  4. Operational modes 工作模式 • Automatic (Automatically brought into operation whenever the ship’s heading or track control system is activated and inhibited when this system is not activated) • Manual ON (In operation constantly) • Manual OFF (Does not operate under any circumstances) • Third stage alarm （If not reset, the BNWAS should additionally sound a third stage remote audible alarm at the locations of further crew members capable of taking corrective actions 90 s after the second stage remote audible alarm is initiated. In larger vessels, the delay between the second and third stage alarms may be set to a longer value on installation, up to a maximum of 3 min, to allow sufficient time for the back-up officer and/or Master to reach the bridge.) • 自动模式（船舶航行控制系统运行时自动控制该系统处于持续工作状态） • 手动开启（系统进入持续工作状态） • 手动关闭（系统处于关闭状态） • 灯光提示 （系统启动后，报警计时器开始计时，计时时间超过设定时间（3~12分钟可调）后，系统输出灯光提示信号） • 一级报警 （系统输出灯光提示后，如果没有被复位，系统在15秒后输出一级报警声音信号（桥楼区域）） • 二级报警 （系统输出一级报警后，如果没有被复位，系统在15秒后输出二级报警声音信号（后备值班驾驶和船长区域）） • 三级报警 （系统输出二级报警后，如果没有被复位，系统在90秒（对于大型船舶，可以最大设置为180秒，以便二级报警后，后备值班驾驶和船长能及时赶到桥楼进行报警复位）后输出三级报警声音信号（后备值班驾驶和船长区域）） • Alarms & indications functions 报警及指示功能 • Visual indication (Once operational, the alarm system should remain dormant for a period of between 3 and 12 min (Td). At the end of this dormant period, the alarm system should initiate a visual indication on the bridge.) • First stage alarm (If not reset, the BNWAS should additionally sound a first stage audible alarm on the bridge 15 s after the visual indication is initiated.) • Second stage alarm (If not reset, the BNWAS should additionally sound a second stage remote audible alarm in the back-up officer’s and/or Master’s location 15 s after the first stage audible alarm is initiated.)

  5. Reset functions 复位功能 • It should not be possible to initiate the reset function or cancel any audible alarm from any device, equipment or system not physically located in areas of the bridge providing proper look out. • A continuous activation of any reset device should not prolong the dormant period or cause a suppression of the sequence of indications and alarms. • Communication interfaces 通信接口 • Additionally, the BNWAS shall provide an interface according to IEC 61162-1, ALR sentence. • 系统提供满足to IEC 61162-1 标准要求的通信接口 • Security 安全 • Selecting the Operational Mode and the duration of the Dormant Period (Td) be security protected so that access to these controls should be restricted to the Master only. • 复位功能只能设置在桥楼能够正常监视到区域 • 复位功能只在按钮被按下的瞬间被触发，当复位按钮持续被按下时，计时器将在被复位一次后重新开始计时。 • 系统工作模式转换及系统参数修改功能受密码保护，防止非被授权人员进行操作。 • Emergency call 紧急呼叫 • On the bridge to immediately activate the second, and subsequently third, stage remote audible alarms by an ‘Emergency Call’ push button. • System failure alarms and indications 系统故障报警 • If a system failure (PLC failure and HMI panel failure) or power supply failure to the BNWAS is detected, this should be indicated and extend by external interface. • 值班人员能在桥楼启动紧急呼叫按钮触发二及报警，并按正常时序触发三级报警。 • 系统具有完备的自检功能，系统故障时，能输出故障报警信号。

  6. Main standards 主要设计标准 • MSC.128(75)-Performance standards for a bridge navigational watch alarm system(BNWAS) • IEC62616-Maritime navigation and radio communication equipment and systems • IEC60945- Maritime navigation and radio communication equipment and systems –General requirements –Methods of testing and required test results • Specifications 技术参数 • Main supply voltage: 220VAC,50Hz/60Hz • Backup supply voltage :24 VDC • Power: 50 watts • All the test of components of BNWAS according to the following requirements: • 主电源：220VAC,50Hz/60Hz • 备用电源：24 VDC • 电源功率：50 W • 系统及设备满足以下标准要求
