GSM PRO audio kits with/without coded access are manufactured in the familiar modular 4000 series range with a new style 316-grade stainless steel matt finish. They are available in surface or flush mounting options from single call-button applications up to 12 button kits (please contact us for more information on kits & extra call buttons for larger installations). They are expandable up to 50 call buttons, all with the facility to divert to additional numbers if the first is busy or unanswered (up to 3 divert numbers per button).

GSM PRO series kits now include new programming features such as: programming a primary number and 3 divert numbers in a single text, programming multiple dial to open numbers (up to 5 max.) in a single text, 10 access control timebands, 10 free access timebands and access level assignment (up to 10). The RS485 bus connectivity now allows the GSM PRO module to be expanded to a networkable access control system (up to a total of 8 devices) which can include both proximity, using the new Art.4850R off-board expansion reader, and coded access, using the new Art.4903 keypad.
Videx GSM SMS Wizard App
When the GSM PRO module is networked with the Art.4903 keypad it can be programmed remotely with up to 400 permanent access codes and 32 temporary codes (between 1 – 255 hrs after which time will automatically be deleted). When the keypad is not networked with the GSM PRO module and configured in standalone mode it will operate as a standard Videx keypad with 2 codes (1 code per relay). The keypad also includes blue back-lit button illumination.

Programming can be carried out by SMS text messaging or via a PC using the GSMSK software (connected via the micro USB port) or by using Videx’s new smartphone SMS Wizard App. The App is available to download for free from Google Play (for Android devices) or from the App Store (for iOS devices).

An event log (up to 4000 stored events) is maintained within the GSM module and can be downloaded via the USB port or RS485 bus connection using the GSMSK PC software which also includes many features to simplify the installation and programming process.
