Honeywell mk7 keypad hum?

Hi all this keypad constantly hums otherwise all is fine.The keypad appears to work as it should do and I've tested the wiring for shorts,data tampers etc.

Any ideas?

Nor mine.

I've never heard or experienced this or is anything documented with such issue either.

The RKP does not "HUM".
Well, never in my experience.
Have you gone into Option 61 and looked at keypad comms?
Can you describe the noise more if possible.
