KTZ127 type acousto-optic annunciator model acousto-optic annunciator affordable price

Type acousto-optic annunciator Overview of the acousto-optic annunciator
The type mine explosion-proof and intrinsically safe communication acousto-optic annunciator (coal safety certificate number: B) is mainly used in workplaces containing coal dust and explosive gases underground in coal mines . It is suitable for signal communication in coal mine inclined tunnel lifting, belt transportation, etc. It can also be used as a direct telephone line between the winch room and the wellhead. The sound and light signal is realized by a mine-type moisture-proof speaker and a high-brightness light-emitting diode.
Structural features of the sound and light annunciator
The mine-type explosion-proof and intrinsically safe communication sound and light annunciator integrates a dotting button, an explosion-proof lamp, an explosion-proof bell, and a three-way junction box into an explosion-proof wiring cavity. It is equipped with a dot button and has three outlets, replacing the dot button and three-way junction box. High-brightness LEDs and mine-use moisture-proof speakers replace explosion-proof lights and explosion-proof electric bells. Carrier intercom communication is realized through power connection.
The mine explosion-proof and intrinsically safe communication audible and optical annunciator has simple wiring, easy maintenance, and easy use. The communication adopts frequency modulated power carrier, strong anti-interference ability, long transmission distance, and good communication effect. The product movement Epoxy encapsulated, moisture-proof, shock-proof, and long service life.
