1.6.8 Lamp and Horn Connections
The device can be used with a lamp, a horn, or both, to sound or flash an alert when the
chartplotter displays a message. This is optional, and the alarm wire is not necessary for
the device to function normally. When connecting the device to a lamp or horn, observe
these considerations.
• The alarm circuit switches to a low-voltage state when the alarm sounds.
• The maximum current is 1 A, and a relay is needed to limit the current from the
chartplotter to 1 A.
• To manually toggle visual and audible alerts, you can install single-pole, single-throw
switches.
