Starting a new thread rather than reviving some of the years-old ones, just started the process of replacing the existing alarm with a Konnected.io one and wondered what people are using to power them? The current alarm has the PSU and SLA charge controller on the alarm board which I want to get rid of, wondering whether I should just get an open-frame/enclosed Meanwell 15V SMPS and a PicoUPS or similar?

Next thing will be figuring out the smoke sensors wire-ORed through a 2.2k resistor...

As a followup, from looking at the PicoUPS docs I can't see any indication of a voltage regulator there. Does this mean that when running off mains power the output is 16V and when running off battery it's 12V? The Konnected.io board has a DC/DC converter on it so will run from 6-24V but I just want to check that that's not going to cause problems.

Maybe just use a 12v led down light driver. https://www.lightingplus.co.nz/lighting/exterior-lights/garden-lights/dracv-12-v-1-20-w-constant-voltage-led-driver? konnected doesn’t use eol of resistors. If the smoke alarms require 12v you could use the the led downlight driver to power these as well.

I have the konnected pro powered via Poe currently. I have the aforementioned power supply type available but have not hooked it up.

The power supply isn't the problem, I've got decent-quality Meanwell ones if I just need 12V, however that doesn't solve the SLA battery backup problem and I'm not sure I want to spend a pile of money on something like a Constant Vigil and then have to wire up a pile of barrel jack cables to connect to it.
