With ALS (Adaptive Length Profile) and DUAL (Dual Code System), EVVA brought two new cost-effective mechanical systems to the market. In 2009 DUAL was replaced by the ICS system. On top of that ELMO, an electronic cylinder system, was developed. On the inside: a thumb turn with an electronic system and batteries that are very easy to replace. On the outside: a mechanical locking mechanism that can be integrated into existing locking systems.
