Muggling Burglar Alarm

A burglar alarm is a Muggle electronic device used to detect intruders within a premises, such as a home or business. Wizards could easily disable a burglar alarm by a casting a Freezing Charm upon it, as demonstrated by Horace Slughorn, when he disabled the alarm of a house in Budleigh Babberton in the summer of 1996.
