Smoke alarm help needed

[BB22]

Hi everybody, I have 3 hard wired smoke alarm, no batteries, one on each floor all connected together, I believe the term is chainlinked, and for some reason they are ringing not stop. Don't know the one that's causing all of them to rign. Their is no smoke so I don't understand why it's ringing. Can anybody help please.

I would just replace them all, especially if they are more than a few years old.  They are cheap enough.  And hopefully you DO have batteries in them. Even hardwired smoke alarms have a battery backup.

No batteries they are connect on the 120v

No batteries they are connect on the 120v

that gives you another reason to replace them since that feature has long been required by code.

Replace them with new units. Preferably with batteries.

The main reasons why smoke alarms ring when no smoke is present are:

•  Cover or Sensor Chamber is Covered by Dust or Dirt.[SIZE=14.6667px] [/SIZE]
