First Alert Smoke C/O Detector (ZCOMBO)

So, I recently had to hard rest my hub due to a firmware update changing the zigbee channel and something causing interference.

i was able to add back in all of my previous first alert smoke c/o detectors (zcombo) with little to no trouble after first excluding them.

the new first alert smoke c/o detectors are being a royal PITA to get paired. These are the ones in the new smaller package. While the package says ZCOMBO on the back above the UPC, on the front top right it says ‘works with ring’.

i’ve been able to get 2 to finally pair after major trouble, excluding several times in a row, then trying to pair several times. though when they do pair they are pairing as ‘z-wave basic smoke alarm’. then, i go into the IDE and change the device handler type to ‘z-wave smoke alarm’. on the app it shows clear and clear for both smoke and C/O.

is anyone else having a royal PITA time trying to get these new first alert smoke c/o detectors (zcombo) paired?!

It appears to be the same model, just new packaging.

Yup, still ZCOMBO model, but something must have changed somewhere as it takes a moving of the earth to get these new units paired. The older units that I already had paired almost right away. when they paired (older units) the listed name was ‘First Alert Soke and Carbon Monoxide Detector’ vs. when the new units paired finally the listed name was just ‘Z-wave Basic Smoke Alarm’.

This thread is a few months old now, but I’m posting here as it seems relevant.

It looks like this may indeed be a new model of the First Alert ZCOMBO. The new one is labeled ZCOMBO-G. There is a new Z wave certification, and the Ring product page for this lists it as “2nd gen”. As best I can tell, the only difference appears to be a newer z wave chipset since it is now listed as supporting S2 security. The S2 piece could be why the OP was having trouble pairing these.

The only odd bit is how the OP got this in May when it looks like it wasn’t certified until June! :wink: This would likely also explain why I had trouble finding one of these (the first gen) in stock when I had to replace one a couple months ago.

The certification:

First Alert’s product page:

And finally Ring’s page talking about their integration:

I bought another ZCOMBO today at LOWES since there may be an issue with the ZCOMBO-G model.
I had no problem setting it up with my ST Hub.

I’m a novvice with Smart Thongs. I have a Samsumsung hub with sensors, plugs and cameras connected. However just purchased a First Alert ZCOMBO and I notice it is the new -G. Will this pair to my Samsung hub?

I only have the older model, so I can’t say for certain. However, this appears to be an extremely similar model that has been updated to include S2 security so I see no reason it wouldn’t work.

For S2 to work properly, you’ll want to avoid the “scan nearby” feature when adding it in and instead find the device by drilling into the list of brands to initiate the pairing.
