What G&N does

G&N Gefahrenmelde- und Nachrichtentechnik GmbH is a German certified specialist installer (Facherrichter) of fire alarm, hazard detection, security, building automation, and IT/telecommunications infrastructure systems, headquartered in Wartenberg and operating under the broader G&N Gruppe. Founded in 1996, the company employs more than 300 people across nine regional locations in Germany (Wartenberg, Frankfurt, Langenfeld, Gießen, Barsbüttel, Essen, Pfungstadt, Montabaur, Berlin) and holds multiple VdS certifications, DIN 14675 specialist firm status for fire and voice alarm systems, and DIN EN 16763 service provider certification. Its product portfolio spans Brandmeldeanlagen (fire alarm systems), Gefahrenmeldeanlagen (hazard/intrusion detection), Sicherheitstechnik (perimeter protection, video surveillance, video intercom, access control, panic alarms), Gebäudeautomation (B-CON, KNX/EIB, Smart Building), IT-Infrastruktur and Telekommunikation, and Elektrotechnik & Niederspannungstechnik, complemented by a 24/7 Notruf- und Serviceleitstelle (emergency and service control center), maintenance and modernization services, fire protection planning, and an in-house Schulungszentrum (training center).

The company generates revenue through three streams: (1) one-time project-based revenue from planning, installation, and commissioning of fire alarm, hazard detection, and security systems; (2) recurring maintenance and service contracts tied to the installed base; and (3) recurring 24/7 alarm monitoring subscriptions via the in-house control center. Pricing is quote-based per project, with multi-year contract cadence. Go-to-market is enterprise field sales — direct engagement with industrial, commercial, public-sector, and private customers — supplemented by a broad digital presence (LinkedIn, Facebook, Instagram, YouTube, XING, TikTok), a dedicated Sicherheitsjournal, downloadable brochures, and manufacturer/partner relationships. The group is organized under G&N Holding GmbH as the parent, with G&N Gefahrenmelde- und Nachrichtentechnik GmbH and six wholly-owned, brand-retained subsidiaries (B+M Sicherheitstechnik Plauen, BRAUNE, SSP Schwachstrom-Partner, TELROTH ITKS, WIESENT Sicherheitssysteme, Renz Sicherheitstechnik). Management comprises Geschäftsführer Lars Habermehl and Philipp Bertelsmeier. No private equity, venture capital, or institutional investor involvement is evidenced in the source data.
