Installing battery smoke alarm

wanderer 22

Hi all,

Apologies in advance for my lack of electrical knowledge...

I'm looking to replace my existing hardwired/mains powered smoke with a Google nest protect battery model. Can I simply install the nest where the existing alarm is and if so do I need to remove the existing wires that attach to the current alarm?

Thanks in advance!

I wouldn't replace mains+ battery for battery only

I would get a rec to upgrade them if necessary to the latest EI dual alarms EI3024 and a EI3014 heat alarm

Your money would be better spent

Nest protect comes in battery and battery or wired version. It is a carbon monoxide alarm, heat detector and smoke alarm. I have a few battery ones. Batteries last years and the device itself should be replaced after 10 years. Wired is probably a better option

Agreed.

The nest battery alarms would be a decent upgrade to the old 9v alarms.

You'd have Optical +CO and wireless interconnect , long battery life

Mains wiring I'd favour the EI Alarms

Reason being you'd have the wired interconnect anyway most likely with the mains wiring

Nest is saying only 15m interconnect range (excluding) obstacles and needs setting up.

I would say the newer EI 3024 wired interconnect would be a better alarm setup and leave the CO separate

Better fire response I would say with the EI optical/heat

Nest has the advantage of text alert included

I'm not seeing any nest smoke heat co alarms on a search ?

Only smoke and co ?
