I have been living in an apartment complex for going on 8 yrs.. the some alarms here have been going off day and night and maintenance changes the equipment and batteries, all the time, and within a week or two, they start going off again, to the point that they do not shut off for hours. I believe this building needs rewiring, neighbors in same bldg. have problems but not as bad as mine. I have health issues, and am horribly disturbed by this. Management does nothing but change equipment and batteries over and over. It's a crime!!!
