Problems Solved

  • Inflexible System
  • Limited Budget
  • Safety Concerns
  • Unreliable Hardware


  • PA System: Old analog PA system became increasingly unreliable and difficult to repair.
  • Teachers and students couldn’t hear emergency announcements in loud classrooms.
  • The safety committee couldn’t implement pre-recorded scripts.


With Carina, we got a comprehensive platform with a fully digital paging system, synchronized clock and bell scheduler, classroom intercom, and emergency notification that’s future-proof. – Gerry Dawson, Technology Director


Carina, made by Wahsega, provided the most cost-effective solution since he could reuse the existing ethernet cabling, lowering his installation costs by almost 90%.

IP Displays, providing visual and audio messages, were installed in every classroom to address dynamic noise levels.

The school’s safety committee recorded safety announcements and implemented them in Carina for triggering at a moment’s notice.


With Wahsega devices in place, you just unplug them, take them into the building in the new classroom, plug them in, and you haven’t lost one dime. – Gerry Dawson, Technology Director
