Loudspeaker communication and warning system

As a loudspeaking communication system for shafts, the system provides:

  • Simplex communication between user’s devices

  • Light and sound warning

  • Generation of warning signals and voice messages (if СUKS-6/SZ/1 monitoring and control device is available)

  • Alarm mode visualization (if СUKS-6/SZ/1 monitoring and control device is available)

  • Visual indication of selected system component duty modes (if СUKS-6/SZ/1 monitoring and control device is available)

As a loudspeaking communication system along the face conveyor, gate conveyor, or belt conveyor, the system provides:

  • Voice communication between user’s devices

  • Light and sound warning

  • Interaction with mine emergency and control communication and alarm system like ShTSI4, SAT

  • Calling to and conversing with the dispatcher (in joint operation with systems)

  • Emergency calling to the dispatcher and rescue service

  • Generation of warning signals and voice messages

  • Alarm mode visualization

  • Visual indication of selected system component duty modes (conveyor sensors, face conveyor sensors, combined machine, etc.)

  • Tripping by means of ACBs

  • Trip location (visual and voice message)

  • Work logging (storage)

  • System monitoring from the surface (if a mode is available)

Environment conditions:

  • Underground excavations and ground premises of mines and pits with the ambient of hazardous gas and/or combustible dust

  • Category I explosive mixture (methane at underground works) ambient or corrosive salty dust ambient

  • Climatic version: U5 (temperate)

  • Ambient temperature: 0°C to +35°C

  • Relative humidity: (98±2)% at (25±2)°C

  • Atmospheric pressure: (99.75±13.3) kPa

  • Dust concentration in air: max. 1500 mg/m3

  • Vibration: max. 25 Hz

  • Vibration acceleration: max. 10 m/s2

  • Mechanical impact exposure group: M18

  • Severe shock or impact: not allowed

  • Working position: vertical, with deflection by max. 15° in any direction

  • Allowable power mains voltage fluctuations: 85% to 110% of rated value

Characteristic features:

  • System components are connected to any of two trunks, gate trunk (LH) or face trunk (RH), from CUKS-5BX controller, of serially, from СUKS-6/SZ/2 controller (if the system is used for loudspeaking shaft communication)

  • Number of devices (network nodes) in the LH or RH trunk: max. 40

  • Number of devices (network nodes), if the system is used for loudspeaking shaft communication: max. 40 per trunk

  • Total number of loudspeaking devices in two trunks: max. 50

  • Device (network node) feed voltage: 12.5~15.8 VDC
