Introducing the new 4G GSM PRO audiokits, further expanding the flexibility that has made Videx's GSM series so popular. Designed to work on a 4G mobile network, but are also backward compatible with both 2G and 3G networks. They are available as 1 or 2-button kits, and can be expanded up to 50 call buttons using our modular design. They are manufactured in the familiar modular 4000 series range in a 316-grade stainless steel matt finish (suffix /M), also available in a gunmetal grey finish (suffix /BL). The GSM audiokits include the 4903 keypad with blue back-lit buttons, that when connected via the RS485 bus, can be programmed remotely. With RS485 bus connectivity the GSM kits can be expanded to a networkable access control system (up to a total of 8 devices) which can include both proximity using additional 4850R proximity readers and coded access with additional 4903 keypads. The kits have all the original features of the previous GSM PRO series audio kits where programming and setup can be carried out by either using Videx's new GSM mobile Apps (for both installers and users), by text messages, a web browser or using the GSMSK PC software (including a remote "over the air" programming feature).
