KTH106-1Z type mine intrinsically safe automatic telephone 
 Telephone automatic telephone Intrinsically Safe Mine Telephone 
 KTH106-1Z type mine automatic telephone intrinsically safe standard in accordance with Q/HX001-2007 production. Pulse audio is compatible with the dual telephones, and associated mining equipment HDK telephone couplers, and output signals meet the requirements of the dispatch or switch can be composed of Coal Mine Safety Communication System network. Can be widely used in explosive gas environments. The explosion marked as "Exib Ⅰ". 

 Features 
 1, the phone casing is aluminum, good looks, high mechanical strength. 
 2, using the new key number plate. 
 3, telephone with international standard integrated circuit within the circuit, has made accurate number, the call clear, stable and so on. 
 4, with two-tone and pulse Fat No Fat No function (switch factory common dual audio). 
 5, the whole shock, moisture, small size, light weight, strong, durable, easy to maintain. 
 Main technical parameters 
 1, conditions of use 
 Ambient temperature: -10 ℃ - +40 ℃; 
 Relative Humidity: ≤ 95% (+25 ℃ pm) 
 Atmospheric pressure: (86-106) kpa 
 Related Equipment: HDK coupler 
 2, Dimensions mm: 112 × 290 × 122 
 3, Weight: 2.5kg 
 4, the communication distance: ≤ 10km, cable model specifications for the MHYV1 * 2 * 7/0.37. 
 Help 
 1, the telephone line connected to the input HDK-type coupling the output of the whole (couplers should be located in safe areas) and the coupler input termination consistent with the input signal or switch to dispatch. 
 2, when the dispatcher or switch signal format for the pulse signal, the phone open, the switch "on the pulse" position. 
 3, pick up, then hear the dial tone to dial-up, when the called party is busy, you can hang up first, and then re-hook to dial.
