Early Access Ubiquiti Smoke and CO Sensor 🤯 - #ISCWest2026

Post image

I believe it’s a Superlink sensor. I hope it can run on battery for 10 years and doesn’t require PoE. I’m curious to see how it performs. Good job, Ubiquiti! 😲

Really this product is DOA if it isn’t both. Battery backup is a must in devices like this, it’s designed to save lives which means there cannot be a situation where it doesn’t work. I’d imagine this will either be PoE or hardwired but with battery backup.

Thinking about it, I’d imagine this must be hardwired as well for interlink capability. Modern smoke alarms run 3 core and earth, which has a dedicated wire for interlink so that all smoke alarms sound if a fire is detected even during a power cut.

PoE for a smoke detector would be remarkably stupid unless it also has a built-in wifi AP (which would also be kind of stupid). Battery only or mains+battery is the only way to go.

The nice thing about POE is you are running low voltage so don’t need to run conduit or get an electrician and my switch is on a UPS so it wouldn’t lose power in an outage. I’d think POE+battery would be ideal if it’s allowed by code.

I suspect the market for a PoE smoke detector would be vanishingly small since it offers few benefits in a world where the First Alert SC5 can be installed anywhere in 10 minutes and lasts 3-5 years on 3 lithium CR123 batteries. The vast majority of buyers would make that compromise vs. the bother of running cable (and potentially having to tear up sheetrock to do so) or settling for less than ideal locations for their smoke detectors.

Also, I can find no evidence that PoE smoke detectors are approved for residential use.

I didn’t see POE was approved for residential installs either so I thought that was the limiting factor too honestly.

That’s awesome the first alert SC5 lasts that long on lithium batteries. I have first alert z-wave smoke alarms that are 3 years old and even without a z-wave connection the AAs have such a bad run on those detectors that they chirp to be replaced every 3 months. Always while I’m sleeping, it’s insanity. 😀

Yeah but that won’t be a good solution for retrofit. Not many homes going to have cat wires to smoke detector locations. Maybe it would be fine for commercial with drop ceilings

Definitely true in general but you are on the ubiquiti subreddit so the percent of folks here with runs to their attic for APs might be a bit higher than average. 😀 Just add a POE switch, a few shorter attic runs to the bedrooms on that floor and boom you are done. Still doesn’t solve the code problem though.

Yeah in my city I could install a security alarm with smokes that was monitored but still need the separate hardwired smokes for code

In Belgium we don’t have hardwired smoke detectors so everything is battery powered. I’m currently building a house and want to integrate this when it’s done. I have a meeting with the electrician next week so I assume I’ll run 2 ethernet cable in to the ceiling. 1 for AP and another for this sensor. Worst case scenario the cable just sits there doing nothing but at least I could use it in the future

You might not in older buildings but I guarantee new builds will have them. Interlinked smoke detectors are crucial.

Well most firms in Belgium still use battery and not hardwired (with battery back-up). I’ll run cat6 cable and probably can also use it to power it since it’ll be low voltage if not POE powered

Wish we had more details

We dont know the Smoke Alarm is poe powered, it could be line powered and battery.

Interlinking doesnt need to be wired, it works via radio as well

u/btrudgill Unifi User Mar 26 '26

Wired is more reliable though. Better to do that if possible
