Door Sense LED Blinks 4 times/second – Circuit NOT calibrated

What does Door Sense LED Blinks 4 times/second mean?

This very rapid blinking pattern (4 Hz) signifies that the associated door circuit has not been calibrated. The circuit is therefore not in a functional state and requires setup.

• The door sense circuit has not been calibrated.
• Incorrect or missing resistor values at the door contacts.
• Initial setup process was not completed for the circuit.

Click steps to track your progress.

1. 1

   Perform the proper point-by-point calibration procedure as described in Section 2.2.5.1.2 of the LiNC-NET Administrator Guide.

2. 2

   Ensure resistors are correctly installed at the door contacts and all switches are in place.

3. 3

   Verify the door is in its closed (normal) state before initiating the calibration procedure.
