Nest Protect: will soldering in a new carbon monoxide sensor extend its life?

If I solder in a new carbon monoxide sensor, will I be able to extend the life of this another 7 years? Or will the alarm start going off as expired in November

Nest Protect: Why does the smoke alarm go off for no reason.

Sun, 23 Nov 2025 19:23:10 -0700

The smoke alarm goes off for nothing. It's summer here, all the doors are open, not a wisp of smoke around, yet it goes off several times a night. My question is can I take this apart and clean the sensor? The unit is a few years old, and we heat with wood so I'm wondering if there's a buildup on the sensor that can be removed. Thanks in advance.

Nest Protect: Is there an easier way to disable the smoke sensor?

Thu, 26 Aug 2021 10:49:47 -0700

I am looking to install a Nest Protect in my kitchen to use as a Heat/CO sensor and would like to know if there is an easier way to disable its smoke sensor without much hassle?

A new Scottish regulation requires all Smoke detectors and Heat sensors in the house to be interlinked. Given that Nest has no specific product to use as a Heat alarm in the kitchen, I am thinking of installing a Nest protect in the kitchen after disabling its smoke sensor instead of replacing my 4 other Nest Protects with offline ones.

I’d really appreciate any suggestions. Thank you
