With the constant need to alert and inform, the HyperSpike® MA-2 is a UL1480A, Class I, Division 2 Hazardous Location certified, 360° Mass Notification System. With an acoustic output of 148 dB, the MA-2 high power omni-directional sound speaker broadcasts live and pre-recorded voice commands and tones over a 12 square mile area; making the MA-2 the life safety directional sound speaker of choice.

Leading the industry in voice intelligibility, the MA-2 speaker design achieves an exceptional STI rating of 0.91 out of 1.0; ensuring commands are clearly transmitted and heard, even in high noise environments.
