When the fire warning control box fails, (located in the dry bay) it often give false indications of a fire.

Your HF problem is most likely a problem with the screen/shielding between the HF Coupler unit and the HF antenna mast. When you transmit on HF the Radio Frequency (RF) energy is leaking inside the aircraft and inducing currents in the warning systems you mentioned.

We never had that many failures of the FCU. It seemed to be pretty reliable. Considering it is located in the drybay, it held up very well. It is a sealed unit, so I suppose vibration and temperature changes just wear out the internal components.
