frequent trouble alarm in Det-Tronics system


Thread Starter



in Det-Tronics fire detection system that contains an Eagle Quantum Premier controller and LON network which consist of three Det-tronic X2200 fire detectors. we had a frequent trouble alarm 'Oi Fault' in one of X2200 detectors. following the instruction manual we noticed that the detectors must be cleaned periodically (in Oi viewing window), but the trouble seems not fixed. anyone had such problem experience before? or suggestion? thanks in advance
