ZCOMBO First Alert link or interconnect devices

These devices don’t natively link or interconnect with themselves according to First Link’s documentation. However, does anyone know of an app that exists to do something like that? If not, shouldn’t it be possible for all others to sound once one is triggered?

These devices are designed to use as little battery power as possible and thus they don’t receive alarm commands. The best you can do is catch the event and turn on another device such as siren or Sonos speaker.

I had the same idea as you. However, I find the alternative better. If all the alarms went off, you can’t figure out which one triggered it as easily. Now I have an Aotec alarm with a different sound and Sonos announce which alarm went off as well as the triggered fire alarm. In a fire, every second could make a difference.
