strikes, magnetic locks, or bolt locks. The adjustable spring force accommodates a range of door types including wood, metal, and glass doors. Common installations include office entry doors, server room doors, and restricted access areas where controlled closure is essential for security hardware to function correctly [citation:9][citation:16].

DC Supplies Product Note

The UACC-DoorCloser is a mechanical component only—it does not include mounting hardware beyond basic fasteners, and it does not include any electronic components, locks, or UniFi Access controllers. For fire door installations, verify that the closer meets local fire code requirements and is installed according to manufacturer instructions. Door closer Size I (US standard) is not covered by CAN/ULC S133 and is not intended for use on fire or exit doors [citation:5]. The US and EU models differ in power size standards and should be selected based on regional requirements.

Specifications

FAQs

Does the UACC-DoorCloser require power or a network connection?

No. The UACC-DoorCloser is a fully mechanical device. It operates without electricity, batteries, or network connectivity. It functions independently of any UniFi Access control system or hub [citation:5].

Can this door closer be used on fire doors?

Fire door compatibility depends on the specific model and installation. The US Size I configuration is not covered by CAN/ULC S133 and is not intended for fire or exit doors. Verify local fire code requirements and select the appropriate power size for your door before installation [citation:5].

What is the difference between the US and EU models?

The US model uses the US standard power size scale (Size I to VI), while the EU model uses the EN standard (EN 2 to EN 6). Both provide similar adjustment capabilities but are labeled according to regional standards. Select the model that matches your region’s requirements [citation:5][citation:6].

Does the door closer include mounting screws?

Basic mounting fasteners are typically included. For specific installation requirements or unusual door materials, additional hardware may be required. Consult the installation guide for details.
