Familiar swing door operators ready for more practical applications

New features for two existing variants

The capabilities that a swing door operator must provide are determined by its area of application. Is it about barrier-free passage? Will the operator be used in conjunction with a fire door or access control system? At dormakaba, they can meet every user need in a customized way. With the development of new functions for the ED 100 and ED 250 swing door operators, the usability of these specific solutions is being increased even further.

With the ED 100 and ED 250 swing door operators, dormakaba offers a modular system whose components can be combined in various ways. The total provider of innovative access solutions for better and more secure buildings, rooms and premises, recently developed three new functions for both types. Bas Wouters, active within dormakaba as product marketing manager for Access Automation Solutions (AAS), explains them.  

Sliding arm set for recessions up to 250 mm

From now on, doors can be automated that have up to even 250 mm of setback from the wall. "With the introduction of the CPD 250 slide arm set, we are making this maximum range possible," explains Wouters. "Due to its compact design, the set is already applicable at a door width of 850 millimeters. In addition, this product has been tested on fire-resistant doors with a maximum recoil of 100 millimeters."

Barrier-free escape route

In the event of a fire, swing door automatic door closers normally shut down completely. They then operate as a "standard" door closer. The force required to manually open doors then is usually too great to create a safe and barrier-free escape route. As a result, safe evacuation of a building can take more time than is desirable. With the new EVAC function, to be activated with a contact from an emergency or fire alarm system, dormakaba offers a unique solution. 

"During panic situations, the EVAC function causes the automatic to go into manual mode," Wouters explains. "At the same time, the Power Assist function is activated. This provides motorized support for the manual opening of the swing door, ensuring its effortless and safe operation. Automatic operation of the door also remains possible. However, this does happen with adjusted forces and speeds, so that the system continues to meet all the requirements set for it from European standards."

Integrated emergency power supply 

To ensure business continuity, swing door operators must be connected to a proper emergency power supply. Often this is an external unit that requires cabling. And that entails high costs and space requirements for product and mounting. With a compact, elegant and fully integrated emergency power supply in the swing door operator housing, dormakaba also provides a welcome answer in this area. The battery pack, consisting of rechargeable lithium iron phosphate batteries (LiFEPO4), is characterized not only by high capacity and energy density. A long service life and a significantly higher level of safety are also guaranteed. "Compared to lithium polymer batteries, overheating of these batteries is virtually impossible," Wouters said. "Partly because materials such as cobalt are not used in these batteries. The new UPS emergency power module fits perfectly and can also be easily retrofitted."

Optimal detection

In addition, dormakaba now makes available the Flatscan 3D security sensor. Equipped with not one, but as many as four "laser curtains," this invention achieves a significantly larger "volumetric" detection field. "This field leads to fewer unexpected door movements and provides additional protection of the main closing edge and hinge side," says Wouters. "The result? Less mechanical stress and a higher level of safety. Furthermore, this security sensor features so-called virtual push buttons. This makes it possible, in two freely selectable zones (to be marked with supplied stickers, ed.) in the sensor's detection field, to open the doors automatically and without contact with a simple hand movement. Very convenient and hygienic."
