Alarm Detector / Photoelectric Detectors
  • Applications       

    The IRB-250 quad photoelectric detectors one designed to trigger an alarm relay upon the detection of intruder through 4 active infrared beams.


    100 Time Sensitivity Allowance

    Stable operation even 99% the beam energy weaker is blocked by rain,fog,frost,etc.

    Quad Beam Detection

    All four beam need to be blocked simultaneously to trigger an alarm. Lessfalse alarm caused by birds and other small animals.

    Lower Beam Module Blocking Detector(LBMBD)

    When LBMBD is blocked for 4 seconds; alarm relay will be activated (then function is selected)

    Alone Adjustable Mode

    LED signal strength indicator+the alignment status indication buzzer. Beam is Alignment much easier by sound and light indicator.

    Beam Power Control

    This option allows selection of the appropriate beam in-tensity relative to the detection range to minimize the risk of reflection on the nearby walls and cross-taking with other detectors.

    Beam Interruption Time Control

    This feature can be used to adjust the beam interruption time to best fit the application.
