Who not jam the lot?
These things auto-configure insofar that adding a sensor only involves setting a send ID or channel - there is usually no attempt to verify a sensor is still active and connected.
All you need to do is enable a jammer near the alarm box and it won't be able to pick up a sensor signal, staying nice and quiet while you empty the place. You could even go for really pissing off the owner by taking away the sensors too.
Alarms (and cameras) and wireless? Just say no.
