The retrofit solution to make secure doors more convenient.

With the A-opener, the AS 3500, AS 3600 and AS 3600 C automatic multi-point locking systems can be retrofitted to an electromechanical version so that your door can also be unlocked electronically. This gives the door a discreet and appealing appearance and makes connection and installation extremely easy. Moreover, the A-opener can be optimally combined with the digital SIEGENIA access control systems or with access control systems from other manufacturers. Even connection to third-party systems is possible thanks to the innovative IO modules.
