777 Photo and/or Graphic Element

There are two detector loops in each engine nacelle. Each loop can detect an engine overheat or fire. Normally, both loops must sense a fire or overheat condition before the crew is alerted. If a fault is detected in one loop, the system automatically switches to a single loop operation. If a fault develops in both detector loops of an engine nacelle, there is no fire or overheat detection and an EICAS message is displayed.
