How many ITT fire indications are there when a fire is detected?

When a fire is detected in the Embraer Regional Jet (ERJ) systems, there are two ITT (Inter Turbine Temperature) fire indications triggered in the cockpit. This dual indication system serves to enhance safety by providing redundant alerts to the flight crew.

The first indication typically appears as an alarm, notifying the crew of an emergency situation. The second indication often manifests as a visual cue on the engine monitoring display, signaling which engine the issue is associated with. This dual alert system is crucial as it helps ensure that pilots have a comprehensive awareness of potential fire risks, enabling them to respond quickly and effectively to protect both the aircraft and its occupants.
