I have three linked mains wired smoke alarms in the house I have just

the fault is and how to rectify it?

Might be worth a try - clean the dust and dead flies out of them. If that
doesn't work, you could try disconnecting each one in turn to find which if
any sensor is faulty. I that doesn't work then the problem is probably
central and may be beyond diy.
