Try setting alarm and pressing reset again
Cover has a spring behind it which might not be making contact
If engineer reset , then there is a special code and you will have to call out a local engineer to do it for you perhaps
If it's a locked version not sure if any were but then may mean replacing whole panel
Panel just wire the two cores to a zone and that's it , the panel uses two cores for the zone for tamper and alarm , which is why eol is done at the sensor
On a Sunday morning ? Probably staring at the ceiling from bed not always looking at phone?
Or he's in church staring at ceiling praying you stop doing his head in?
Deterrent?
Professional dummy box like a ADT box off eBay probably be better than what your trying to do, no offence intended
Forget the dog buy the box and then play around with the alarm for the next 6months while ADT box is up there , get flasher unit with it if you can
Locking panels that can be easily unlocked always strange
Even these lot , not even worth the money they doing it for
Might as well do it with the enforcer etc aswell
You must get real bored , or looking for ion gear lol
That mic was another classic, they used the same body for keypads and all sorts of someone wanted something odd made
