Rated 5 out of 5 by from Well worth the money Well worth the money. Sleek modern design blends well. The blue ring you see in the photos is actually a blue LED light and is normally off so it is all white in the normal situation. Combines smoke and carbon monoxide detection. Actually tells you with a voice message about any issues (smoke, power etc.). If you only burned a toast it would tell you but would not be screaming. If it considers the situation serious enough it will inform you with a voice message and after that will sound a normal loud alarm. Can be silenced from a smartphone when you know about the problem and have it under control. When you are not at home would inform you about smoke via an app. Can gently light your way at night. This is a version for wired installation. There is a battery-only version as well. Installation is easy and you get everything you need including screws and electrical connectors.

Rated 4 out of 5 by from Couple of gotchas... I had the original nest protects installed in my house for nearly 10 yrs, and the first one had started to warn of expiry in March. Purchased two from Screwfix to replace the Gen-1 ones that both expire in 2021. What could have been a 5 minute job became an hour as:- a) connector is different to gen-1. b) hole pattern on backplate is different and smaller. Not a huge deal, but had to fish in ceilings & visit loft for the old wagos and carefully re-drill the backplate holes to cover up the old ones when remounting units. Also remember to delete old ones from app, then go and take the AA batteries out before trying to add new detectors to your set, as the 'location' will be the same and confuse things.

Rated 5 out of 5 by from Great for safety We couldn’t decide if we thought these were just an expensive gadget but they’re great and we feel very protected! They are easy to use and it’s great that they are both smoke and carbon monoxide detectors

Rated 1 out of 5 by from Illegal in Scotland from Feb Just found out these will not be legal in Scotland from 2021 as Nest do not offer a heat only detector for the kitchen and these cannot be linked to one. I have these and will have to throw them away. Do Not Buy. Why are Screwfix selling these?

Would this be suitable for installation outside a bathroom? I want to replace a smoke alarm on my small landing which is the only suitable place upstairs but have found some alarms are constantly set off by steam from the bathroom.

Asked by: RixyQ
Yes. Nest Protect has Steam Check which is a feature that uses a software algorithm to detect steam related events and reduce nuisance alarms that they can cause, while keeping the same level of sensitivity for fire and smoke. Please be advised that Steam Check won't stop all alarms related to steam. If it appears similar to real smoke or fire, even if it's caused by pure steam, the alarm will sound. To know more about Nest Protect and how Steam Check works you can visit this link: https://support.google.com/googlenest/answer/9243882

Can a Nest combined smoke and carbon monoxide detector be position on a wall rather than in a ceiling?

The Heatas engineer for the log burning stove has said the carbon monoxide detectors needs to be 300mm below the ceiling.
Asked by: SASC
This is incorrect, perhaps you picked them up wrong. Any detector should be a minimum of 300mm from where the wall meets the ceiling (and any corner). Fitting outside this area (more than 300mm) on either the wall or the ceiling will work fine although I’d recommend the ceiling if you can.

Can I use this to replace an existing wired smoke alarm which is on its own separate circuit?

Asked by: Windywyn
Definitely! Nest Protect can replace your old smoke alarm system and you can choose between a wired and battery operated version. However, it will not be able to communicate with your older smoke alarm system. Nest Protect only works and communicates with other Nest Protects. If you prefer the wired Nest Protect version, you may still use your old wiring system for your old smoke alarm if it’s using a 120V AC power connector. If you prefer the battery Nest Protect version, there’s no need to use your existing wiring system since the battery version of the Nest Protect will use replaceable batteries that you can remove and replace once drained. You can learn more about the Nest Protect versions here: https://support.google.com/googlenest/answer/9229922

Is this a genuine Nest product because the picture does not show the ‘NEST’ writing on the central circle like the Nest Protect 2 Gen does on all other internet pictures.

Asked by: KentLondonMan
Yes. This is an authentic Nest protect model.
