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?
