Garmin GPSMAP 4012 - Marine GPS Receiver Installation Instructions Manual
Wiring to an Optional Alarm
The GPSMAP 4000/5000 series unit can be used with a lamp, a horn, or both, to sound or flash an alert when the unit displays a message. The
alarm does not need to be wired for the 4000/5000 unit to function. The alarm circuit pulls low when the alarm sounds. The maximum current is
100 mA, and a relay is needed to limit the current from the unit to 100 mA. A switch can be installed to select between visual and audible alerts.
