Safety Sign Number: MAJ070033
Validity period: July 23, 2010 to July 23, 2015
Scope of application: Strictly use in accordance with relevant regulations on coal mine safety.
Execution standards: GB3836-2000, MT287-1992, Q/HS012-2006

Features of KTZ104-127 acousto-optic signaler:

1. Signal transmission: Press the explosion-proof signal button on this unit to send signals (dots) to this unit and all connected units
2. Signal reception: Each connected unit can receive signals sent by any one, emitting sound signals greater than 85dB through speakers and visible light signals within 30 meters through light-emitting diodes
3. Simplex intercom: This device achieves power line carrier intercom function without changing the existing power supply and wiring method

Scope of application:
This communication sound and light signaler is mainly used in workplaces containing coal dust and explosive gases underground in coal mines. The power supply voltage is 127V. Carrier intercom communication is achieved through power connection. Realize sound and light signals through mining moisture-proof speakers and high brightness light-emitting diodes.
