Lc1-mfd metal fire proof cover, with innovative ceramic

 connector, lc1-pib pilot sound indicator board speaker can be installed with optional pilot sound indicator board. This small PCB with LED indicator can be fixed in the holder and then connected to the standard light guide. After that, the user can visually check whether there is pilot tone by flashing the LED indicator integrated into the edge of the front cover. The required pilot tone signal level is 4 V RMS (20 kHz), so the load of these indicator boards on the power amplifier can be ignored.
