Public Address and Paging Systems — Michigan - Michigan's Cabling Contractor

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. Healthcare facilities and hospital paging systems require reliable, code-compliant solutions — GlobalCom delivers on both.

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.

Frequently Asked Questions

What is AtlasIED GlobalCom and why does TCG recommend it?

AtlasIED GlobalCom is a commercial-grade IP-based PA platform used in airports, hospitals, schools, and large commercial facilities. TCG is a certified GlobalCom installer, which means our installations qualify for full manufacturer support, system warranties, and proper commissioning documentation. It's also the platform we've used at DTW — one of the most demanding PA environments in Michigan.

Can my existing speakers be reused with a new IP-based PA system?

In many cases, yes. Existing speaker wiring and speakers can often be retained when upgrading from analog to IP-based PA. TCG performs a full system assessment to identify what can be reused and what needs replacement before scoping the upgrade.

Is your PA work compatible with fire alarm integration?

Yes. TCG designs PA systems with life-safety integration in mind — fire alarm relay inputs, priority override logic, and NFPA-compliant emergency tone capability. All integrations are tested and documented at commissioning.

Do you provide E-rate eligible PA installations for Michigan schools?

Yes. IP-based intercom and PA systems installed by TCG can qualify under FCC E-rate Category 2. We work with school districts and their E-rate consultants to scope projects appropriately for the application.

What does a PA system commissioning involve?

Commissioning includes end-to-end system testing — every zone, every speaker, every priority level verified. We document all zone routing, test all emergency functions including mass notification and fire alarm integration, and deliver a commissioning report with your closeout package.

Do you install wireless paging systems?

Yes — in addition to IP-based wired PA infrastructure, TCG evaluates wireless paging alternatives including Spok nurse-call and alphanumeric paging, Zetron mission-critical wireless paging, and Wi-Fi-based IP paging over existing network infrastructure. Many facilities use a hybrid approach — wired PA for overhead announcements and wireless pagers for personal notification. We'll assess your environment and recommend the right mix.
