What IS the point of an alarm that keeps going for… checks clock … 17 keffing minutes!!
If no-one has turned it off by now, then either the burglars have buggered off, or they’re still in there knowing fine well that no-one is investigating the alarm.
OK, if I’m honest I’m hoping that writing and posting this will cause one of those coincidences where, the second I hit the PUBLISH button, the alarm ceases.
