UB‑501 Automatic School Bell System – Powerful & Smart Classroom Management
The UB‑501 from SuperSync is a cutting-edge programmable school bell system designed to automate and streamline daily scheduling in educational and institutional environments. It’s not just an amplifier—this intelligent device allows administrators to schedule bell rings accurately and reliably without any manual involvement.
Whether it’s a regular school day, examination schedule, or cultural program, the UB‑501 handles it all with precision and flexibility. Its powerful internal controller, audio playback system, and calendar-based features make it an ideal choice for schools, coaching centers, temples, and other organizations that need structured time announcements.
Why UB‑501 Is the Top Choice for Schools
The UB‑501 School Bell System comes packed with advanced scheduling and playback features tailored for Indian institutions. It lets you define up to 24 unique schedules, accommodating regular school days, seasonal shifts, or examination routines.
You can schedule up to 50 bells per day, ideal for institutions with multiple shifts. Need to cancel bells on national holidays or Sundays? No problem—this device supports 120 programmable holidays per year and can automatically adjust for weekly offs.
Each day of the week can have a separate schedule, so Monday’s bells can differ from Friday’s—making it incredibly flexible. And yes, it supports seasonal modes like Summer, Winter, and Exams with just a few clicks.
Audio Flexibility and Playback Power
The UB‑501 comes preloaded with 53 bell tones and audio messages, including female voice announcements (like “Lunch Break,” “Class Over,” “School Time Over”), temple bells, and traditional gong tones.
Want to customise it even further? Simply insert a Micro-SD card (up to 32GB supported) and upload your own MP3, WAV, or WMA audio files. This makes it perfect for schools that want to play custom messages, prayers, or musical tones.
The system connects easily to any external amplifier or speaker system using a standard AUX cable, so integration with your existing audio setup is seamless.
Advanced Power Management and Automation
The UB‑501 goes beyond just playing audio—it also features built-in power control for your amplifier. The device automatically powers the amplifier on and off during scheduled bell times using a 220V, 8A relay, helping conserve energy and reduce human intervention.
Its durable, compact design fits into almost any control room or principal’s office. Installation is simple—no IT team required.
