[CA] [CA11] A57D external alarm capability

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Bucky,

Unlike the more capable E-Series Classic MFDs of this period, the A-Series Classic MFDs did not feature an alarm port/cable. While Raymarine recently introduced the A80614 Seatalkng Auxiliary Alarm Buzzer, this accessory is not designed to sound for alarms generated by an A-Series Classic MFD. Appendices A through R of the of the SeaTalkNG Auxiliary Alarm Buzzer Installation Instructions provide a comprehensive list of alarms which the A80614 SeaTalkNG Auxiliary Alarm Buzzer will suppport. While Raymarine recently introduced the Seatalkng Auxiliary Alarm Buzzer, this accessory is unfortunately not designed to sound for most alarms generated by MFDs running software prior to the latest available LightHouse 3 software (v3.10.71 at the time of this response). As indicated within its title, this product is designed to be interfaced as a spur to the system's powered and properly terminated SeaTalkng / NMEA 2000 backbone. To remotely hear alarms sounded by an Axiom/Axiom Pro/Axiom XL MFD, the MFD's Bluetooth feature may also be used to connect the MFD to a Bluetooth amplified speaker which will be located within the space where the alarm is desired to be heard. Alternatively, many owners will elect to install a low cost MFD (ex. Axiom 7 MFD with no internal fishfinder circuitry or bundled cartography) within the space where the alarm is desired to be heard. The advantage of the latter is that information concerning the nature of the alarm will be available to operator at the remote location, and it will be possible to cancel the alarm at the remote location. As indicated within its title, this product is designed to be interfaced as a spur to the system's powered and properly terminated SeaTalkng / NMEA 2000 backbone.
