Cam Motion Technology
A key feature of the Assa DC500A is its cam motion operating mechanism. Unlike conventional door closers that use a rack-and-pinion arrangement, cam action technology is designed to provide a more favourable opening force characteristic.
This can make the door feel lighter and easier to open, particularly during the initial part of the opening cycle. It is a useful advantage in buildings where doors are operated frequently throughout the day or where ease of access is an important consideration.
The mechanism also provides controlled closing performance, helping the door return towards its closed position without relying on the user to close it manually.
Adjustable EN 1–4 Closing Power
The DC500A offers an adjustable closing power range of EN 1–4, providing flexibility when specifying door control hardware for different applications.
The appropriate power setting depends on factors such as door width, weight, wind conditions, latch resistance and the requirements of the installation. Correct adjustment is essential to achieve effective closing performance without making the door unnecessarily difficult to open.
When selecting a door closer, installers should ensure that the chosen power setting is appropriate for the actual door and its surrounding conditions. The EN power classification alone does not guarantee suitability for every door within a particular width or weight range.
Integrated Backcheck Function
The Assa DC500A incorporates a backcheck function to help control the door as it is opened towards its maximum opening angle.
Backcheck provides a cushioning effect that helps resist sudden or forceful opening movements. This can be particularly beneficial in busy commercial premises, offices, schools, healthcare facilities and other environments where doors may be opened quickly or pushed with considerable force.
By helping to reduce the impact of uncontrolled opening, backcheck can contribute to protecting the door, frame, adjacent walls and nearby fittings from avoidable damage.
Please note: Backcheck is intended to cushion the opening action; it should not be relied upon as a doorstop or as a substitute for a suitable mechanical door stop where one is required.
Applications
The Assa DC500A Silver Cam Motion Door Closer is suitable for consideration across a variety of building types, including:
-
Commercial offices and workplaces
-
Retail premises and shops
-
Educational buildings
-
Healthcare and public-sector environments
-
Apartment blocks and communal areas
-
General commercial and light-duty institutional applications
-
Refurbishment and replacement door hardware projects
Final suitability will depend on the door's dimensions, weight, usage frequency, installation arrangement and any applicable accessibility or fire-door requirements.
Installation and Adjustment
For reliable performance, the Assa DC500A should be installed in accordance with the manufacturer's instructions and the approved fixing arrangement for the particular door and frame.
Before installation, check the door's size and weight, the intended mounting position, the available fixing substrate and any clearance restrictions. Once fitted, the closer should be adjusted to provide an appropriate closing action and ensure that the door closes securely under the conditions in which it will be used.
Where the closer is installed on a fire-resisting doorset, the complete installation must be suitable for that doorset and meet the relevant requirements. The closer must not be assumed suitable for every fire-door application solely because it is a door-closing device.
Professional installation is recommended where the closer forms part of a fire-door assembly or where specific access, safety or building regulations apply.
