alarm systems do detect open wires. E.g. windows with an aluminium/metal strip on glas do break and interrupt the quitsense current which will in case of an intruder activate the alarm.

Just a different style with a latch system to keep alarm on once activated. http://everycircuit.com/circuit/4757550800306176
