The Challenge
Leichhardt Public School in Sydney's Inner West is one of NSW's oldest public schools. When their entire PA and bell system failed, the school faced an immediate safety risk — no working fire drills, lockdown announcements or school-wide communication. The situation required urgent intervention.
MVT's site inspection revealed the full extent of the problem: a failed Yamaha matrix that no longer passed audio, budget low-impedance speakers unsuitable for distributed public address use, aged prosumer amplifiers with more than half non-functional, inappropriate low-impedance speaker cabling causing coverage drop-off, failed AV media converters stopping audio transmission between buildings, and amplifiers installed outdoors in non-weatherproof housings — an unsafe installation by any standard. The infrastructure was beyond repair. A complete redesign was required.
Project Goals
Full school-wide communication was restored promptly after a rapid-response deployment. The school now meets current NSW Department of Education standards for emergency paging and evacuation communication. Every student hears announcements clearly across all indoor and outdoor zones from a single touchscreen interface.
The scalable Dante-networked architecture supports future expansion including additional zones and video paging integration. The MVT bell management software has since been deployed across multiple additional NSW Catholic and government schools, with each site benefiting from consistent design and centralised support capability.
