Linortek has introduced the Netbell IP Paging System, a network-based communication platform designed for schools, manufacturing facilities, warehouses, and commercial buildings. The system uses Power over Ethernet to deliver both power and audio through standard network cabling, eliminating the need for separate amplifiers and dedicated speaker wire typical of traditional public address systems. The company developed the system in response to customer feedback about complexity and support challenges with legacy systems.
According to Linortek President Liyu Nalven, many facilities struggle with systems that require professional contractors for installation and become difficult to modify or troubleshoot over time. By using existing network infrastructure, facilities can deploy the system using their own IT staff rather than specialized AV contractors. The Netbell system is available in two protocol variants. The IP speaker line uses Linortek's proprietary network audio protocol, while the SIP speaker line implements Session Initiation Protocol, allowing direct integration with standards-compliant VoIP phone systems.
Both product lines support unicast, multicast, and broadcast network protocols, with multicast implementation allowing a single audio source to reach multiple speakers simultaneously. Hardware options include horn speakers rated at 30 watts for industrial environments, wall-mounted speakers at 20 watts for corridors, and ceiling-mounted speakers at 30 watts for office spaces. All models operate on 802.3at PoE power standards. The platform supports multiple use cases beyond basic paging, including the Netbell-NTG-B controller module that enables scheduling of up to 500 automated events through a web interface for shift changes, break bells, emergency notifications, or routine announcements.
The system can integrate with building systems such as fire alarms and security panels through digital input connections or RESTful API. For VoIP integration, SIP speakers register directly as extensions on compatible phone systems, while IP speakers require the AU-711-SIP gateway device. Additional hardware includes IP-based microphone call stations with zone control capabilities, two-way intercom terminals for entrance points, and IP call boxes for distributed announcement stations. Operating on local area networks without requiring internet connectivity or cloud services, this architecture eliminates recurring subscription fees common with cloud-based alternatives.
The company states that the system meets OSHA requirements for employee alarm systems in industrial settings. The Netbell IP Paging System is available through Linortek's online store with pre-configured system kits starting at $958 and individual components for custom installations.
