Intrusive announcements in the event of an emergency are not an option, they are a necessity. That’s why our Mobile High Power Speaker Arrays (MSA 3100 Series) are designed for wide-area mass notification, covering large areas with crisp, intelligible voice, tone and siren warnings. The MSA is a portable field notification unit for tactical operation, forward unit deployments, disaster management and temporary events. The mobile system requires minimal operator set-up and can be rapidly deployed before, during and after a disaster. The MSA can be moved with any military or civilian vehicle and airlifted. The MSA can operate autonomously or as an integral component of the WAVES (Wireless Audio Visual Emergency System) MNS or TACWAVES (Tactical WAVES) portable alerting system.

In stand-alone mode, it delivers up to 128 pre-recorded messages stored in its own memory and tones generated by its digital tone generator, including the standard FEMA public warning tones with optional Local Messaging Device (LMD)hardware. With noise-canceling microphone, a local operator can deliver live voice messages.

When connected to a WAVES Mass Notification System, the MSA delivers announcements originating from the WAVES Base Station via digital, Frequency Hopping Spread Spectrum (FHSS) technology @ 2.4 GHz. The MSA is also capable of activating voice and tone messages stored within the MSA unit.
