App and panel show different sensor states

Support
1

I have a DSC1832 with a RFK5500 panel. At the panel, all sensors show as closed and I can arm/disarm.

On the Surety Alarm.com app, the gate sensor shows as open and I cannot arm the alarm via the app.

The battery is new. When I remove the sensor cover RE322, it correctly alerts the tamper in the app. I have removed all the wiring to the exterior gate from the sensor and have a loop between the contacts to eliminate wiring as the culprit.

Everything works perfectly inside the house, but I cannot get the app to recognize that the sensor is properly closed.

Any ideas?

What is the name of this sensor as it is shown in Alarm.com?

I am not seeing any sensors reporting open at this time. I do see a sensor labeled Patio Gate which is showing closed status.

When using the sensor as a transmitter for an external contact, make sure there are no resistors in use.

Do you still have a jumper between the terminals? Would you mind posting a photo of the sensor?
