Alarm output

- First alarm:

            + Non-voltage make contact, Contact capacity: 24VDC 1A (resistance load)

            + Yellow LED blinking (slow)

            + Buzzer sound (slow continuant)

- Second alarm:

            + Non-voltage make contact, Contact capacity: 24VDC 1A (resistance load)

            + Red LED blinking (fast)

            + Buzzer sound (fast continuant)

Alarm reset: Contact output and LED display: integrated value is smaller than alarm setting value

                    Buzzer sound (to stop buzzer with a key of front panel)

Operation ambient: 0 ~ 50°C, 90%rh or lower (no condensing)

Remote distance: Up to approx. 500m  (in used of CVVS 1.25mm2 cable)

Case: Steel plate, desk-top type (with rubber foot and tilt-stand)
