The AIS requires that an alarm output (relay) must be connected to an audible alarm device
or the ships alarm system, if available.
Alternatively, the BIIT (built-in integrity test) alarm system may use the alarm messages
output on the presentation port (ECDIS Port Channel 5), provided the ECDIS alarm system is
connected and AIS compatible.
