    3. Alarm



    ItemYes/NoTechnical indexNote
    Power failure alarm signal

    Yes


    Input: normal, output: low impedance;

    Input: failure, output: high impedance;


    		When DC input fails, alarm signal of +28V output at full load rise to +2.2V, (need to add pull-up resistor when test). Time interval for +28 V falling to +15V shall not be less than 1 ms.
    Input normal LED display

    Yes

    		Use indicator light (red): red light turn on means input is normal
    Output normal LED display

    Yes

    		Use indicator light (green): green light turn on means output 28V is normal
