Airports & Aviation

Airports are the most complex environments ITS Design Team serves. A single terminal combines operational paging (boarding calls, gate changes, security announcements), automated messaging (FIDS-driven announcements), fire alarm integration (voice evacuation for terminal areas), and mass notification (campus-wide emergency alerts across terminals, aprons, and ground operations). These systems must coexist on shared infrastructure without interference, with absolute priority for life safety messaging.

ITS has designed PA and life safety systems for major Canadian airports, including Calgary International Airport and Pearson International Airport (Terminal 3). The work spans Q-SYS DSP platform design, fire alarm–PA integration for code-compliant voice evacuation, unified passenger information systems with automated paging and FIDS integration, and multi-zone architectures covering terminals, concourses, lounges, and ground-side operations.

What Makes Airport PA Different

Airport environments present unique challenges: high ambient noise from crowds and HVAC systems, large open concourse spaces with challenging acoustics, continuous operational announcements that must not interfere with emergency messaging, and regulatory requirements from both building codes and aviation authorities. The PA system must deliver intelligible speech in every zone while managing dozens of concurrent announcement queues with strict priority hierarchies.

ITS designs airport PA as a unified platform — not a collection of independent systems bolted together. The fire alarm, operational paging, automated messaging, and emergency notification all share a single DSP architecture with coordinated zone maps, priority management, and failover behaviour.
