If looking for more than 1, they are on sale at Costco too. 3 for $80.

Yea. This is disappointing. What happened to Nest. Google ruined it. They were once cutting edge. Where's the Gen 3 wired nest protect that adds some unique high end features.

I bought one last year, but for some reason, batteries do not last more than two months, I've tried many battery brands.

Buy from Costco [costco.com] to screw Amazon. Same price now.
Unlike Amazon, Costco treats their employees like humans.

Edit: I am sure if your warehouse has these, the price will be even better.

Need some input. I have the Kiddie ones in most rooms but did a remodel, contractor ended up closing some of the hard wired locations by mistake.

I know if I get this they won't pair or interconnect with Kiddie but does anyone know if the wired version for example Kiddie would connect with their wireless version?

Or is it best to just get these around the gas stove being installed on battery and leaving Kiddie hardwired interconnected.

What is the benefit of Z-wave on the smoke detector? Is it just being notified if you are away from home and it goes off? Do people hook it up to a secondary horn, flash the lights, or some other integration?
Saving your house from totally burning down even if you're not home. Also gets better insurance discounts. On the regular, I got tired of my hardwired shit always going off (one would malfunction or backup battery low and set the whole house off) and not knowing which one it was, the Z-wave bits let you name where you put them and you know exactly which one is low.

See my last reply here. I went from Kiddie hardwired to this. I even bought brand new Kiddie before doing this, they were all problematic and frustrating waking up at night thinking there's fire but it's just something wrong in the chain somewhere.

What did you do with the kiddie hardwire plates? Did you just patch up the ceilings and put this on top? I assume the brackets are not compatible.

Overall are you satisfied with the switch? Is the sound loud enough?

Quote from snovvman :
I thought CO detectors should be placed low, as it is heavier than air, while smoke detectors up high, as smoke rises? While I like the idea of a combined sensor, it would seem to not provide the best CO detection if placed on the ceiling.
This is incorrect. Carbon DIOXIDE is heavier than air, but carbon MONOXIDE is not. It's slightly lighter than air, but so slightly that it's ok to have them lower than the ceiling because it mixes evenly around a room (unlike smoke detectors which MUST be high up)

I replaced them with the first alert brackets and just touched up the paint, they were bug enough to cover the single gang hole.

Happy with switching, the only downside here is the battery life (still yearly, or more) due to the ZWave
