Heat Detector

I am having trouble getting my heat detector to alarm on Konnected using smartthings. I have an Edwards 281B-PL Heat detector connected to zone 1 and I selected smoke detector as the device type in Konnected. It has an end of line resister which I kept installed because when I removed it smartthings would always show smoke. I tried to set the alarm by using a hair dryer to heat it up and to short the contacts but, I could never get it to change from clear. Do I need to select a device other than smoke alarm or is there something else I need to do to get it to work? Here is a picture of what the connections on the detector look like.


I’m having this issue too.
