The ELAMT info has now been released. The datasheet is here and the manual is here. It appears that the ELAMT still has 3 separate inputs for the 3 tones (instead of using a special 2-wire protocol), but due to space limitations on the mounting plate, the horn terminals are located directly on the PCB (which appears to be an unmodified AMT). The strobe terminals are still located on the mounting plate.
Also, it seems that the strobe models are only produced in red. The datasheet does not specify which models, if any, have FIRE lettering.
Update August 17, 2025
According to this page, the original AMT is now “to be discontinued.” I have not found a discontinuation notice. For some reason, the AMT strobes also have this designation, despite presumably already having been discontinued, and many other lines on this page are similarly designated.
