GoRavens,
While 10 seconds would be a good option for some users, the way the system works isn’t as simple as the intruder has 30 seconds to destroy the base station. This has been covered on the forums before and my understanding is that it sends a signal to the monitoring server milliseconds after entry delay starts. You have 30 seconds to cancel the alarm, if the monitoring server doesn’t receive the cancellation signal the dispatch center is alerted. So even if the base station is destroyed, dispatch is still notified.
