Tetronik

What Tetronik does

Tetronik Kommunikationstechnik GmbH is a privately held German manufacturer founded in 1971 and headquartered in Taunusstein, with branch offices in Düsseldorf and Altenburg. The company designs, manufactures, installs, and services the FN 6000® nurse call and communication platform — a server-based system built on a Systembus architecture that connects IP line modules to room electronics (IMA-Module), call units, displays, and a centralized management software stack (Version 7.x). The platform supports voice communication, DECT and Android-based mobile notification, fire alarm integration via ESPA 4.4.4, wanderer protection (Ident-Funk, i2-Motion, Teratron), and a proprietary 2-wire retrofit solution that enables modernization of legacy phone-based call systems without re-cabling. All products comply with DIN VDE 0834-1, and the personal emergency signal system is DGUV-certified under DIN VDE V 0825-1.

Tetronik sells its FN 6000® systems primarily into German healthcare facilities (hospitals, nursing homes, senior care homes, hospices, rehabilitation centers), with secondary presence in correctional facilities, industrial sites, and transportation. The customer roster evidenced in public materials is skewed toward small-to-mid-sized care providers, alongside charitable donations to hospice and disability support organizations. Distribution is exclusively direct: regional account managers, key account managers, and the company's own installation teams deliver projects from site survey through commissioning and staff training. A 24/7 service hotline, remote maintenance (Fernwartung), and annual maintenance contracts create a recurring service revenue layer atop the hardware sale.

Revenue is generated through four streams: hardware sales (servers, IP line modules, IMA room electronics, call units, displays, vandal-resistant variants), software module licensing (modular add-ons for voice, DECT, ESPA, SIP, SMS, E-Mail, graphics, tenant management, Android client), installation and project services, and recurring maintenance contracts. Pricing is quote-based with no public list prices. The company employs 11–50 people, has no disclosed external investors, and operates with stable long-tenured management. Geographic reach is concentrated in Germany with established presence in the Netherlands via the HerTronik B.V. holding (formed 2006 alongside the acquisition of Schoonderbeek Elektronica Systemen B.V.) and recent expansion into Arabian markets.
