A system assessment is essentially a comprehensive overview of the structure, layout and functionality of any given system. In the world of electrical contractors, we are more often than not referring to networking systems, even though the same methodology applies to electrical systems.
Moving toward standardization Certain elements of the installation of wiring/cabling for residential low-voltage systems are on their way to becoming “standardized,” or at least looked at as benchmarks. Here is a closer look at some guidance for a “standards compliant” installation.
If you’re involved with security systems (procurement, design or installation), this article looks at what market segments they may fall in and where you can go to learn more about the “standards” that apply to a product or its installation.
