Acoustic Technology, Inc. (ATI Systems)
Founded in 1981, ATI Systems is a pioneer in emergency notification and mass warning systems, with over 5,000 systems deployed globally across military, campus, industrial, and community environments.
ATI’s flood early warning solutions bring proven outdoor siren technology — built for durability, longevity, and reliability — to Texas communities facing flash flood risk. ATI systems are engineered to operate during the most severe weather events, integrating with NOAA National Weather Service, IPAWS, and third-party alert platforms to ensure communities receive timely, actionable warnings when every minute counts.
ATI’s Next-Generation HPSS sirens are purpose-built for long-term field reliability — featuring a modular design with fewer components, simplified maintenance procedures, and a minimalist architecture that reduces failure points and extends service life, directly supporting TWDB best management practice requirements for sustainable FEWS operations.

How ATI Systems Supports the FEWS Lifecycle
The Texas Water Development Board’s FEWS Guidance Document identifies four stages for developing an effective Flood Early Warning System. ATI Systems provides products and services that address every stage of this lifecycle.
1. Planning
ATI’s acoustic design and site analysis services help communities establish goals, identify optimal siren placement locations, and develop a system tailored to local flood risk — incorporating TWDB FEWS best practices.
2. Financing
ATI Systems assists communities in understanding project and O&M costs, supports grant documentation needs, and provides FEMA and TWDB FIF-eligible equipment suited to community budgets of all sizes.
3. Deploying
ATI’s turnkey approach covers engineering, procurement, installation, testing, commissioning, and personnel training. Project timelines vary based on site conditions, communications requirements, and permitting — ATI will provide a project-specific schedule as part of the engineered solution.
4. Managing
Post-installation, ATI provides warranty coverage, ongoing maintenance, remote monitoring via MassAlert® software, system upgrades, and support — ensuring long-term reliability critical to TWDB best management practice compliance.
TWDB Flash Flood Warning Siren Guide (January 2026): SB 3 requires all outdoor warning siren systems to include backup power, regular functionality testing, and integrate all components essential to system function. ATI systems are engineered to meet these specifications, including solar backup power options and remote self-test capabilities.
Meeting SB 3 Siren System Requirements
Texas SB 3 (signed September 5, 2025) requires municipalities and counties in designated flash flood-prone areas to install outdoor warning siren systems meeting TWDB best management practices. Here is how ATI Systems addresses each core requirement:
Outdoor Warning Siren Coverage
Backup Power Source
TWDB’s Flash Flood Warning Siren Guide requires all systems to include a backup power source to maintain full operability during the power outages most likely to accompany severe flooding events.
ATI Solution: Next-Gen HPSS units include battery backup providing >7 days standby and 60 minutes of continuous full-power activation without AC power. Batteries are trickle charged with AC power or solar panel.
Hydrological Sensor Integration
TWDB FEWS guidance requires data collection components including water level sensors, rain gauges, and stream gauges as essential elements of the warning system. Per SB 5, flood gauges and all components essential to system function are eligible for grant funding.
ATI Solution: MassAlert® integrates with radar water level sensors, rain gauge sensors, and pressure transducers. Sensor threshold events automatically trigger siren activation — providing real-time, data-driven flood alerts without manual intervention. Compatible with ALERT/ALERT2 protocol networks and third-party sensor platforms.
Manual & Automatic Siren Activation
Effective FEWS require both operator-initiated activation for known events and automated activation when sensor thresholds are reached — particularly for flash floods that develop faster than personnel can respond.
Reliable Communication & Control
Systems must support reliable remote activation and monitoring, particularly for rural Hill Country locations with limited infrastructure, variable cellular coverage, and potential power outages during flood events.
Regular Functionality Testing
TWDB best management practices require outdoor warning siren systems to be regularly tested for functionality and to generate records of test results to ensure readiness when a flood event occurs.
NWS, IPAWS & CAP Integration
Effective FEWS must coordinate with the National Weather Service for flood alerts. TWDB guidance strongly encourages NWS collaboration. SB 3 systems must be capable of responding to official weather warnings for designated flash flood-prone areas.
Warranty, Maintenance & Longevity
TWDB guidance requires O&M budgets at 10–15% of initial costs annually, with equipment engineered for 10–15+ year lifespans, documented maintenance schedules, and qualified support staff familiar with system components.
