Mechanics meets access control

Mechanics and electronics combined

The CES transponder clip
The transponder clip allows CES’s mechanical profile systems to be easily combined with CES’s electronic locking systems and the AccessOne access control system. This creates flexible hybrid solutions that combine mechanical security with electronic organisation. Existing locking systems can be expanded in stages and adapted to new requirements without any disruption to the system and with maximum planning reliability.
