Murphy’s got a law.
Whole-house interconnected smoke detectors shall only sound their deafening false alarm in the dead of night.
1. They shall do so several times in the same night, for non-deterministic lengths of time, leaving only enough time between alarms to allow sleep to nearly be achieved.
2. The one of all the sounding units which can silence all alarms must be difficult to determine, and must be located at or above 12 feet of elevation from the floor.
