Esser LSC-606/DC 6 W 6.5 Inch EN 54 Ceiling Speaker, Capacitor-Coupled Line Supervision

This model is manufactured for systems where the speaker line is supervised with direct current. It has the same 6.5-inch driver as the LSC-606; additionally, its internal capacitor isolates the speaker from the DC supervision signal, enabling reliable detection of line breaks. It is mounted flush in suspended ceilings, protected by metal fire-rated enclosure and ceramic terminals. It eliminates the risk of undetected cable faults leaving zones silent.
