To ensure uninterrupted operation of the public address and voice evacuation system during a fault condition, this loudspeaker is equipped with integrated short-circuit protection:
A Ceramic Terminal Block ensures high-temperature resistance and electrical isolation of the input connection.
A Thermal Fuse automatically disconnects the loudspeaker driver in the event of excessive heat (e.g., due to fire or driver failure), preventing a short circuit across the 100V line.
Do not bypass or remove the thermal fuse under any circumstances.

Ensure correct polarity when connecting to the ceramic terminal block. Verify the integrity of protection components during periodic maintenance.
