Absolutely, and highly recommended. There are a couple of ways to do this. • The simplest is to connect another external output. Be sure that the siren will only draw 100mA (1.2watts) MAX and can run off the same voltage that the Console is plugged into. • If the external relay is not an option then you can run the second piezzo alarm in PARALLEL with the External alarm supplied with the kit. The supplied piezzo alarm draws about 20mA so the second alarm can now only have 80mA to work with. Be really careful with the installation. If it goes wrong and the main alarm is compromised then people’s lives are at risk. NOTE: Most electronic shops will sell a suitable piezzo siren as it is used for burglar alarm systems. Ask for a very low current “piezzo” alarm. If you only have a high current alarm or light then you will need to use a relay to boost the current to the alarm. Talk to a good marine electrician.
