Each dry contact output is associated with a sensor and the blue LED above each output reflects the sensor connectivity:
LED off: the output is unaffected,
LED flashes: the sensor is not present in the network (not yet connected, temporarily [...]
During the initial calibration, the system records the value of the magnetic measurement corresponding to a free space. In order to be robust to changes in current magnetic field conditions, the sensors incorporate a self-calibration algorithm.
Once installed on site, each sensor must be calibrated in a free space to reflect the magnetic field corresponding to the non-occupancy of the space. Two options are available:
The 3 point blue connector with jumper, supplied with the HIKOB [...]
