GPSMAP 4000/5000 Series Installation Instructions
Wiring to an optional Alarm
The GPSMAP 4000/5000 series chartplotter can be used with a lamp, a horn, or both, to sound or flash an alert when the chartplotter displays a
message. The alarm does not need to be wired for the GPSMAP 4000/5000 chartplotter to function. The alarm circuit switches to a low-voltage
state when the alarm sounds. The maximum current is 100 mA, and a relay is needed to limit the current from the chartplotter to 100 mA. To
select between visual and audible alerts, install a switch.
