OMD- 24 Series

The OMD-24 Bilge Alarm Unit has been designed specifically for use in conjunction with 15 ppm oil-water separator units and has a specification and performance which exceeds the requirements of the International Maritime Organization specifications for 15ppm Bilge Alarms contained in Resolution MEPC. 107 (49).

The unit is supplied with 2 works-adjusted alarms at 15 ppm. Other set points (10 ppm or 5 ppm) are possible and can be adjusted on site at any time by using the buttons at the front panel. If an alarm set point is exceed, the alarms are visible at the front panel and the appropriate relays are switched.

In case of malfunction the System LED at the front panel will change from blinking green to permanent red. For the data logging function the unit requires an status input from the separator. Optionally a 0(4) - 20 mA (equal to 0 - 30 ppm) signal output is available for driving a recorder or external meter.
