10PCS Wired Door Sensor,NC Recessed Wired Door Window Sensor Magnetic Reed Switch for Home Security Alarm System

Produktbeschreibung

Normal Magnet Proximity Behavior​:Magnets in the sensor are usually close to each other, which is a normal state. This inherent arrangement forms the basis of the sensor’s operation, ensuring wired window door sensor functions as designed when in the default position without external interference Magnet-Switch Interaction for Circuit Control​:Wired door sensor close magnets create a short circuit, forming a current path, with the switch off in this state. When magnets and the switch separate, the switch opens. This interaction between magnets and switch controls the circuit state, enabling detection of door/window movement No External Power Supply Needed​:The sensor operates without requiring an external power supply. This NC recessed wired feature simplifies installation by eliminating the need for additional power sources, making it easy to integrate into home alarm systems without complex wiring for power Direct Connection to Alarm Panels​:Door window sensor magnetic reed switch directly connects to GND and NC ports of wired or wireless alarm control panels. This straightforward connection method ensures compatibility with common alarm systems, facilitating quick setup in home security configurations Not Suitable for Iron Doors​:The sensor is not suitable for iron doors, as iron can reduce the magnetism of the sensor. The NC recessed wired door window sensor magnetic switch limitation arises from iron’s impact on magnet performance, ensuring users avoid installation on such doors for reliable operation
