Fire Alarms

[appspark]

Hi again, looking for fire alarms now. only ever done 1 house and it was aico with a 10year lithium backup we fitted. they look quite pricey, see they do a normal alkaline backup version too. do you guys think paying the extra for the lithium is good value? i'm guessing year 10 years the cost of replacing the 9v backups would cost more than the initial outlay for the lithium. Also ive heard fire angel mentioned but never used/seen them myself, if there anything between them or much the same? i like the idea with the aicos if i go for the lithium backup you can get a switch to silence the house/test/identify which alarm went off.
Thanks

I just use the normal alkaline version, never bothered with lithium unless it's only battery operated!

I'm the opposite, only fit lithium now.

I give the clients the choice. It's about 50/50 which ones they pick.

It's only really letting agents I carry it out for and they moan about the prices as it is, just want the cheapest they can get!
