All Videx 3000 series telephones are manufactured from smooth ABS plastic and have a minimum of two buttons. The "door open" button communicates with the entrance panel and opens the lock while the "auxiliary button" can be programmed to control stair lights or even open another lock. The exception to this are some Smart Line audio handsets which have only the "door open" button, providing an even more cost effective solution for your installation.
These audio handsets can be added to your Videx door entry kit, enabling the user to answer their door in multiple areas of the property. Since 12V AC buzzer versions are available, these handsets work well as replacements when refurbishing older systems.
