Overview
The Netbell-KB-C combines an extra loud break buzzer system with a matching 4-inch digital clock, built for warehouses and factories that want loud, reliable break signaling and a synchronized time display. The volume-adjustable 110 dBA buzzer covers up to 25,000 sq. ft., and you can add a second buzzer to reach 50,000 sq. ft. total. The clock plugs into the controller and syncs its time automatically from the Netbell, with digits readable up to 250 feet, and everything comes fully wired in a NEMA-rated box. Built on a TCP/IP platform with a built-in web server, you schedule up to 500 events from any browser with no additional software and no monthly fees, and you can wire a push switch for manual emergency signaling. A cost-effective warehouse buzzer system upgrade from an old bell timer.
How It Works
- Power the unit and connect it to your network — it can go anywhere on your network, no direct PC connection needed.
- Plug in the 4-inch digital clock — it syncs its time from the controller automatically, no setup.
- Add buzzer schedules from a standard web browser (or the free BellScheduler desktop app) — up to 500 events.
