ATI’s ISU combines our highly configurable RTU with 400 Watts (optional upgrade to 800 Watts) of audio output power for the delivery of reliable alert tone notification, pre-recorded messages and public address in emergency situations. It is capable of driving multiple zones of audible and visual alerts such as speakers and strobes. The unit is monitored, controlled, and activated by an ATI central control unit, such as the REACT5000, or can operate standalone using the LOC option.*
