product_description: <b>NO AND NC:</b><br> NO means Normally Open: when the magnet separate, the circuit is conductive;When the magnet together, the circuit is not conductive, NC means Normally Closed:When the magnet together, the circuit is conductive; when the magnet separate, the circuit is not conductive.<br><p><p><b></p></p><br>Wired magnetic door/windows contact can be added to wireless/wired Alarm Systems.(some wireless system has wired zones).They are best for protecting doors, windows and any other other you want to protect.</br><p><p><b>Technical Parameters:</b><br>Economic solution for Non-metal door/window protection;<br>No external power supply, connect to wired or wireless alarm control panel GND and NO ports directly!<br>ABS material;<br>Alarm distance: 15mm-30mm
product_bullet_point: 【Reed Switch】 ：IMPORTANT : When the magnet is near it makes connectivity, when the magnet is removed connectivity is broken.Wired magnetic door/windows contact can be added to wireless/wired Alarm Systems.(some wireless system has wired zones)
  【No External Power Needed】 ：Connect to wired alarm control panel, GND (Positive) Connect with NC(Negative) ports directly which make signal stability and no trouble for the battery. These Wired Reed Switches means it needs wire to connect with the alarm control panel, but wire is not including in the package.
  【Install Distance】 ：Gap between 2 pieces more than 15mm, less than 25mm.White color make home great and beautiful. Anti-fire ABS material.
  【Install Attention】：Item CAN NOT connect directly to power, it works with your alarm system provide a switch signal.Working current under 12V.
  【What NO NC Means】:NO means Normally Open: when the magnet separate, the circuit is conductive;When the magnet together, the circuit is not conductive. NC means Normally Closed:When the magnet together, the circuit is conductive; when the magnet separate, the circuit is not conductive.
