OCEM LOYRA Individual Light Control & Monitoring
Per-fixture monitoring over the 6.6 A series loop.
LOYRA is OCEM's individual light control and monitoring platform. A smart module paired to each isolation transformer communicates over the existing series cable back to an AFL-Controller, giving tower operators per-fixture state, intensity step, cumulative burn hours and fault codes. LOYRA supports stop-bar control and runway-status lights and is tightly integrated with Multicrom CCRs.
