Why does the fire alarm beep for no reason? There are no fire hazards.

Some smoke alarms beep if the batteries are dead or perhaps not put in correctly. Hard wired ones will have back up batteries that need to be replaced occasionally and they may beep if the are not wired properly.
There are some alarms also detect carbon monoxide. You may have a separate problem to investigate if it is a dual purpose alarm.
If it truly is broken, they are not that expensive to replace. It is very important to have a functioning smoke alarm.
It's usually caused by a low battery. Change it to see if that is the problem.
