I used to work for a security co, taking calls and checking up on any alarms that went off during the night. I was able to sleep most of the time as the nise from the system would wake me when an alarm went off.
Until the night I got up half asleep, switched the buzzer off and went back to sleep
In 6 months of being there, it was the only activation that wasn't false alarm. Someone had escaped prison, broke into his gfs parents holiday home and slept there before making off. The oiwners weren't happy with my boss who wasn't very happy with me
