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 23A batteries for purchase on our web site.

  • One “23A” 12-Volt battery
  • 433MHz wireless signal
  • ~ 150 ft. range, with line of sight
  • LED light flashes for 1-2 seconds to indicate activity
  • LED lights up solid to indicate a low battery
  • Magnetic sensor protects doors, windows, and other entry points
  • Ready To Arm - system knows if a door or window is left open
  • Mount on a clean, flat, dry surface. Place a spacer between the sensor and any metal surfaces.
  • LED light shows activity and low battery warning

I have been using an existing Fortress security system for about 3 years at my business. When the new systems became available we were wanting to upgrade to the added benefits of the new systems. Wanting to get the best value for our investment. We waited for the Black Friday sales event to buy 2 systems thinking that this would be the best time to purchase. So the orders were placed at a 20% discount. and wait for the product to arrive. All good right? It was, till they e-mail a 25% off promotion for cyber Monday, before my order even arrives. Go figure!

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
