We design, install and upgrade school bell systems, PA speakers, lockdown alerts and emergency announcement systems for Melbourne schools. From daily bells to evacuation messages, we make sure staff can communicate clearly across classrooms, playgrounds and common areas.
A school PA system is the speaker and announcement system used across a school campus. It can include daily bell tones, office paging, classroom announcements, playground speakers, lockdown alerts and evacuation messages.
