Maximize Indoor Acoustic Coverage in an Emergency
ATI’s Indoor Speaker Unit (ISU) delivers reliable alert tone notification, pre-recorded messages, and public address for emergency situations in any indoor environment. It is equipped with 400 Watts of audio output power, with the optional upgrade to 800 Watts. The ISU 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 as a standalone using the Local Operating Console (LOC) option.
Indoor Speaker Unit (ISU) serves as the core component of the indoor notification system by utilizing a combination of low-power ceiling and wall speakers for hallways and common areas, medium-powered horn speakers for larger rooms and open spaces, and strobes and LED signage for visual alerting. This combination ensures that both audible and visual notifications reach all occupants effectively, making it ideal for environments where clear communication is critical.
High-Power Audio Output:
Equipped with a 400W amplifier (with an optional 800W upgrade), the ISU drives multiple zones of speakers and strobes, providing excellent sound coverage for any indoor environment.
Reliable and Secure:
Supports multiple communication paths, including UHF/VHF RF, IP, Ethernet, twisted pair, and more. Advanced security features include SSL/TLS encryption and message coding to prevent unauthorized activations.
Multi-Zone Alerting:
Capable of managing several zones of audible and visual alerts, making it ideal for large facilities with multiple areas requiring distinct alerts.
Seamless Integration:
Easily integrates with external systems such as Public Address (PA), Fire Alarm Control Panels (FACP) etc., for a unified indoor notification solution.
Flexible Control Options::
The ISU can be operated and controlled remotely from a Central Control Station or locally using a Local Operating Console (LOC), providing flexibility for diverse operational needs.
Backup Power Support:
Includes a built-in battery backup, ensuring continuous operation during power outages, with up to 48 hours of standby time and 60 minutes of full-power activation.
