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 choice in design and performance. It will work with most standard security system which is using 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 alarming signal to the main unit. Indication of low battery: When the voltage of battery is less than 7.5V, LED 2 will straightly turn on red light. At this time, you need to replace a new battery immediately. Specification: Power Requirements: DC=12V-8.4V (23A DC=12V Battery Included) Current Consumption: less than 20uA; less than 15mA while transmitting Transmit Frequency: 433MHz Transmit Duration: less than 1s Transmit Distance from host: more than 80m (no obstacle) Installation: less than 15mm between part A and part B Coding Type: Fixed Code Dimension (LWH): 71x36x15mm Operating Temp: -10 ~ +40 centi degree Humidity: less than 90% Shell Color: White Package Included: 1x Magnet Sensor 1x Battery 1x Double-sided Stickers

No es practico
1) El producto llego con la batería muerta.2) No es practico para instalar ya que no cabe en una ventana o puerta.3) Esto es para algo con mucho espacio.

Good door/window sensor, specific for 433mHz units
Needed this to help catch mailbox thieves in our neighborhood. After mounting correctly, this sends a signal every time the mailbox is opened, that is picked up by a separate alarm base which then sends me a text message. Now I know when the mail is delivered, and also if someone prowls the box at night. Alarm bases work on either 433 or 315 mHz sensors. Make sure you have the correct frequency sensor for your system.

Weaker magnet than GSM panel sensors.
Magnets won't work with earlier received GSM Panel magnets. Don't mix them up and test before mounting...
