Mass Notification & Giant Voice
Installation-wide mass warning including outdoor giant-voice siren/PA arrays and indoor/desktop/mobile alerting integrated to AtHoc and the DoD Mass Warning & Notification System (MWNS). The command-directed, life-safety emergency communication mandated by UFC 4-021-01 — and the alerting spine that ties video, access, gunshot and C-UAS into one fabric.
- Outdoor giant-voice siren and high-power speaker array design
- Indoor mass notification (speakers, strobes, ADA visual, digital signage)
- Integration to AtHoc / MWNS and INWS (AFI 10-2501 / service guidance)
- Triggering from gunshot detection, IDS and weather/CBRN inputs
Capabilities engineered in, not bolted on.
Intelligible Giant Voice
Outdoor siren and high-power speaker arrays designed against UFC 4-021-01 acoustic models, so the warning is heard and understood across the whole installation footprint — not just loud, but intelligible at the fence line.
One Alerting Spine
AtHoc and DoD MWNS tie outdoor giant voice, indoor speakers and strobes, desktop pop-ups and mobile alerts into a single command-directed message that reaches every channel at once.
Auto-Triggered Warnings
Gunshot detection, intrusion alarms, and weather or CBRN inputs fire pre-approved templates automatically — collapsing the time between a detected threat and a population-wide alert.
Mass Notification & Giant Voice that holds up to scrutiny.
Installation-wide mass warning including outdoor giant-voice siren/PA arrays and indoor/desktop/mobile alerting integrated to AtHoc and the DoD Mass Warning & Notification System (MWNS). The command-directed, life-safety emergency communication mandated by UFC 4-021-01 — and the alerting spine that ties video, access, gunshot and C-UAS into one fabric.
We lead with engineering and compliance: the system is designed to standard, installed on genuine warrantied hardware, and documented so it clears procurement and accreditation the first time.

Standards & compliance
Every mass notification & giant voiceengagement is delivered on TAA / NDAA Section 889-compliant hardware, with country of origin documented and a compliant equivalent quoted whenever a unit isn't designated — engineered to UFC 4-021-01, AtHoc / MWNS, ADA / IBC where they apply.

Vendor-neutral — the right compliant line for the mission.
The alerting spine for the whole installation
Mass notification only works when every layer speaks with one voice. We design outdoor giant-voice arrays and indoor alerting to UFC 4-021-01 coverage and intelligibility standards, then integrate them to AtHoc and DoD MWNS so a single command-directed message reaches sirens, speakers, strobes, desktops and mobile devices simultaneously. The same spine accepts automated triggers from gunshot detection, intrusion and weather/CBRN sensors, and routes through ECC and dispatch consoles with managed message templates.
- UFC 4-021-01 intelligibility and coverage acoustic modeling
- Unified AtHoc / MWNS delivery to every channel at once
- ADA visual notification, strobes and digital signage indoors

Mass Notification & Giant Voice — frequently asked
What does mass notification & giant voice include?
Installation-wide mass warning including outdoor giant-voice siren/PA arrays and indoor/desktop/mobile alerting integrated to AtHoc and the DoD Mass Warning & Notification System (MWNS). The command-directed, life-safety emergency communication mandated by UFC 4-021-01 — and the alerting spine that ties video, access, gunshot and C-UAS into one fabric. Core deliverables include outdoor giant-voice siren and high-power speaker array design; indoor mass notification (speakers, strobes, ada visual, digital signage); integration to athoc / mwns and inws (afi 10-2501 / service guidance).
Is your mass notification & giant voice TAA and NDAA Section 889 compliant?
Yes. Every mass notification & giant voice engagement is delivered on TAA / NDAA Section 889-compliant hardware with country of origin confirmed at the SKU level, and we quote a compliant equivalent whenever a unit isn't designated. Relevant standards: UFC 4-021-01, AtHoc / MWNS, ADA / IBC.
Who is mass notification & giant voice for?
Mass Notification & Giant Voice is built for DoD installations, federal campuses, SLED, critical infrastructure. We size and document the system to that environment's threats, compliance posture and budget.
Do you handle the whole lifecycle, or just install?
One accountable team owns it end to end — assess, design, integrate, monitor and maintain — so accountability never falls through a hand-off. Maintenance and SLAs keep mass notification & giant voice compliant and operational over time.
