False alarms create two things. When police or the probation officers show up for a false alarm--which could be because of a low battery that the offender forgot to recharge, or something like that--the offender learns that, holy mackerel, an alarm goes off and this happens: they send out people, but they find out there's nothing wrong, so maybe next time they won't send anybody out.
It's the same thing on the probation-parole side. If they have many false alarms, it becomes very confusing for them to know when to treat the alarms seriously. They wonder why they should use up all their time.
