What Graef & Meyer does
Gräf & Meyer GmbH, founded in 1994 and headquartered in Kirkel, Germany, develops, manufactures, and sells EN 54-16 certified voice alarm (Sprachalarmierungsanlagen, SAA) and public address (PA) systems for life safety applications in public buildings and venues. The company's product portfolio centers on three EN 54-16 certified platform families: NEO+ (advanced scalable system up to 1024 zones), NEO (original plug-and-play 2U system), and ONE (compact all-in-one system expandable to 60 zones / 5,000W via ONE-LOOP modules), supported by the EVA 16 2.0 audio management system, EN 54-24 certified speakers (ceiling, column, surface, horn), paging stations, fire brigade control panels (VAP1-FES), amplifiers (SINUS 430 Dps), and the EVAC Control/Cloud remote management software. Core technical architecture includes AES67/Dante audio-over-IP networking at Layer 3, redundant controller failover, continuous speaker line monitoring via the proprietary TFL-2 end-of-line impedance module, and integration with fire alarm panels via MODBUS RTU, RS-485, UDP, and relay interfaces.
The company operates a hybrid hardware-and-services business model: primary revenue from one-time hardware sales of certified voice alarm components, supplemented by professional services including technical training (€390 per external participant, free for existing customers and DIN 14675-certified engineering offices), RMA repair/replacement, and pre-project consulting for planning offices and system integrators. Distribution combines direct field sales in South/East Germany and Austria with an exclusive channel partnership with LDA Audio Tech (Spain) covering DACH plus Benelux (Germany, Luxembourg, Netherlands, Belgium, Austria, Switzerland). In September 2025, LDA Audio Tech completed a full acquisition of Gräf & Meyer's company shares after six years of partnership, consolidating the group while Graef & Meyer retains its brand and DACH/Benelux market operations. The company serves fire protection specifiers, planning offices, system integrators, and end customers across hotels, shopping malls, office buildings, industrial plants, railway stations, airports, and schools, with over 30 years of documented domain expertise, ISO 9001:2015, DIN 14675, and EN 54-16/EN 54-4/EN 54-24 certifications.

Graef & Meyer competitors and assessment
Company assessmentDirect peers
- LDA Audio Tech: Spanish manufacturer of EN 54-16 certified voice alarm and public address systems and now the parent company of Gräf & Meyer following the September 2025 full acquisition. LDA's product lines (NEO, ONE, NEO+) overlap directly with Gräf & Meyer's portfolio, and the two share technology roadmaps and joint rack-assembly operations.
- Ateis: Swiss-headquartered specialist in EN 54-16 voice alarm and PA systems (IDA, BOUTIQUE, DIVA series). Closely comparable mid-sized competitor focused on European life-safety audio, with similar architectural certifications and a comparable DACH customer base.
- TOA Corporation: Japanese manufacturer of EN 54-16 certified voice evacuation systems (VX-3000 series) and PA/speaker products. Direct competitor in European public address and voice alarm tenders, particularly in transport, education, and commercial building segments.
- IED (Innovative Electronic Designs): US-based manufacturer of EN 54-16 voice alarm/paging systems (Globalcom, 500ACS series) primarily serving transportation hubs and large public venues. Comparable niche specialist focused on life-safety audio networking and multi-zone announcement systems.
Others
- Barix: Swiss audio-over-IP and IP paging specialist whose Barionet, Annuncicom, and IPAM products underpin networked PA and voice alarm installations. Overlaps with Gräf & Meyer's AES67/Dante networking direction as an ecosystem enabler for distributed voice alarm systems.
Broad incumbents
- Siemens (Cerberus PRO): Global smart building and fire safety incumbent with EN 54-16 voice alarm systems under the Cerberus PRO brand. Competes for large infrastructure projects and offers voice alarm as part of integrated building management solutions, including the German market where Gräf & Meyer operates.
- Honeywell (Gent by Honeywell, Notifier): Global fire safety incumbent with voice alarm solutions (e.g., Gent Vigilon, Notifier Voice) sold as part of broader fire detection portfolios. Overlaps with Gräf & Meyer in hotels, airports, and large commercial buildings where one-stop fire safety contracting is preferred.
- Eaton (Wheelock Cooper Notification): Global power management and life safety incumbent offering Wheelock and Cooper Notification voice evacuation and mass notification systems. Competes with Gräf & Meyer in commercial, industrial, and public venue projects across Europe and globally.
- Bosch Security Systems: Global incumbent offering Praesideo and Paviro voice alarm/PA systems alongside a much wider fire detection, video surveillance, and intrusion portfolio. Competes with Gräf & Meyer on large public building tenders where full-scope security integrators are preferred.
Emerging players
- RCF Group: Italian professional audio manufacturer expanding into EN 54-16 commercial audio and voice evacuation products (Flexa, DXT series). Comparable to Gräf & Meyer in amplifier and speaker manufacturing heritage, now targeting the same European voice alarm compliance market.
