Remote Terminal Unit

Simple Integration to Existing MNS Components and Peripherals

Innovating Emergency Alert Systems (EAS)

ATI’s versatile Remote Terminal Unit networks a wide variety of 3rd party input and output devices with an ATI central control unit, such as the REACT5000. Input from devices such as wired or wireless push buttons, sensors, and fire panels can be configured to trigger system activations. The RTU output signals can control a plethora of devices such as traffic light controllers, strobe lights, gate control units, radio repeaters, and digital message signs. In addition, the RTU can supply line-level audio to provide audible alerts or live voice to external PA systems or radios.
