KXB127 Mine acousto-optic voice alarm

Overview of KXB127 explosion - proof and intrinsically safe language Acousto-optic alarm

KXB127 flameproof and intrinsically safe language acousto-optic alarm is mainly used in places containing explosive gases in underground coal mines. It can be used for striking points and acousto-optic alarm at the entrance, exit or three fork of transportation roadway, and also for acousto-optic alarm of shaft hoisting. KXB127 flareproof and native safe language acousto-optic alarm not only has the function of doting and light indication when doting, but also has the voice prompt, which makes it conform to the requirements of the latest coal mine Safety regulations.

KXB12 Mine natural security type sound and light alarm USES the environmental condition

A) Ambient temperature: 0℃ ~ +40℃

B) Average relative humidity: ≤ 95% (+25℃)

C) Atmospheric pressure: 80kPa ~ 106kPa

D) Place of use: coal mine Wells with explosive mixture of methane and coal dust, but without corrosive gas that destroys the insulation

Structural features and working principle of KXB12 mine intrinsic safety acousto-optic alarm

The alarm has two Chambers, separating the detonation chamber and the ampere chamber. The circuit adopts the integrated voltage comparator, the electro-optic coupler with high inspiration and modular design. Overall layout reasonable, small volume, light weight.

The alarm has two states, one is standby state; Second, alarm status. When standby, the green light is always on, the red light flashes when the alarm is given, and the loudspeaker sends out the language warning of "no pedestrians are allowed when driving". The operator presses the button and its normally open contact closes, the alarm internal conduction, at this time all in the road alarm is driven to send out the dot signal. The operator shall continuously operate the button for two or more times, the time interval shall not exceed 3 seconds (adjustable), the alarm shall change to the alarm state, and the alarm state shall be maintained for a maximum of 15 minutes (adjustable time). During the alarm process, the operator presses the button once, the alarm stops, and the alarm changes to standby state. The device can also be used in combination with an electric bell in the same way.

KXB12 mine natural security type sound and light alarm installation

Users can choose mine rubber-sheathed cable with an outside diameter of 10mm according to their needs. Wiring is shown in the figure.

Precautions for installation;

The power lead is connected to terminals A, B, C and D;

Fault analysis of KXB12 Mine intrinsic safety Acousto-optic alarm

Silent, lightless should check the emergency power supply of the insurance pipe or replace the control panel.

Red light flashes without language alarm, speaker lead is broken, speaker is bad or language board is bad.

Long-term alarm control panel is broken.
