Automated Outdoor Flood Warning Siren & Mass Notification System
High-powered audible sirens, voice instructions, flashing beacon lights, and AwareShield cloud intelligence — delivering instant, loud, and clear flood warnings to communities and infrastructure sites the moment water levels become dangerous.
Early Detection Is Critical — Communities Need Warning Before Floods Become Deadly
Flood conditions can escalate from manageable to life-threatening in minutes. When water rises faster than communications spread, communities are left without the warning time they need to protect lives, evacuate, and secure infrastructure.
Timely, loud, and unmistakable warnings give residents and emergency responders the lead time that saves lives. AWARE Outdoor Warning Systems replace slow, manual alert processes with fully automated, sensor-triggered mass notification — activating sirens, voice instructions, beacon lights, and sending SMS and email notifications the instant predefined flood thresholds are exceeded.
Phone trees and manual protocols introduce critical delays. By the time a warning reaches the public, flood conditions may already be dangerous.
Without high-powered outdoor sirens, people in flood-prone areas receive no immediate, unmistakable alert — relying on cell service or word of mouth.
Standalone sirens without sensor integration cannot activate automatically — creating dangerous gaps during rapid onset flood events.
From field sensors to cloud platform to siren activation — AWARE connects detection to notification in seconds.
AwareShield — The Command Center Behind Every Warning
At the core of every AWARE Outdoor Warning System is AwareShield — a centralized, web-based software platform that brings together real-time data visualization, alarm activation, instant messaging, and hydrological forecasting in a single, agency-ready interface.
S.H.I.E.L.D. ⛊ makes it simple for emergency managers to monitor conditions across an entire sensor network, configure automated alert thresholds, activate sirens remotely, and broadcast notifications — all from one screen. Whether your agency manages two sites or two hundred, S.H.I.E.L.D. ⛊ provides the situational awareness and control to act fast when it matters most.
Learn More About S.H.I.E.L.D. ⛊
Monitor water levels, rainfall, and environmental conditions across all sensor nodes on a live web dashboard accessible from any device.
Configurable thresholds automatically trigger sirens, voice instructions, beacons, SMS, and email alerts the instant flood conditions are detected.
Simultaneously alert dispatch, public works, and the public via SMS, email, siren, beacon, and direct integration into public flood warning websites.
Leverage sensor trend data and predictive analytics to anticipate rising conditions before thresholds are reached.
Engineered for Reliable, Autonomous Public Warning
Every component is selected and integrated for continuous, dependable performance in real-world emergency environments.
High-Powered Audible Sirens & Voice
Federal Signal UltraVoice siren arrays deliver from 800 to 3,200+ watts of scalable omnidirectional output — reaching residents outdoors, in vehicles, and inside structures across a wide area with both audible tones and pre-recorded voice instructions.
Flashing Beacon Lights
High-visibility warning beacons provide a critical visual alert — essential for noisy environments, people with hearing impairments, and low-visibility storm conditions where audible warnings alone may be insufficient.
Automated Sensor-Triggered Activation
Water level and rainfall sensors continuously monitor conditions. When predefined thresholds are exceeded, S.H.I.E.L.D. ⛊ activates sirens, beacons, and all notification channels automatically.
S.H.I.E.L.D. ⛊ Cloud Control
Centralized web platform for real-time monitoring, remote siren activation, configurable alert thresholds, hydrological forecasting, and multi-agency notification — all in one dashboard.
Solar Power & Off-Grid Operation
Federal Signal PVS240W solar options enable fully autonomous siren deployment — eliminating costly utility trenching, supporting remote sites, and maintaining operation during grid power outages.
Rugged Field-Proven Construction
All outdoor hardware is built for extreme environmental conditions — wind loads up to 170 mph, repeated flood exposure, and harsh climates — ensuring reliable performance when communities need it most.
From Rising Water to Public Warning — Automatically
AWARE integrates continuous field monitoring with instant multi-channel public notification in four seamless steps.
Monitor Water & Weather Conditions
AWARE sensor nodes continuously track water levels, rainfall, and environmental conditions at streams, rivers, floodplains, and road crossings — transmitting data in real time to S.H.I.E.L.D. ⛊.
Detect & Analyze Threshold Conditions
S.H.I.E.L.D. ⛊ analyzes incoming sensor data against agency-configured flood thresholds. When conditions exceed predefined action levels, the system immediately initiates the alert response sequence.
Activate Sirens, Voice, Beacons & Alerts
High-powered sirens broadcast audible tones and pre-recorded voice instructions. Flashing beacons activate automatically at the field site, while S.H.I.E.L.D. ⛊ sends SMS, email, and statewide DOT notifications to all configured recipients.
Monitor, Respond & Document
Emergency managers monitor the evolving situation on the S.H.I.E.L.D. ⛊ dashboard, coordinate response actions, and access historical data for after-action review and reporting.
