Most false alarms in a building come from the same two or three detectors.
Usually it's the wrong device in the wrong place. An optical smoke detector can't tell steam from smoke, so put one near a dishwasher, a shower room or a toaster and it'll keep going off. Same story with dust in a workshop.
The answer is normally a heat detector or a multi-sensor in that spot, and sometimes just moving the head a couple of metres away from a doorway.
Before changing anything, keep a note of each activation. Device number, time, and what was going on in the building at the time. The pattern usually shows itself within a few weeks.
It's worth sorting out. People who have evacuated four times for nothing won't move as quickly on the fifth.
