　　XJH127Mining sound and light signalerProduct Introduction

　　The communication sound and light signal device integrates a point button explosion-proof signal light explosion-proof electric bell three-way junction box, replacing the point button and three-way junction box, and replacing the explosion-proof light and explosion-proof electric bell with a high brightness light-emitting diode and a mining moisture-proof speaker. The shell of the speaker is made of moisture-proof material, which has the characteristics of stable performance and long service life. Traditional sound and light signal devices are installed on the walls of mining areas. Generally, the environment in mining areas is dark and humid, and there is a lot of dust. Long term exposure to damp and dusty environments can damage the sound and light signal device. The mining communication sound and light signaler integrates a point button, explosion-proof light, explosion-proof bell, and three-way junction box. A point button is installed in the explosion-proof junction box, and there are three outlet ports, replacing the point button and three-way junction box. The explosion-proof light and explosion-proof bell are replaced with high brightness light-emitting diodes and mining moisture-proof speakers. Mainly used in workplaces containing coal dust and toxic gases underground in coal mines. The power supply voltage is 127V, and there are also 36V mining communication sound and light signalers that achieve carrier intercom communication through power connections. Realize sound and light signals through mining moisture-proof speakers and high brightness light-emitting diodes.

　　XJH127Mining sound and light signalerWorking Principle:

　　Sending signal (dotting): Press the dotting button to trigger its own oscillator, enter the power amplifier of this station, and trigger the dotting alarm of this station. The oscillation signal of this station is loaded onto the communication line, and the electronic switch of each online signal is turned on to load the signal into the power amplification circuit of each online signal, thereby achieving dotting to each online device, and indicated through the speaker and high brightness indicator light.
