WDC intelligent alarm door contact

These wireless door/window magnetic sensors are used to protect the opening of both doors and windows. If a burglar opens the protected door or window, a magnetic switch inside the sensor will trip, which sets off the security system. Install one at every entrance to make sure your home is protected. Each sensor is supervised (self-checking) for professional reliability and offers you a choice in design and performance. It will work with a most standard security system which is using the 433MHz receiver.

LED Indicator:
Pull out the antenna of the magnetic detector: When the door or window is opened from the closed position, LED 1 will turn to red for 2 seconds, the magnetic detector will be triggered and will send an alarming signal to the main unit. An indication of low battery: When the voltage of the battery is less than 7.5V, LED 2 will straightly turn on a red light. At this time, you need to replace a new battery immediately.
