Nest Protect - Wired/ Battery options

[jinkster]

Hello all,

Looking at buying the Nest Protect.

We have 2 smoke alarms (not Nest) wired to the mains at the moment and connected together - when one sounds, so does the other.

Wanting to add 2 Nest Protect - wired to replace existing smoke alarm and then add a battery smoke alarm to a new location. Is this possible?

I have one mains powered one, and two battery ones. They all seem to be linked together

Perfect - thank you

Yes, they all work together fine.

Another question - anyone bought one from the USA. Will it work on UK voltage?

Thanks.

I think they're specific for a country's voltage.

(Are they that much cheaper there?).

Haven't checked yet (websites always add tax) but usually in the USA a couple of times per month.

Just to add, I went for the battery powered version and two years on they're all still going strong. I'm surprised and impressed.

I have battery operated ones going a lot longer,

When the batteries do go, use Energizer Lithium. They work much better.

Also, building regs don't allow battery operated in many circumstances - not saying in yours...but regs need to be followed

Both battery and wired versions actually connect wirelessly, not with a link wire, the wired connection is just for power.

I glad I went for wired versions as the pathway illumination is way more useful than I though it would be and a wired connection means it can be set to on all the time when dark if desired.

The motion sensing works quite well for pathway IME. Agree it's useful.

100% this. Don't even try anything else, they will be drained within days/weeks whereas Energizer Lithiums go for over a year easily when pathfinder is used and for ones where it isn't I've not had to replace in >5 years.
