lol, the wholesale sell boxes they have no idea how to fit stuff, your dialer will work with a touch of swearing...
your install is neat, but not how an alarm monkey would do it- bootlace ferrules & a speaker in speaker wire look odd to me
I'm also a semi professional stalker, you decorative work looks good.
I have an acquaintance who's fishes for shell fish & he spends his evenings watching telly, drinking larger & marking lobster pots, to my untrained eye they are really beautifully made & far too good to lob in the sea
