Honeywell G2-20 F2 fuse blowing

[Hitz]

Hi

I have had a Honeywell G2-20 alarm installed for over 5 years and it has worked without any issues.

During the hot weather, I did have one of the sensors send an incorrect intruder alarm trigger which I just took as a one off event.

Another wired sensor in a different zone then started omitting a tamper fault so I temp set that to a spare zone to enable me to set the alarm.

However, recently the keypads display went blank and I realised the F2 (Aux) fuse had blown so I replaced it.

Then a day later the F2 fuse blew again.

The alarm has had a surge protector kit which was installed the same time as the alarm.

Any ideas what could be causing this?

Thanks

If the fuse F2 only supplies the keypad then that would suggest it is faulty.
Don't know anything about your other events

Something is chewing the cables ? Mice / squirrels…. Would be my guess
