What We Install & Service

TCG is Michigan's go-to certified installer for AtlasIED GlobalCom — the platform trusted in airports, hospitals, government buildings, and K-12 districts for network-distributed audio, emergency alerting, and mass notification.

IP-Based PA System Design & Installation

Network-distributed audio using AtlasIED GlobalCom GCK — scalable zones, priority routing, and digital audio clarity from the equipment room to every speaker in the facility.

Emergency Mass Notification

Life-safety compliant emergency notification integrated with fire alarm panels, intrusion detection, and active shooter response systems. Tested, documented, and certified at commissioning.

Background Music & Zone Audio

Separate audio zones for background music, routine announcements, and override alerting. Lobby, production floor, cafeteria, and outdoor zones all managed from one interface.

PA System Upgrades & Cutovers

Legacy analog PA systems replaced with modern IP infrastructure — with carefully planned cutovers that keep the facility communicating throughout the transition. We've done it at DTW.

Ongoing Service & Repair

PA system troubleshooting, speaker replacement, amplifier repair, and system re-programming. Available through ServicePAK for 24/7 priority response.

K-12 & Campus Intercom Systems

Bell scheduling, classroom intercom, and mass notification integrated into a single IP-based platform. Safety-compliant and E-rate eligible for Michigan school districts.

Case Study — Detroit Metro Airport

Major PA System Upgrade — DTW Evans Terminal

TCG completed one of the smoothest cutovers in our history: a major public address system upgrade at Detroit Metro Airport's Evans Terminal using AtlasIED GlobalCom GCK, delivering network-distributed audio for public address, local paging, background music, and public safety utilities — on time, on budget, and with zero disruption to passenger operations.
