Netbell NTG-C2 Network Public Address & Tone Generator System
Description
The Netbell NTG-C2 is a network-based tone generator and public address system designed to automate shift alerts, break signals, and scheduled announcements through speakers instead of bells or buzzers. The system combines a Netbell NTG tone/message generator, amplifier, and speakers into a single scheduled audio solution. Programming is performed through a web browser, and the system operates stand-alone once schedules are stored.
The NTG-C2 connects directly to an Ethernet network and allows scheduled tones, recorded messages, or announcements to play automatically at programmed times. Multiple events can be scheduled throughout the day, with different tones or messages assigned to different activities such as shift start, breaks, or end-of-day alerts. The system supports both standard tones and custom recorded audio, allowing facilities to replace traditional bell systems with audible voice or tone announcements delivered through speakers.
This configuration is commonly installed in manufacturing facilities, warehouses, schools, and larger commercial environments where audible communication is preferred over mechanical bells. Because scheduling, tone generation, and control are handled internally, no dedicated computer or external software is required during operation. The system is often used when upgrading older bell timers or when expanding an existing paging system to include automated alerts and announcements tied to a single time source.
