ASSA ABLOY Cam-Motion® door closers remove unseen barriers to building use by making opening more comfortable

At every step of a building design or specification process, stakeholders have a choice. Decisions made at this stage materially impact the building experience far in the future.

For this reason, many regulations aim to protect the accessibility rights of all kinds of users, young and old, ambulant or wheelchair-using.

CEN/TR 158941

One key European guidance document that promotes accessibility for all is CEN/TR 158941.

To meet the recommendations of this technical report, door closers must offer a rapidly decreasing opening force. The force a user must apply should be reduced by 40% when an opening angle of 60° is reached. 

CEN/TR 15894

When every important door opens comfortably, building owners offer a more equal experience

Compliance with CEN/TR 15894 gives architects, building managers, and users confidence that a building design makes occupants safer; and that the interior is reliable and user-friendly, with special attention paid to children, the elderly, and the disabled. When every important door opens comfortably, building owners offer a more equal experience and encourage participation.

Fitting the right door closer to an entrance or interior door can make the difference between a truly accessible building and one that simply swaps one barrier for another. But not every door closer can do the job that building designers and retrofitters require. 

Remove barriers to access with Cam-Motion® technology

Rack and pinion door closers with guide rails may be hard for less-able building users to open. Many won’t have the strength to exert the necessary opening force in comfort. Cam-Motion can help.

Door closers equipped with ASSA ABLOY’s Cam-Motion technology guarantee ergonomic and convenient openings for everyone.

Comfortable opening experience

They exceed the recommendations of CEN/TR 15894 by mirroring the power of the human elbow

Unlike traditional rack and pinion guide rail systems, Cam-Motion guide rail door closers need a push-force that falls rapidly. They exceed the recommendations of CEN/TR 15894 by mirroring the power of the human elbow, where torque also reduces sharply as the arm extends.

This creates a much more comfortable opening experience without sacrificing the force required to close properly to meet other safety standards.

Automatic door closers

“Typical symmetric and asymmetric rack and pinion door closers with guide rail are not able to match this performance,” explains Andreas Gmelin, Product Management and Business Development Director Door Closers at ASSA ABLOY Opening Solutions EMEIA.

“Critically, the door also closes fully and automatically, for user convenience, energy efficiency, building security, and to comply with fire protection rules. No one should have to pull hard to shut and maintain a building’s fire protection.” 

Optional closing delay

The backcheck function as standard across the range slows the door’s final opening section

ASSA ABLOY Cam-Motion door closers also offer optional closing delay, giving users extra time to pass through.

To protect the frame and prevent banging into walls, the backcheck function as standard across the range slows the door’s final opening section.

Maximum convenience and safety for the long-term 

Cam-Motion door closers also maximise specification and installation flexibility. Their symmetric cam design allows fitting to either frame or door and on a hinge or non-hinge side; no compromises or installer workarounds are needed. A range of models can equip single- and double-leaf doors. 

In meeting these important accessibility criteria, they do not sacrifice durability or fire resistance. All ASSA ABLOY Cam-Motion devices are tested to EN 1154 standards for fire and smoke protection. Optional built-in smoke detectors and electromechanical closing offer enhanced protection.
