This sensor is a magnetic contact sensor for doors, windows, and other entry points. When the magnet and the sensor are separated, the sensor sends a wireless signal to trigger the alarm. When you mount one piece on the door or window, and the other piece on the frame, the sensor will activate whenever the door or window is opened. For best performance, you should not mount this sensor directly on a metal surface. The sensor and the magnet should be no further than ¼ inch apart when the door or window is closed. When applying the adhesive tape, make sure that you are mounting on a clean, flat, dry surface.A starter battery is included with the sensor, and we offer additional CR2032 batteries for purchase on our web site.

Tell us what you think about this item. It helps us get better at what we do, and ultimately provide you with better products.
Once you get one that works properly from the start, they are great. I wish quality control was better before shipping. I have put in two systems and both had this unit not working. I think it is the reed that gets stuck.
Easy to install, eficient.
Best DIY security system ever. The products are so reliable and the service is top notch.
I replaced the doorcontact because the battery live is too short, expect this mew model live up as promessed
Small, compact unit. Easy to install on doors and windows. Works with no false alarms since install.






Does this work with my GSM 3G 4G Wireless unit
Hello, this will work with your Vea GSM 3g/4g system. Thank you, Cecilia.
Could you let us know the dimensions of each part of the sensor please? Thanks
Hi, Mickey, The larger half of the sensor (the transmitter) is 7 cm tall by 2 1/2 cm wide, and has a depth of 1 3/10 cm. The smaller half of the sensor (the magnet) is 5 cm tall by 1 cm wide, with a depth of 1 3/10 cm. Thanks, Amanda, Fortress Security Store
i would like to add a door contact to my shed. My only concern is the winter temperatures can drop down into the single digits. Will that affect the contact?
Hi Patrick, As long as the temperature doesn't deep in the negatives then the door contact should still work great in the shed. Thanks, Jessica
