Overview The Netbell-KB is a compact, self-contained design that was created with ease-of-use in mind. The system is built on TCP/IP platform with a built-in web server and special software designed for scheduling a bell system, all software and mounting hardware required for installation and operation are included. With the built-in web interface, you can access, control and schedule bells over a network or the Internet, no additional software or designated computer required. With the special designed BellScheduler desk app, manage & schedule multiple Netbells in a few clicks, making the management of your bell systems incredibly easy. It’s an ideal solution for factories, industrial facilities, warehouses to build a fully automated web-based timed alert system for signaling class changes, shift rotations, breaks and any other timed signal applications in areas of high ambient noise levels.

The Netbell™-KB features a high quality 4 inch high output buzzer (100dBa @10', volume adjustable) that can cover up to 25,000sqf industrial working area, and a completely wired web-based bell controller installed within a NEMA-rated box. There is one additional relay output with a CP connector that provides quick connect/disconnect one external buzzer (not included) if you have a larger area needs to be covered. The external buzzer can be connected at 250 ft away with 18AWG cable (500ft/16AWG) to the Netbell-KB server with a suitable power source.

It's ready to go out of the box, and you need only connect the unit to your AC outlet and an existing network with the provided power transformer and cable; it can be connected anywhere on the network and does not require a direct connection to a PC. For those who wish to forego networking the Netbell-KB, it is also able to function as a stand-alone device. Connect the unit to a PC, add schedules, then remove, and it will function as scheduled.

The Key Features

• COMPACT AND SELF-CONTAINED: Network enabled, all-in-one automatic buzzer system with the hardware and software you need to control your timed alert system. No extra software or designated computer required. Adding schedules from any computer on your network without having to go through the firewall
• FULLY PROGRAMMABLE: Up to 500 programmable event schedules, each event can be set to a different duration for different break time. Create different schedules for different events in a txt format and switch the schedules as needed with a few clicks
• EASY TO USE: With the built-in remote function and BellScheduler desk app, you can manage & schedule multiple Netbells whether in a single building, multiple buildings or multiple locations from one easy-to-use interface, without the need of logging in to each device or hard-wiring the bells to a central control station, making the management of your bell systems incredibly easy
• EASY TO INSTALL: Use as either a network or a standalone device, connect to network or directly to computer for initial setup then it will work as scheduled. With the built-in Real Time Clock and user settable NTP server, you can accurate control of when the bells ring (HH:MM:SS, MM/DD/YYYY, SUNDAY-SATURDAY) or pull the time from your existing NTP server

• EASY TO EXPAND: One additional relay output with a CP connector that provides quick connect/disconnect a second buzzer if you have a larger area needs to be covered (external buzzer is not included, purchased separately). With the remote function and BellScheduler App, you can add multiple bell systems as needed that can share the same schedules or add different schedules Specifications
