How to use
Mount the magnetic sensor components on the rack door and the corresponding magnet or contact on the door frame at aligned positions so the sensor detects closed and open states reliably. Route the 12 ft cables to the monitoring appliance or sensor input on the NetBotz device, securing the cables with the supplied cable ties to prevent strain. Configure the monitoring system to recognize the door-switch input and set thresholds, logging and alerting rules according to your operational policies.
Usage recommendations
Install sensors inside the enclosure away from moving components, ensure magnet alignment for consistent detection, and avoid tight cable bends. Test each sensor after installation to confirm correct reporting in the monitoring system and use the cable ties to maintain secure, organized cable runs.
