7. Audible Alarm Devices
7.1 General
Audible Alarm Devices include buzzer and sounders.
For information on configuration, refer to chapter 10.6.8.
7.2 Sound Pressure Level
The sound pressure level for the sounder can be configured to High
level or Low level.
For information on sound pressure level settings, refer to Technical
Specifications, chapter 4.4.
7.3 Sound and Pulse Patterns
The sound (tone type and frequency) and the pulse pattern for a
buzzer/sounder can be configured.
The sound pattern consist of 16 bits/timeslots, where each bit
specifies if the sound should be ON or OFF during that timeslot. A
timeslot lasts for 0.5 or 1 second (configurable). In addition, there is a
repeat delay where the last bit in the sound pattern is held in its state
for the number of seconds specified in the repeat delay bit.
Technical Specifications, chapter 4.3, provides an overview of the
standard tone types/frequencies and corresponding sound patterns
that are available.
In addition, several sound patterns for the standard tone
types/frequencies can be configured to meet other user
requirements (for example, maritime general emergency signal, 7
short, 1 long). Refer to Configuration, chapter 10.
