Important components of an Intercom and PA\/GA system, which are critical and essential for the proper functioning of the system, should be redundant to increase system reliability.<\/p>\n

In order to meet the highest safety demands, INDUSTRONIC provides different redundancy concepts. These can be adapted to customer and site requirements and guarantee optimum protection and safety for personnel and machines.<\/p>\n

INDUSTRONIC\u2019s redundancy concepts are often used in challenging environments, e.g. offshore applications, but also in other industrial environments, where absolute reliability of communication and warning systems has top priority.<\/p>\n

In this and in later blog posts I would like to give an overview on the different redundancy concepts INDUSTRONIC offers. This first post focuses on Component Redundancy<\/b>.<\/p>\n

At INDUSTRONIC, we distinguish between two different types of component redundancy concepts: N+1 Redundancy<\/b> and
1+1 Redundancy<\/b>.<\/p>\n

N+1 Redundancy<\/span><\/b> is defined as follows:<\/span><\/p>\n

For this redundancy concept one or several<\/b> active components (N)<\/b> are backed by exactly one<\/b> backup component (+1)<\/b> in hot standby mode. As soon as an active component fails, the backup component takes over the complete functions of the defective component. The failure of a second active component cannot be compensated.<\/p>\n\n\n

\"N+1_Redundancy\"<\/a><\/figure><\/div>\n\n\n\n

1+1 Redundancy<\/strong> is defined as follows:<\/p>\n\n\n\n

For this redundancy concept one<\/strong> active component (1)<\/strong> is backed by exactly one <\/strong>backup component (+1)<\/strong> in hot standby mode. As soon as an active component fails, the corresponding backup component takes over the complete functions of the defective component. This way several failures can be compensated.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"1+1_Redundancy\"<\/a><\/figure><\/div>\n\n\n\n

When comparing these two component redundancy concepts you will realize that N+1 Redundancy provides a standard backup protection, whereas the 1+1 Redundancy concept guarantees increased availability of components, as even several component failures can be compensated at the same time. We at INDUSTRONIC will assist you to find the solution that fits your requirements the most.<\/p>\n\n\n\n

INDUSTRONIC\u2019s component redundancy concepts are used in the following three basic redundancy concepts and can also be combined with each other:<\/p>\n\n\n\n

  • Single System with N+1 Components<\/li>
  • Duplicated Control System (hot stand-by operation)<\/li>
  • A+B System (shared operation)<\/li><\/ul>\n\n\n\n

    Learn more about them and the possible combinations in my follow-up posts coming soon.<\/p>\n","protected":false},"excerpt":{"rendered":"
