Not 100% sure if they make a LV combo, I use a relay in 120v smokes

I am a EC not a LV contractor and used this set up many ,many times, and love it ! relay for the co , relay for the smokes, on different zones, Any time this issue comes up all the LV contractor flip out. Hower, I would like to go all LV in this case, any suggestions out there?

Is that a relay that is listed for this application? I think it would need to be listed for the application in the event that it fails to do it's job. I think there would be some liability involved with using a non listed relay to report to a panel.

You do not need a dual technology smoke detector if it is a low voltage fire system. 527 CMR 32.02 (3)
I believe what I read was it can be photo electric hardwired or wireless. It is not required to be ionization type. I guess they don't make them any more for residential systems?

Check the power point out. Obviously check with the local officials to see if that is how they interpret it. You never know in Mass.:roll:
