Kxb18 Intrinsically Safe Voice and Acoustic-optic Alarm for Mines

Usage and Scope of Application

 KXB18 Mine Intrinsically Safe Voice and Sound & Light Alarm is an intelligent alarm device specially designed for the underground coal mine environment. It has voice prompt and high - intensity light alarm functions, supports multi - channel signal input and various communication methods, and is suitable for scenarios such as underground gas over - limit warning, emergency shutdown warning, restricted area management, roadway traffic safety, status indication of large equipment, emergency evacuation guidance, voice broadcast and instruction issuance. 

Main Functional Features 

· Multi - mode alarm: Supports three - channel signal input and up to 128 combined alarm modes, flexibly coping with various alarm scenarios;

· Customizable voice: It has a built - in voice synthesis unit and supports setting the broadcast content through software or the host computer;

· Dual communication interfaces: It is equipped with RS485 and CAN dual communication interfaces, supporting remote control and status query;

· High visibility and loudness: The visible distance of the light signal is ≥20m (in the dark), and the sound alarm loudness is ≥85dB(A);

· Intrinsically safe explosion - proof design: It complies with the mine intrinsically safe explosion - proof standard and is suitable for explosive gas environments;

· High protection level: IP67 protection, dust - proof and waterproof, suitable for harsh underground environments;

· Low - power design: The working current is ≤300mA, energy - saving and reliable;

· Convenient installation: It uses a threaded installation method and is equipped with an aviation plug, making wiring simple and convenient.
