On climbout we received an E2 FIRE DET FAIL EICAS message. Decided to [advise ATC] and return to ZZZ due to the fact we do not know why the fire loop had failed. Had fire rescue meet us on the ground and inspect #2 engine for anomalies. Taxied to the gate and deplaned passengers. Faulty fire loop in the number 2 engine.Other than routine mx; this was an unlikely event and needs to be handled by occasion.
On our climbout as we were passing through FL230; we received an EICAS MSG 'E2 FIRE DET FAIL'. We referred to the QRH and followed the listed procedure. Since we had a fire detection failure for E2; for the interest of passenger safety and [airline] brand; I determined the best course of action for us would be to return back to ZZZ. Center immediately gave us vectors back to the airport and we had an uneventful approach and landing on runway. Once we landed and exited the runway; CFR did a thermal and visual inspection of the engines and followed us back to the gate. Once we arrived at the gate; we were met with gate agent managers; who helped us deplane the passengers safely into the terminal. I also wrote up the maintenance discrepancies in the AML.
