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
  • Tamper switch prevents removing a sensor from its mounting place
  • 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

Total Home Security Door/Window Contact Fortress Security Store Description

The Fortress Total Security Door/Window Sensor is the front line of defense for your home, business or RV. These sensors are designed to detect a door or window being opened. When used with the Total Security systems Ready to Arm feature, these sensors will notify the panel if they are not closed. The panel will then let you know to close the door before arming will be possible. We recommend a Contact sensor for every door and window on the ground level to ensure that any entry is detected as soon as possible.

These sensors do not work with the GSM or S02 panel.

Review by 2241

So far every thing works as promised. Twp door sensors would not work, they were replaced with only one phone call. Manual needs to have more info on the motions, such as what do the dip switches do. Door/window sensor magnet need to be stronger

Arrived on time and as described.
Review by Mike

This alarm system works well. These spares were required because it is easy to break the door contacts when changing the batteries, the tamper contact is very delicate, it could be made stronger.

great product
Review by tennessee kid

As with all of the products I have from Fortress, they work great. I moved my system from Nebraska to Tennessee and will take it with me to next location if we move.

Overall I'm happy with fortress. This order was for a new SIM card to replace one that was no longer working correctly. The new sim was not active when I put it in the system and did take 5 days to activate. It was indicated I may need to restart my system for the card to work. The issue with this is the system is at a remote location and it'll be awhile before I'm able to get there again, so I'm not sure if the system will call me or not at present.

What is the operating temperature range for the door/window magnetic sensor?


Hello Terry, The operating temperature range in the panel can go to 14F to 104F Ni-MH, 14F to 104F for sensors as well. Functions in Relative humidity <= 90% Please let us know if you have any other questions! Thank you, Astrid


Love the sensor but upon changing batteries the "tamper" switch trips the alarm which I understand but is there a way to "quiet" the system when changing batteries?


Hi David, Thanks for your inquiry. To prevent the system from triggering the alarm when changing batteries simply unplug and flip the ON/OFF switch on the panel to OFF. Then replace any batteries and flip the switch back to on/plug the power back in. I hope this helps and please let us know if you have any further questions, thanks!


Will these sensors work with the S6 base system?


Yes, these Total Security contact sensors are compatible with the S6 Titan security system!
