How do i stop the constant chirping noise from several fire alarms?

Question

the alarms are about 3 months old, the place is over 30 years old, gross and dusty, its not my apt but the one i'm painting. it started beeping almost a month ago before i started the interior painting. what's going on? the apartments next door and below doesn't have this chirping problem but they have sounded off at an ungodly time on a few occassions but not anymore. just the ones upstairs keep chirping, is there something i can do to help the landlord? ..and that apartment has been vacant for almost two weeks, btw.
