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 Netbell devices 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/48V, 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.
Using Netbell Bell Controller for PA System
The Netbell bell controller can be used with any PA systems to schedule and activate the tones for break time alerts. It’s compactible with Bogen paging and intercom systems, Valcom PA system and other school/factory public address system in the market as long as there is a tone generator built into the system and the system has contact closure tone activation function. The relays on the Netbell controller can be setup to activate different tones on a tone generator depending on how many relays the controller has. For example, a Netbell-2 can be used to activate two tones, Netbell-8 for 8 tones, etc. Wiring each one of the relays to a different tone activation terminal, the relays act as simple closure switches.

This controller is designed for only low voltage control (no more than 48 volts). If you need to control a device greater than 48V, you will need to use an interface relay kit. Click Here to order your interface relay kit, or get one from the option set above.
