  • Page 3: Specification

    GENERAL The ED830 is a four zone bilge level alarm control unit designed to meet the MCA code of practice. Each of the four zones are independent from each other with completely separate circuitry, switches, fuses, lamps etc. Zone wiring is fault monitored with the aid of a 4K7Ω resistor, which must be fitted at the end of the line zone wiring in the form of a end of line float switch.
  • Page 4 It requires approx 30mm-40mm of travel of the float to cause operation of the switch. 275mm (283mm required for lid clearance) M3 mounting holes 25mm from edges.

  • Page 6 ALARM OUTPUT FUNCTIONS The ED830 has three sets of voltage free contacts for each zone. One set for the pump, if fitted. The pump must have a current consumption of less than 6A or be driven via a suitable external relay. The second set of contacts are for a low power xenon beacon which could be fitted high on the vessel (e.g top of the mast) to attract attention whilst moored etc.
