GsmVOX (formerly GSM Komunikator)

Reports alarm conditions over the mobile network. The first version, sold as GSM Komunikator, carried an ordinary Siemens C45 mobile telephone inside the device. FIDRA later moved to GSM modules — Telit first, then Quectel — and the product was renamed GsmVOX. The last version, 5.2, was built until 2025. Manuals for every version are listed below, because units of all of them are still in service. No longer manufactured.
