    Theory of Operation Tempest is a DSP (Digital Signal Processor) based, full duplex, wireless intercom system. It is a digital, point-to-point communications system, operating in 26 MHz of spectrum in the 900MHz frequency band. This band allows users to operate with no license requirements in most locations. The 900MHz band offers many benefits.
  • Page 15 because there is no system latency delay. Tempest uses advanced echo-cancellation algorithms to eliminate this echo. Wireless intercom systems are often used in high-noise environments that require special design consideration for effective operation. Tempest operates extremely well even in very high ambient noise levels. This is primarily due to specific design criteria which allow Tempest to achieve an audio dynamic range of greater than 94dB.

  • Page 56: 4-Wire (Matrix) Intercom Interface

    4-Wire (Matrix) Intercom Interface 4-Wire intercom systems use two pairs of wires to carry one full duplex channel of intercom audio - one pair for send and the second pair for receive. In addition to intercom audio, most systems have separate data lines that carry system data from the matrix to the remote devices.

  • Page 57: 2-Wire (Party-Line) Interface

    Steps to Configure a 2-Wire Intercom Connection • Adjust the Intercom Type Slide Switches to appropriate manufacturer compatible setting- RTS, Clear-Com, Bal. • Select 2-Wire connection for the appropriate channels.
  • Page 58 Auto-Null Explained In 2-Wire intercom systems, inefficiencies in the hybrid circuitries that combine or separate the send and receive audio signals onto the same pair of wires inherently cause echo. Within analog systems the echo is not noticeable, but when connected to an extremely sensitive digital system, the echo becomes more problematic.

  • Page 59: Manual Null

    Manual Null Generally, Auto-Null will adequately control the inherent echo caused by the 2-wire hybrid circuitry. However, “Manual Null” is available if there is residual echo. If echo persists after testing for at least 30 seconds: 1. Turn OFF all TALK buttons on wireless and wired equipment. Since Tempest analyzes a tone to adjust the Null characteristics, any sounds entering through the wired or wireless systems will interfere with the nulling process.
