      If your Detex Security System is not powering up, check the following: 1. Ensure the battery is correctly installed by removing it and firmly reinstalling it. 2. If the cylinder microswitch lever is broken, the microswitch needs replacement. Remove the PCB and return it to Detex for repair. 3. Verify the cylinder installation.

    • V

      If the external magnet is not working on your Detex Security System: 1. Ensure the device is set for an external magnet by sliding MagRst to ON then OFF, and listen for three chirps. Then, disconnect the battery, turn JP1 to the OFF position, and reinstall the battery. 2. If using MS-2049, ensure it is wired correctly by connecting the MS-2049 black and white wires to the green connector.

    Why is my Detex Security System not arming when Auto Rearm is OFF?
    • A
      Ashley SchwartzAug 28, 2025
      If your Detex Security System is not arming and Auto Rearm is OFF, it could be due to: 1. The magnet not being aligned correctly. Use a magnet locator to install the magnet, referring to the magnet handing instructions. 2. A dead battery. Replace the battery.
