Here are all the commands for communicating / controlling the FCI E3 and S3 fire alarm control panels.
Note: When sending the commands make sure you’re using plain text and set your terminal app to ONLY APPEND A SINGLE CR CHARACTER. The carriage return part is important. Also, sometimes you’ll get a weird response from the first command, just try it again after a few seconds and the panel should respond normally.
