Alertus Outdoor Notification

Alertus Technologies provides cost-effective, innovative outdoor notification solutions that can enhance or integrate with your existing giant voice system. Wide-area mass notification systems are generally installed to provide real-time information to outdoor areas. Pre-recorded messages often fall short of providing people with specific information. Likewise, an unrehearsed live voice is onerous and can be challenging and stressful in a crisis situation. Customers have found that when using live public address systems, communication often comes across unintelligible when amplified due to several factors including accents, voice inflections, fast or slow cadence, or improper enunciation. These factors can lead to a garbled message, creating more confusion and chaos in the event of an emergency.

High Power Speaker Arrays

Alertus offers breakthrough text-to-speech technology embedded in a high power speaker array (HPSA) to overcome these challenges. Alertus can override your existing outdoor HPSA or design a new system to cover your campus, base, or facility outdoor areas with siren tones and clear voice messages. Alertus outdoor self-amplified high power speakers and low powered self-amplified speakers are also available should a HPSA not be suitable for your location.

HPS 100 

The Alertus HPS100 is a standalone, compact, self-amplified electronic speaker that delivers clear voice messaging and siren tones for emergency notification. The HPS100 provides comprehensive audible coverage to both your indoor and outdoor high-occupancy areas to ensure you reach everyone in an emergency.

Text-to-Speech Technology

The Alertus text-to-speech (TTS) module makes it easy to link voice systems with Alertus Beacons® mounted in buildings without voice infrastructure. The Alertus TTS module enables emergency communications to be connected with multimodal mass notification components such as personal messaging. When issuing an alert notification, dispatchers may choose to use spoken output in addition to the standard activation options such as strobes and sirens. The Alert Beacon then passes the message text to the TTS module, and the spoken message plays automatically through the connected audio speakers.

Integration Capabilities

Alertus can help you determine the correct number and location of outdoor speakers and can perform a preliminary acoustical study to predict the sound coverage of each speaker. We take into account the areas that you would like covered with clear voice, topographical changes, vegetation, building heights, ambient noise, and several other factors to optimally place the speakers. Alertus also integrates and is compatible with a number of outdoor mass notification speaker options, including but not limited to HPSA towers from ATI, Whelen, Federal Signal, American Signal, and Cooper Waves.

Before, with sirens and public address, you could only do pre-recorded voice messages. Now, with Alertus’ outdoor notification interface, we can do text-to-speech based on the situation, which is so valuable to us.
