Overview
The Netbell-Ultra 300 is Linortek’s most advanced network bell controller, built for schools and manufacturing facilities that juggle multiple timetables. Thanks to its expanded memory, it stores up to 10 separate bell schedules — regular days, half-days, holidays, and more — each holding up to 500 events, and you can switch between them with a single click or remotely through the RESTful API. It’s built on a TCP/IP platform with a built-in web server, so you schedule and control bells from any browser with no additional software and no monthly fees, and it adds modern security with hardware-based encryption, HTTPS support, and encrypted email alerts. Two relay outputs drive your bells or buzzers, digital inputs let you wire a push switch for emergency ringing, and it can trigger tones on an existing PA system. A powerful, future-proof upgrade from an old bell timer for any school bell system.
