With the constant need to alert and inform, the HyperSpike® MA-1 is a battle-tested and battle-proven, 360° Mass Notification System. With an acoustic output of 143 dB, the lightweight MA-1 high power speaker broadcasts crystal clear voice messages and tones to a 7 sq mile area; making the MA-1 the life safety speaker of choice.

Housed in an all-composite, waterproof UV-resistant enclosure, the battle-tested MA-1 has become the trusted mass notification system for the US military’s forward operating bases in Afghanistan and Iraq.  Ideal for rapid deployment, the MA-1 system can go from its road case to fully operational in under five minutes.

The MA-1 is the “clear” choice for alerting and facilitating a response before, during, and after an event!
