海安会MSC.339(91)决议《国际消防安全系统规则》（FSS）修正案

Resolution MSC.399(91) Amendments to the internationl code for fire safety systems (FSS CODE).

它将指针式压力表与电子声光报警组合在一起，当气瓶内压力降至5.5±0.5MPa时，报警器发出持续蜂鸣报警声和红、白强光闪烁信号。与传统的气动哨笛声讯报警器相比，电子声光报警器具有报警器、光同时报警功能、不同压力段灯光提示功能，以保证呼吸器使用人员或现场监护人员通光多种提示方式得到残余气压信息和报警信号，从而有效保障使用人员呼吸和安全撤离。

It combines a pointer-type pressure gauge and the electronic audible and visual alarm into one unit:when the cylinder pressure drops to 5.5 + 0. 5MPa, the electronic audible-visual alarm sends out alarming buzzes greater than 90dB, and also emits a white flashing light and red flashing light signal. Compared with the traditional pneumatic whistle alarm, the electronic audible-visual alarm has two alarming features:sound alarm and flicker alarm to ensure the respirator user and the supervisor to obtain the air residual pressure information and alarming signal through a variety of ways, so as to effectively ensure the breathing and security of the user.

电子声光报警器

Electronic Audible and visual Alarm

 1. 当气瓶压力大于10MPa时，指示灯为绿色。

1. When the cylinder pressure is greater than 10MPa,the air pressure indicator light turns green in constant status.

 2. 当气瓶压力小于10MPa时，大于6MPa时，指示灯会黄色。

2.When the cylinder pressure is greater than 6MPa but less than 10MPa,the pressure indicator light turns yellow in constant status.

3.当气瓶压力小于6MPa时，指示灯为红色，并闪光；周围4只白色灯同时闪烁。

3.When the cylinder pressure is less than 6MPa,the pressure indicator light turns red in flashing status

  4.闪光暂停时的状态。

4.State flash during pause.

B. 气瓶内气压大于6MPa小于10MPa时，气压指示灯为黄色常亮状态；

b.When the cylinder pressure is greater than 6MPa but less than 10MPa, the pressure indicator light turns yellow in constant status;

C.气瓶内气压小于6MPa时，气压指示灯为红色强光闪烁状态。

C.When the cylinder pressure is less than 6MPa, the pressure indicator light turns red in flashing status.

电量指示灯Power indicator light

当电池电量只剩下总电量的20%，电源欠压指示灯（黄灯）开始常亮。

When the battery is only 20% of the full power, the under voltage indicator light(yellow) turns on in constant status.

骨传导

Bone Conduction Communication Unit (BCCU)

骨传导是将佩戴人员的对话语音输送给对讲机、并将对方的通话送到耳机的设备。

  正常使用呼吸机时，佩戴人员讲话声音受面罩的阻隔，难以清晰传输到面罩外，并且面罩内有呼吸产生的气流声，干扰讲话声音的传输。骨传导设备不受这些外因的限制，将语音振动产生的信号拾取后送给对讲机转成音频发射出去；PPT按键设计为超大按键，即使穿戴厚大的防护手套也能操作，方便使用人员操作；耳机设计安装在耳朵旁边，消除了对讲机声音从腰间传到耳朵的距离，极大减少环境环境杂音对听力和通话质量的影响。当与对讲机有线连接后，与对讲机的功能相同，按下骨传导的PPT按键，即向对方送话，松开按键，则接受对方的讲话。

BCCU is a device of the wearer's dialogue voice transmission to the intercom, and the other person's calls to the headset.

During normal use of a respirator, it is difficult to clearly transmit the sound outside with the barrier of mask and the sound of breathing airflow generated within the mask, which is interfering transmission speech sounds. BCCU is not limited to these external factors, for the vibration signal of voice can be collected and sound signal outside through inter-phone PTT button design as large buttons, even if Heavy Wear protective gloves can operate, easy to use and operate; Headphones are designed to be installed next to the ear, eliminating the sound distance between the ears and the waist, greatly reduce the impact of environmental noise on hearing and call quality. When connected to the wired inter-phone, same operation with the itself, that press the PTT button on the BCCU, to communicate with other person, and release the button, to accept other's speech.
