Like the title says, I was curious if these work with honeywell-brand fire alarm panels. They are honeywell-based panels that a lot of people re-brand (ADT for one) and are quite popular in the fire alarm enthusiast area. If I could get one of these modules to work with a panel that would be amazing.
Note I do not own one of these panels right now, I'm debating getting either an MS-25 or MS-9200UDLS. I saw this project and it piqued my curiosity.
