DMP addressable smokes

I see there are a few DMP fire techs on this forum. I’m hoping for an answer to this question. We are a DMP install/service company and we sometimes run into a issue with backorder parts from our supplier. Is there another addressable smoke detector that is compatible with the DMP fire panels? We currently use only the DMP addressables (2w-blx).

I’m aware there is a liability issue if they are not fully compatible but just curious if there is one that is 100% compatible.



Thanks in advance
