Deckma OMD-2005 15PPM Bilge Alarm Unit

Deckma OMD-2005 15PPM Bilge Alarm Unit

The OMD-2005 15PPM Bilge Alarm Unit is specifically designed for use with 15 ppm oil-water separator units, surpassing the requirements set by the International Maritime Organization’s specifications for 15ppm Bilge Alarms (Resolution MEPC. 107 (49)). This alarm unit provides enhanced performance and reliability. The unit is equipped with two pre-adjusted alarms set at 15 ppm, with the flexibility to adjust to other set points such as 10 ppm or 5 ppm as needed. Alarm conditions are indicated on the front panel, and corresponding relays are activated accordingly. In case of a malfunction, the System LED changes from blinking green to solid red, and the appropriate relay switches. For data logging purposes, the unit requires status input from the separator and a feedback signal from the valve position limit switch. Additionally, it offers a 0(4) – 20 mA signal output, equivalent to 0 – 30 ppm, for external metering or recording purposes.

The OMD-2005 15PPM Bilge Alarm Unit employs an optical sensor array that measures light scattered and absorbed by oil droplets in the sample stream. These signals are processed by a microprocessor to provide linearized output. The microprocessor continuously monitors the sensor components and associated electronics to maintain calibration accuracy under varying environmental conditions. Key features of the unit include its robust construction, automatic voltage selection, solid suppression capability, low maintenance requirements, easy installation, constant readiness, watertight housing, and adjustable settings accessible through the menu. The unit’s alarms can be individually set, and the time delays for the alarms can be adjusted as well.
