Applications of mining intrinsically safe electronic horns:
/ Mine intrinsically safe electronic horns are suitable for use in mine underground sidewalks, locomotives, and parking lots. The electrical signal is converted into a sound signal through the preamplifier, thereby realizing the warning whistle function and providing guarantee for safe operation.
Environmental conditions:
The speaker should work normally under the following conditions:
) Temperature: ℃～+℃

b) Relative humidity % (+℃
/> ) Air pressure: ~
) Underground coal mines with explosive mixtures of methane and coal dust.

Wiring method
Power input terminal: DC power supply has no polarity
Button control terminal: No polarity. Note:
It is strictly prohibited to open the cover while power is on. The power supply must be cut off during installation or maintenance.
When installing, make sure the screws on the wiring and terminal blocks are tightened and not loose.
In the wire introduction or extraction equipment, you should first determine whether there is a sealing ring flat gasket, and then tighten the horn mouth.
During maintenance and repair, it is strictly prohibited to open the cover while the power is on! It is strictly prohibited to damage the explosion-proof surface! During maintenance, the electrical parameters, specifications and models of intrinsically safe circuits and components related to intrinsically safe circuits must not be changed. It is not allowed to use the ground core wire of the cable as an intrinsically safe control loop
.
