The RE104 registers large objects disturbing a magnetic field. There is also a sensitivity adjustment using the jumper on the board. See the attached image.
Have you tried setting it for high sensitivity?
Also, I do not know that using the “Door Bell” sensor type will produce the proper serial number on the Qolsys panel. The second to last character for the sensor ID will populate based on the type of sensor you select. It needs to match the serial number on the RE104. For the Sensor Group you can still select Local Safety Sensor Group 25 for a number of different types (doors, motions, etc.) and this is the Chime only no alarm signal sensor group you want.
What is the serial ID on the RE104 sticker?
