The Netbell-8 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, 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 easy-to-use 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 schools, factories, warehouses to build a fully automated web-based timed alert system for signaling class changes, shift rotations, breaks, general alarm and any other timed signal applications.

Netbell-8 is a board without an enclosure. With the 8 relay outputs, you can control up to 8 bells/buzzer and other timed signal equipment (12V/24V, 5A). Each device can be connected at 500 feet away from the controller with 16AWG cable (250ft/18AWG) with a suitable power source.
It's ready to go out of the box, and you need only connect the unit to the power outlet and network with the provided cables; 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 BellScheduler desk app.
For those who wish to forego networking the Netbell-8, 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-8 bell controller has 8 dry contact relays (12V/24V/48V@5A) that can be used to control up to 8 low 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
