The alarm at my previous employer was like that, it triggered a silent/panic alarm. The idea being that the bloke holding a gun to your head wouldn't blow your brains out until the plod turned up with blues and two's
The only time the alarm activated during the day, due to a fault, it showed up as a panic alarm. I was looking out of the office window wondering why half a dozen coppers were jogging across the road to our office from the station opposite. They were not happy it was a false alarm, I think it interrupted tea break!
