KXB127
Mine Explosion-proof And Intrinsically Safe Sound And Light Language Alarm
KXB127 is mainly used for the display of safety warning words and road direction indications in underground coal mine roadways; it can be used for transportation roadway entrances, exits, three forks and many Audible and visual alarms are provided at the forks; it can also provide turn-by-turn instructions for track listing and personnel; it can also be used for corners, inclined lanes, belt conveyors, man-carriages, winches, hoists, switches, damper status and other Equipment prompts, voice prompts, fault indications, etc. where alarms and displays are required.
Working principle
A. The device is connected through the sensor opening signal (active high level, + 12V), and is analyzed and processed by the main control board and output to the display and voice parts to achieve display instructions and voice alarm functions;
B. After the device receives the signal, the relay will output a closed-point signal, which can be used to control external equipment or be used online.
Voice selection
Select the language alarm content by changing the position of the S2 four-digit DIP switch on the circuit board. Dial switches 1, 2, 3, and 4 are combined in binary mode to indicate the language number. When the end button is in the ON position, it indicates "0", otherwise it indicates "1".

Delay time selection
Select the alarm delay time by changing the position of the eight-digit DIP switch on the circuit board. The DIP switches 1,2,3,4,5,6,7,8 use a binary combination to represent the delay time. When the end button is in the ON position, it indicates "0", otherwise it indicates "1".

The delay time is calculated as follows:
(1) When bit 7 is 1, the time unit is seconds in the low delay range, and the delay time = the value represented by bits 1 to 6;
Among them, end button 1 is the lowest bit of the binary number, and end button 6 is the highest bit of the binary number.
