Looks like a good deal. Not z-wave though.

I wish these were hard wired.
I bought these.

I have several of the older units (Zwave) that do not communicate with each other, but otherwise seem to work well. Hoping they do as advertised - when one alarms (audible) they all alarm.

I also set up SmartThings to turn on all lights when a unit goes off. I know this works because my smoke alarm is often my wife's kitchen timer for cooking.
FYI there is a new UL standard for smoke alarms going into effect later this year. I am waiting for the new alarms to be sold before I replace mine.

it doesn't says specifically, but based on a few reviews, these are AA battery powered and not 10 year internal battery like is required in many places now.

Bought the z-wave pack from costco and didn't realize these things are AA battery powered, which I then found out is against code in California (and in many places). So they're getting returned. Seems like the type of thing they need to be very explicit about when purchasing.

I've got these in my house. It does suck they are against code in many places by not being hardwired, but I'd rather have one of these than a hardwired unit that doesn't work with my security system. I kept all my old detectors so I can revert if I ever sell the house.

How does a combined system compare to just a smoke alarm? Specifically, I was looking at these at Amazon which are the same brand, smoke alarm only, but more expensive:

I don't have a hardwired system, I already have a CO alarm on each floor that I bought last year. I like the idea of getting some interconnection between my floors. Is having 6 CO/smoke alarms overkill?

A lot of regions have a specific rule allowing "interconnected wireless" smoke detectors for security systems. Many security systems use zwave smoke alarms so they qualify. Since they are monitored and can throw an alert when they are offline, the shorter battery life is acceptable, especially since it can also trigger a remote fire alarm, cause lights to turn on, etc.

As said, z-wave alarm is considered as interconnected, when properly configured with a hub, so it is compliant to the "interconnected" rule.
And the non-z-wave alarm in this deal can also be interconnected.

Also, in CA, hardwired with battery backup is only required for new construction or new renovation that requires permit
So, both these batter powered z-wave or non z-wave are perfectly legal to be used in old houses.

Z-wave can be interconnected?? Can you provide more details on what are proper configs and hubs to be use so they can be interconnected?

Any of the popular z-wave hubs should work, SmartThings, Vera, etc. Basically it'll tell you if any 1 of the alarms go off.

I have this pack, and it augments my hardwired units and doesn't replace them. I like having something that'll notify me if I'm not home.

Zwave is an automation platform that has a number of devices that are UL rated for use as security systems or, like this, fire alarms. They provide info on battery status as well as separate alarm states for smoke, CO, etc.

Any controller beyond A simple remotes will qualify. I use HomeSeer, which can also integrate with several security systems. Hubitat isn't a bad one, though with only one model, if you outgrow it you are stuck.

I have my homeseer turn on all the lights during a smoke alarm event and send me text messages and emails.

The ability to trigger the siren is up to each smoke detector manufacturer. Of course there are also zwave sirens/sounders/ an ouncers you can buy separately. I have two such devices that also play chimes for the doors opening, pre-recorded MP3s with tornado/flood warnings, and messages about the laundry. (I tend to forget about the wet clothes)

Agree to the z-wave automation platform, but my original question was on the comment regarding interconnected first alert zwave alarms. I have't seen if first alert zwave can be interconnected. It can alert you via app (ring, smartthings etc) but if one go off, it will not trigger other alarms to go off (not interconnected).
