Home Automation Safety

X-10 Home Automation is very adaptable to the "Do it Yourselfer", and all of the products are UL listed and simple to install. However as the enthusiast attempts to expand the home automation system, more complex interface techniques may become necessary. Much information is available on products and these applications, but not much is mentioned about safety. Promotion of the technology should also include safety awareness. It's one thing to make an application work, yet is it safe under varying circumstances? If your goal is to have a complete home automation system, it may be sensible to let a professional, licensed and insured dealer perform the design and installation of your system. This allows you to create the type of home you want and not worry about the insurance, warranties or technical ramifications of such project changes to your home. Despite these cautions most DIY's will persist, so with that in mind and the lack of available documents on the subject I have included parts from our company safety policy. Legal details have been omitted and amended with generic references to highlight some areas of concern. - Think about safety!
In addition to following the National Electric Code, local codes and using UL Listed components for all electrical device installations, it should be the intent of the installer & programmer to test each item for the intended use. Variations that could occur in the following: including but not limited to; the surroundings, time frame, situation (i.e., Emergencies, stress, etc.), unexpected failure of associated device/s or power, misuse by children, pets or persons unfamiliar with system and combinations of the preceding. Each event scenario should successfully pass or allow a safe outcome if any of the following conditions occurs affecting the logic or hardware of the system.
A label such as the one shown below should be attached in a location visible to anyone attempting to service, or modify devices controlled directly or indirectly by the automation system. The automation company should be prepared to supply the interface diagrams and any corresponding information, for cost of reproduction, protection of proprietary circuits, etc.
THIS DEVICE IS ATTACHED TO A CENTRAL HOME AUTOMATION SYSTEM AND SHOULD BE SERVICED ONLY BY AUTHORIZED SERVICE PERSONNEL FAMILIAR WITH SUCH SYSTEMS.
NAME & ADDRESS OF PERSON/COMPANY INSTALLING LABEL
This demonstrates the type of efforts you or your automation company should use to safely install and program your home automation system. Although this may not be enough to prevent unexpected and/or dangerous circumstances from occurring due to some unforeseen reason, it is certainly a step in the right direction.
