Time really makes me feel uncomfortable to come to the strange city of Liu
2013 National Day is happy, happy, happy, Hangzhou is so far away, this year, I can only fight alone in the strange city of Liu, the feelings of the family are all need to face the good afternoon, when Mr. Zhu accompanied the National Day, the mountain road is so Long feeling happy

KXH18 mine intrinsically safe acousto-optic annunciator is a mine intrinsically safe type of broadcast signal communication and sound and light alarm device, suitable for underground coal mines with gas and coal dust explosion hazard environment. The annunciator can self-expand communication communication and dot signal communication system, and can also accept external control signals.
Sound and light alarm signal can be issued for equipment start warning or alarm.
The main technology refers to the rated working voltage: DC18V
Rated operating current: ≤ 275mA
3. Intrinsic safety parameters:
Ui: DC18V; Ii: 20mA;
Ci: 0uF; Li: 0mH
Internal battery pack power supply: working voltage: DC7.4V; working current: ≤275mA; Uo: DC8V
Io: 1.4A
The battery of the annunciator is
The 18650 lithium manganate type 1.4Ah battery consists of two sections with built-in current limiting resistors. It is potted with epoxy resin and has a package thickness of 20mm.
Electroacoustic performance call mode: half-duplex intercom;
Dot signal mode: single tone sound and light signal; alarm signal mode: single tone alternate sound and light signal; sound intensity signal: sound intensity should be ≤ 85dB (A); light signal: light signal is red, light signal visibility is 20m in the dark visible.
The basic function receives the signal: the annunciator has the function of manually transmitting and receiving signals and can realize half-duplex intercom.
Call and Ride Distance: The distance between the two annunciators is 500m.
When used in conjunction with the belt conveyor integrated protection device, the annunciator has an early warning function.
Use amplified broadcast: press the annunciator talk button and scream, all other phones along the line will be amplified and the indicator light will be on.
Half-duplex session: When a call is needed between two annunciators, one party presses the talk button and calls, and the other annunciators along the line amplify the broadcast, and the indicator light is on. To listen to the other party's answering speech, the unit releases the speech button and can hear the amplified signal from the other party's phone.
Baba touch signal contact: press the signal button of the annunciator, all the annunciators along the line will send a dot signal, the indicator light is on. The number of times of betting and the time of sound can be agreed upon by themselves.
Warning alarm: all the annunciators along the line after the start warning alarm or other alarm control signals from the main control unit are fed into the annunciator
