Remote Terminal Unit (RTU)
The versatile Remote Terminal Unit can interface a wide variety
of inputs and outputs to the ATI control system. Input from devices
such as wired or wireless push buttons, sensors and fire panels
can be configured to trigger system activations. The RTU outputs
can control a variety of external units during an activation. Examples
include traffic light control, strobe lights, gate control units,
radio repeaters and message signs. The RTU can also put out an audio
signal to provide alert messages or live voice to external PA systems
or radios.
