8. Connecting the horn module
The first step of connecting the Dockmate to the boat is by connecting the horn
module.
Please note that when depressing the 'Horn'-button on the single and twin
transmitter, there will be a delay time of about 0,6 seconds.
The Dockmate Receiver may only be connected directly to the boat's
horn button when the boat's horn circuit has a built-in relay.
When the horn button is big, bulky and has very thick wire, that suggests
that no relay is used on the boat. In that case, wiring the Dockmate the
standard way can cause wires or relays to burn, since it can only switch up to 2-3A.
For boats without a built in horn relay, an additional relay must be used.
Dockmate can supply:
-
"09.03.02 – External Horn Relay – 12V"
-
"09.03.03 – External Horn Relay – 24V"
Alternatively, you can use a generic 12V relay (or 24V relay, depending on the boat).
You can easily check the need for an additional relay by using a multimeter.
Disconnect one wire from the horn button and set your multimeter for amps (10 or
20A range). Connect it as shown in the image below, and press the horn. When the
current is bigger than 3A, an External Horn relay has to be used.
