Overview
The Netbell-2-2Bel is a one-stop solution for schools, factories and warehouses to build an automatic network break bell system for signaling class changes, shift rotations, breaks, general alarm and any other timed signal applications. This kit includes one Netbell-2 web-based Bell Controller, two signal bells (6 inch 86dB, each bell can cover up to 8000 sqf office area), two weatherproof back boxes for wall mounting, two 12VDC power supplies to power the bell and two 10ft power cables. The bell can be connected at 250 ft away with 18AWG cable (500 ft/16AWG) to the Netbell-2 controller, you will have everything needed for installation and operation.

The Netbell-2 web-based bell controller is built on a TCP/IP platform with a built-in web server and special software designed for scheduling a bell system. 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 easy-to-use BellScheduler desk app, manage & schedule multiple Netbells in a few clicks, making the management of your bell systems incredibly easy. With the digital inputs you can wire a push switch for ringing bells manually.
It's ready to go out of the box, and you need only connect the unit to power 12VDC or POE and network with the provided cable; it can be connected anywhere on the network and does not require a direct connection to a PC. Scheduling and setup are accessed through any standard web browser or the BellScheduler desk app. For those who wish to forego networking the Netbell-2, it is also able to function as a stand-alone device. Connecting the unit to a PC, upload the bell schedules, then remove, and it will function as scheduled.
The Key Features
•COMPACT AND SELF-CONTAINED: Network enabled, all-in-one automatic bell controller 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: The Netbell-2 bell controller has 2 dry contact relays (1-Form-A relays 110/220@10A) that allow you to control up to 2 line voltage bells/buzzers or other timed signal equipment, 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
