DIS5 Loudspeaker Unit

A range of speech communications systems are available for surface and underground use to provide mine or plant wide loudspeaker communications, either directly or via a purpose built control room switchboard. Systems can be designed to incorporate audible alarms or voice messages to warn of dangerous conditions or they can provide pre-start warning for conveyors or other machinery.

A typical underground system would consist of power supply, a console unit and a number of loudspeaker amplifiers, all interconnected via a single 4 core cable. Each amplifier unit contains its own rechargeable battery unit so that in the event of a mains power failure, communications can be maintained for extended periods. Systems can be connected together directly or via a control room console.

Underground units are certified to European Standards for use in underground coal mines. For surface preparation plants and other arduous environments, robust loudspeaker systems are available with various configuration options including remote high output speakers, handset units and three channel systems. Loudspeaker communication systems are high output, low maintenance and low cost leading to a safer and more efficient workplace.
