Cam-Motion Ensures Everyone Can Open Door Without Struggle
Can everyone who passes through your building open its doors in comfort? Even elderly, very young or less-able building users?
Struggling to open or close a door can be inconvenient, annoying and embarrassing. Difficult doors build a barrier to access. Instead of making a building open and welcoming, they shut many users out – literally.
And no one should have to pull hard to shut a door and maintain a building’s fire protection.
The solution – a door closer – can sometimes make the problem even worse. Depending what devices you choose, door closers may simply be erecting brand new barriers
Regulations and barrier-free access
Many national and trans-national regulations protect the accessibility rights of all types of users – young and old, ambulant or wheelchair-using. One important European guidance which promotes accessibility for all is CEN/TR 15894.
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.
To meet its technical recommendations, door closers must open with rapidly decreasing force. The force a user must apply should reduce by 40% when the door’s opening angle reaches 60°.
When every important door opens comfortably, building owners offer a more inclusive experience. Fitting the right door closer at an entrance or interior door makes the difference between a truly accessible building and one which just swaps one barrier for another.
Remove hidden barriers with Cam-Motion Door Closers
Rack and pinion door closers with guide rail are often hard for less-able building users to open. Many won’t have the strength to comfortably exert the necessary force.
Door closers equipped with ASSA ABLOY’s Cam-Motion technology guarantee ergonomic and convenient opening for everyone. Cam-Motion does the heavy lifting so building users don’t have to.
Unlike traditional rack and pinion guide rail systems, Cam-Motion guide rail door closers require 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 comfortable opening experience without sacrificing force required to close properly to meet other safety standards.
Typical symmetric and asymmetric rack and pinion door closers with guide rail are not able to match this performance.
Critically, with Cam-Motion, a door also closes fully and automatically, for user convenience, energy efficiency, building security and to comply with fire protection rules.
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, backcheck function as standard slows the door’s final opening section.
Convenience, safety and long-term durability
Cam-Motion door closers also maximize specification and installation flexibility.
Their symmetric cam design allows fitting to either frame or door, and on 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 standard for fire and smoke protection. Optional built-in smoke detectors and electromechanical closing provide enhanced protection.
