Military Mass Notification Systems

Giant Voice Alerting Systems

ATI’s Mass Notification Systems (MNS), often referred to as Giant Voice (GV), are critical for alerting all base personnel to threats and directing the immediate actions required to mitigate loss of property and life. UFC 4-021-01 requires MNS for providing real-time information to personnel located on military installations.

ATI Systems is an industry-leading manufacturer of wireless Mass Notification Systems for military applications. ATI’s DoD-approved MNS is the most effective and efficient real-time means to notify base personnel of threats and the appropriate response to those threats.


ATI’s integrated and stand-alone Giant Voice Mass Notification Systems (MNS) provide DoD installations with the ability to rapidly communicate both outside and inside of buildings on a base or facility.

With the push of one button, the ATI MNS delivers clear and intelligible voice commands with actionable instructions across various platforms, including:

  • Outdoor and Indoor Voice and Tone
  • Public Address
  • Mobile Giant Voice Speaker Trailers
  • Telephone Alerting
  • Network Alerting Systems.

All components activate simultaneously, saving valuable manpower and time when you need to alert quickly and urgently.

Command Post operators use the Giant Voice to initiate real-time notifications of threats to all system components over encrypted wireless communications. The notifications are then broadcast to the outdoor area of the base using GV, in buildings using ATI’s Indoor MNS, and also over telephone, SMS/text, email, desktop popup, and Web/RSS using ATI’s Network Alerting capabilities.

Operators are often required to implement multiple system activations while under duress; therefore, ATI’s “one button approach” to outdoor, indoor, and network alerting simplifies initiating quick and accurate threat notifications.

The MNS can broadcast (but is not limited to) attack alerts, watches, warnings, severe weather alerts, evacuation routes, and other alerting information. All broadcasts meet DOD and federal warning requirements.


ATI has a complete family of products that deliver a turnkey system solution for outdoor/indoor base notification. ATI has considerable experience working with DOD and military customers to provide best-in-class military alerting systems.


ATI’s Giant Voice (GV) outdoor component is the High-Powered Speaker Station (HPSS), which can be mounted on poles or structures. HPSS speakers can also be mounted on a trailer for easy deployment to areas of the base requiring temporary alerting capabilities. The HPSS provides alert tones, live voice broadcast, and pre-recorded audio messages, including exercises, drills, taps, reveille, the national anthem, etc.

To create the appropriate level of sound output and maintain voice intelligibility, multiple poles and speaker stations or trailers are positioned in specific locations throughout the base. The speaker heads are designed to allow 90, 180, 270 or 360-degree coverage, and can be tilted downward to control sound propagation. ATI is renowned for providing the best voice intelligibility available in the market today.


ATI provides full indoor alerting coverage for all buildings on base. Our indoor voice systems interface with existing or new construction PA systems and/or fire alarm control panels to provide superior indoor alerting.


Pricing is based on our GSA schedule, offering extremely competitive prices on our products and services. With systems that are fully scalable and flexible, we can develop a complete Integrated Warning System up front, or phase in different components over time, depending on your budgetary needs. All systems are designed to meet the Unified Facilities Criteria (UFC) 4-021-01 for the Design, Operation and Maintenance of Mass Notification Systems and IPAWS requirements.
