Has this happened to anyone before 

Never seen that - I think it was possibly lyntec many many years ago had a problem with fires in bell boxes but may be wrong -  (I think that was down to the strobe / capacitor) 

 

I suggest in this instance the bell suffered moisture or water ingress that in turn has shorted the battery out, with no over current protection on the battery it has shorted causing excessive heat / damage 

 

Yeah Lyntec in the nineties had issues, they sent fliers to every household in the UK iirc. 

Not great under the soffit or a thatched house.. 

Is the outside of the cover quite damaged ?

 

I never seen a ni-cad in an EWD overheat

 

However they do blown apart, something about over charging & not being able to vent the gas quick enough ??

So the battery blew up due to Donald Trump capital attack plot?

 

To be honest he was a psychopath anyways

What did you short it with?

Is this EWD a hobby system, or a proper alarm with the EWD outside ?

Pretty rare for NiCD to bust like that without a dead short or overvoltage....
