A、 If an engine overheat/fire detector can not operate, the engine and APU fire alarm unit alternatively changes to single loop operation. In the single loop module, only one loop must check the engine and APU fire detection module for an overheat or fire condition to give the alarm condition.
B、 If an engine overheat/fire detector fails to operate, the engine and APU fire detection module automatically changes to single loop operation. In the single loop mode, only one loop must detect an overheat or fire condition for the engine and APU fire detection module to give the alarm condition.
C、 If an engine overheat/fire detector is inoperative, the engine and APU fire detection module automatically changes to single loop operation. In the single loop mode, only one loop must detect an overheat or fire condition by the engine and APU fire detection module for the alarm condition.
