    How to troubleshoot Optex AX-330PLUS with no action after applying power?
    • T
      Thomas ElliottAug 5, 2025
      If there is no action on the transmitter or receiver of your Optex Security Sensors after power has been applied, you can try the following: * Check that the power wires are properly connected and the polarity is correct. * Disconnect the power wires from the power supply and check the photoelectric beam and test for a short or open circuit. Also test for a short circuit to ground. * Consider that the power wires may be too long for the gauge being used. Use heavier wire or add power supplies closer to the farthest unit. * Measure the voltage to ensure the power supply does not output more than 12 VDC. If it does, repair is required, or call the power supply manufacturer.

    What to do if Optex Security Sensors have false activations?
    • R
      regina05Aug 12, 2025
      If your Optex Security Sensors are experiencing false activations, consider the following: * Use the HU-2 heater unit. * Turn the beam’s interruption time adjustment clockwise one graduation. * Cut off branches or new grass, and secure debris to avoid unnecessary activation. * Re-align the beams. * Adjust the interruption time, change the mounting height, or move the beams to avoid perching birds or small animals crossing the beam’s path. * Move the beams to avoid the rising or setting sun, or swap the transmitter and receiver locations. * Remove any object causing reflection, or move the beams. * Check for shorts, opens, grounds, and high resistance on the alarm circuit wires. * Clean covers both inside and outside using a dry soft cloth or mild soap and water only.

    What to do if Optex AX-330PLUS Security Sensors alarm zone has no action when beams are blocked?
    • N
      nancyhodgeAug 20, 2025
      If your Optex Security Sensors alarm zone has no action even though the beams are completely blocked, consider the following: * The control panel may be malfunctioning, in this case call the control panel manufacturer. * Re-wiring of the alarm circuit wire may be required. * Re-program the zone’s "loop response time" appropriately. * Remove power from all transmitters and conduct a walk test. * Change the layout of the beam, or call a technical support for further advice. * The receiver may be affected by electrical noise. May need to use shielded wires and/or metallic conduit pipe. * Turn the interruption time adjustment dial counter-clockwise one graduation. * Adjust the mounting height.

    Why Optex Security Sensors generate alarm signal if beams are not blocked?
    • D
      Dwayne ColeAug 27, 2025
      If your Optex Security Sensors are generating an alarm signal even though the beams are not blocked, try the following: * Check that the "monitor jack output" value shows 3.0 VDC or above. * Check the alarm circuit wires for shorts, opens, or grounds. * Re-align the beams using a voltmeter to ensure proper monitor jack output voltage. * Remove any objects or move the beams.
