It looks like your issue is not in fact with the Flame Detector, but with the ‘ALARM:2’ message you’re getting. This alarm most likely means you’re selecting the incorrect 'Start From’ position.

Below are a couple of resources to help you get familiar with the way this setting works. Try using ‘Absolute Coords’ to begin with.
