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 tted at the end of the line zone wiring in the form
of a end of line oat switch. Both on and off delay times can be adjusted for each zone giving a pump run on facility and avoiding

nuisance alarms due to movement of the vessel.

Please note it is the responsibility of the end user to test the equipment regularly to ensure correct operation.

SPECIFICATION

Power input 12VDC or 24V DC

Typical Current consumption per zone:
in non alarm condition = 20mA

in alarm condition = 25mA

with short circuit wiring fault = 70mA

Ambient temperature range -25C to +55C

Note sounder, beacon and pump consumption not included.
