When looking to upgrade or replace an existing school & factory break bell system, we have Netbell-K and Netbell-KL self-contained, all-in-one network break bell systems for minimum efforts to setup an automatic bell system. If you don’t mind doing some wiring work, we offer IP – POE solutions for your consideration. Our Netbell-2-1BEL and Netbell-2-2BEL kits can help you build a network break bell system at an affordable price. Now it is easy for schools, factories to have a fully automated web-based timed alert system for signaling shift changes, general alarm breaks and any other timed signal applications.
Our Netbell product comes with a built-in real time clock with NTP automatic Internet time setting and gets its time from a standard internet NTP time server. It looks for time every 10 minutes from NTP server by default (users changeable), which maintains the time between requests with a Real Time Clock (RTC) within the main CPU. There is also a back-up RTC with battery power to maintain time during power interruptions or if not connected to the internet.
For those who wish to forego networking the Netbell, 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. Whether stand-alone or networked, users can easily import/export their existing bell schedules using a simple text format.
