KXH0.2 (0.6) 127 (36)-type combination of sound and light signal devices 
 Combination of sound and light signal control signal KXH127 combination of sound and light signal device type 
 I. Overview 
 KXH0.2/127 type of sound and light combination of signal devices, mainly for coal mine with coal dust and explosive gases in the workplace. Supply voltage of 127V, the power connection through the realization of carrier intercom communications. Mining moisture by the speaker and the highlight sound and light emitting diode signal. 
 The product set dot button, explosion-proof lights, explosion proof bells, three terminal box as one equipped with explosion-proof wiring chamber dot button, and three outlet ports, replaced the buttons and links RBI junction box, with bright light diodes and replaced mine explosion proof lights and speakers proof bell. 
 Second, the normal working conditions 
 a, explosion-proof type: Flameproof and Intrinsically Safe, Explosion-proof mark: Exd [ib] I; 
 b, Atmospheric pressure: 80kPa ~ 106kPa; 
 c, ambient temperature is not higher than +40 ℃, not less than 0 ℃; 
 d, the ambient air relative humidity less than 95% (+25 ℃); 
 e, can be used for methane or coal dust explosion hazards in mines; 
 f, in the absence of significant local rock and shock and vibration;
