Wired smoke alarms

[annelid]

We have wired interconnected smoke alarms in our terraced house. They need replacing

They are not mains wired, just wired together so if one goes off they all go off. They have a battery as well.

I cannot seem to find any replacements. Just mains wired or wireless.

Can anybody recommend any?

Thankyou

Aico are decent, though not the cheapest

We have Ei100c, they are discontinued, as is the next generation of them. I think they are Aico now

Yes all 3. Aico is the ones I've looked at but they don't seem to be able to be battery powered interconnected

I'm not sure they do battery powered with wired interconnect, but they do mains powered with wired interconnect and battery powered with wireless interconnect
