[QUOTE="Askie, post: 1123150, member: 25982"] The point in approaching the beam is to try to disable it. If I were to try that, I'd try masking the top pair of detectors (because both an upper and lower sensor would need to be triggered in order for an alarm to go off). If the beam didn't have anti-masking, and I could approach the beam without triggering the alarm, I might just be successful. [/QUOTE]
