What is a Voice Announcement Bell System?

Bell + PA System.
One Device.

Smart School 360 is a voice announcement school bell system manufactured by Cortek Electro in Pune, India. It combines a fully automated programmable bell controller with a built-in PA (public address) system that allows the principal or any authorised staff member to make live voice announcements to the entire campus or to specific zones. The system includes two microphone inputs — one typically placed in the principal's office and one in the staff room. Announcements can be made to all zones simultaneously, or to selected zones only by manually choosing the active zone on the touchscreen before speaking. This enables targeted communication — calling a specific section without disturbing the rest of the campus. In addition to live announcements, the system plays pre-recorded audio including national anthem, school prayer, meditation music, water bell tones, and custom MP3 files uploaded by the school.

Use Cases

When Schools Use
Voice Announcements

Emergency Alerts

Student Summoning

Call a specific student or teacher to the office without disrupting the entire school. Broadcast to one classroom zone while keeping all other zones silent.

Schedule Changes

Announce last-minute timetable changes, assembly reminders, or exam instructions directly to all teachers and students without needing to send notices class by class.

Morning Prayer & Assembly

Automatically play the national anthem, school prayer, or motivational music at the programmed time — no staff action required. Supports custom audio upload.

Safety Drills

Use the pre-recorded or live announcement to conduct fire drills, earthquake drills, and safety exercises. The emergency siren can be triggered instantly from the touchscreen.

FAQ

Voice Announcement Bell
Questions Answered

Zone selection is done manually on the touchscreen before you make an announcement — you choose which zone is active, then pick up the mic. Zones are physically defined by how the speakers are wired during installation. Most schools wire by floor or section. If you need a zone that covers just two or three specific classrooms, we design it that way during the site survey.
Yes, and it should. Once you have selected the active zone on the touchscreen and pick up the mic, your voice takes priority over everything — playing bells, scheduled audio, all of it. When you put the mic down, normal scheduling resumes automatically. The zone selection is the one manual step required before speaking.
Yes. Upload MP3 files and schedule them like any other bell event. Common uses: national anthem at 7:30 AM, school prayer, meditation music at 1:00 PM, custom assembly music for Independence Day and Republic Day. You can also assign different audio files to different zones — assembly music plays in the hall, a softer chime plays in classrooms. We handle the initial audio uploads during installation. After that, you manage files from the touchscreen via a USB drive.
Depends on the model. Z1 covers up to 120 metres of speaker wiring with 8 speakers. Z2 covers 240 metres with 16 speakers. Z3 covers 360 metres with 24 speakers. Speaker wattage matters too — 15W for individual classrooms, 30W for corridors, 60W for the assembly hall or playground. During the site survey, we map which wattage goes where based on room size and ambient noise. A playground speaker next to a 15W classroom speaker sounds completely different even at the same volume setting.
All three models include the PA system and dual microphone inputs as standard — it's not an add-on. Z1 is ₹35,500, Z2 is ₹59,000, Z3 is ₹79,000. Installation included. A school that only wants a basic bell timer and a school that wants full PA capability with emergency siren pays the same price for the same device. The features are all there. You use what you need.
