With the constant need to alert and inform, the HyperSpike® MA-1 is a UL 1480A listed and CID2 Hazardous Location certified, 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 4 sq mile area; making the MA-1 the life safety speaker of choice.
