A firm alarm is never a welcome interruption (except I suppose when there really is a fire). A fire alarm is especially offensive in the middle of the night when one is sleeping. This morning for example we were unexpectedly awakened at 4:45 AM by a fire alarm. Earlier in the evening while dining at table we had endured a similar impetuous fire alarm. There was fortunately no readily apparent reason for the fire alarm on either occasion, either inside or outside the apartment in the hallway. We have three fire detectors each of which has its own voice warning of “FIre Alarm” in addition to a screeching sound. When one device gets going, the others follow suit similarly (though thankfully not in unison). I suspect the customary early morning tranquillity enhanced today’s irritation.
