Overview

The Netbell-2-2Buz is a one-stop break buzzer system for factories, warehouses, and industrial facilities that need to signal shift changes, breaks, and other timed alerts in areas with high ambient noise. The kit includes a Netbell-2 web-based bell controller and two 4-inch extra loud buzzers (110 dBA @ 1m) with weatherproof back boxes — everything needed for installation and operation. The controller is built on a TCP/IP platform with a built-in web server, so you can access, control, and schedule your buzzers over the network or the Internet from any browser, with no additional software and no dedicated computer required. With the digital inputs you can also wire a push switch to sound the buzzers manually in an emergency. It’s an affordable way for any facility to replace an old bell timer with a modern warehouse buzzer system.

How It Works

  • Wire the buzzer to the power supply.
  • Connect the buzzer to the Netbell-2 bell controller.
  • Power the controller and connect it to your network — it can go anywhere on your network, no direct PC connection needed.
  • Add buzzer schedules from a standard web browser (or the free BellScheduler desktop app) — up to 500 events.
