STRUCTURED PRE-WIRE & SMART HOME AUTOMATION

PRE-WIRED STRUCTURED CABLING

The term 'pre-wiring' refers to the installation of cables and wires during a new home's construction. It includes the AC electrical wiring, as well as the low voltage, home systems cabling.

Not so long ago, the majority of homes were wired with little more than the AC electrical power-lines, a few phone lines, and a few TV cables. Times have changed. Electrical and security system contractors routinely install low voltage communication cabling for a wide range of smart home systems. Of course, the new technology does still, for the most part, require connection to the same old AC power line; but some unique and highly specific requirements must also be met.

If you're considering opting out of pre-wiring based on the wide availability of wireless devices today, remember that, despite industry pushes toward standardization, many wireless devices still use proprietary communication protocols, making them incompatible with other manufacturer's products. Partly for this reason, most home systems products are designed with structured wiring in mind. Remember also that pre-wiring is a permanent upgrade to your home, increasing its value at sale time.

Some of the home systems that require pre-wiring are security; home theater and entertainment; phones, door-phones and intercoms; PC and internet networks; surveillance cameras; driveway vehicle detection; communicating thermostats; motorized window treatments; entry systems; and irrigation systems. In addition to installing access ports for these systems, you should also decide upon at least two locations for centralized controls, i.e., one in the living room and one in the master bedroom.

The pre-wiring of an average size home entails the running of miles of cables and usually requires several days to few weeks for two installers to complete. The cost of low voltage pre-wiring varies, depending in some measure upon the number and length of cable pulls, as well as the number of terminations, but you can expect a range of between $2000 to $7500 for medium size homes, to well above that for larger homes.

This Structured Pre-Wire Plan is intended only as a general frame of reference, and should be altered to meet your specific requirements in accordance with industry practices identified in the Consumer Electronic Bus standard, which defines how information should travel throughout the home. Compliance with these guidelines insures that the residence will be pre-wired for all future needs. Z-COMM takes the time to write up a scope-of-work and, if possible, to accurately markup the builder's floor plans. And specify where in each room you want the cable terminations, as well as the type of jacks and color of wall plates to be used at each termination. All cables running into the home control distribution center will be labeled with a room name and function. Lastly, all cables will be tested for continuity to ensure there are no shorts, opens, mislabels, or incorrect runs.

MDF (main distribution area)
should be established in an area adjacent to the electrical service panel in the basement, garage or service area. A 4X6' backboard should be installed to secure the prewired cabling to their appropriate positions in preparation for the installation of the security, cable/satellite distribution, phones, PC/Internet network, audio distribution

Two cable runs of RG6 quad shield coaxial cable should be "home run" from each applicable room or area back to the MDF. RG6 cable is used for cable modems, cable/satellite, DVD, & video cameras. The quad shielding on coaxial cable insures a minimum loss of signal quality even if the cables are routed out side or around power wiring.

Two or more cable runs of Category 5E cable should be "home run" from each room planned with a phone, PC, system wall controllers, digital audio controls, thermostats, IR receivers, and cameras back to the MDF, Category 5 enhanced cable consists of 4 pair of twisted wires. The cable is immune to electronic noise and is tested and certified to communication speeds that far exceed the speed of our home networks. We suggest using different color cable for each application to easily identify cables in a bundle.

High quality jacketed 14 and 16 gauge stranded speaker wire should be pre-wired to each of the rooms and exterior areas of the home identified with speakers and analog volume controls, from the area identified for the home entertainment center.

A category 5E cable should be prewired from the home's primary PC to the MDF for programming and control of the PC based home controller if needed.

The electrical contractor should be instructed to insure that the line, neutral, & switch legs are available at all switch box locations and that only deep switch boxes be used for all planned smart switch and receptacle locations.

Specify that a minimum of 12 power receptacle outlets be installed at the MDF on its own power circuit ("breaker").  And 8 power receptacle at the entertainment centers. areas. It it also best to plan on battery backups for all sensitive equipment.

 

What is a Smart Home?

Smart Home is the term commonly used to define a residence that uses a Home Controller to integrate the residence's various home automation systems. The most popular Home Controllers are those that are connected to a Windows based PC. Integrating the home systems allows them to communicate with one another through the home controller, thereby enabling single button and voice control of the various home systems simultaneously.

For example, a scenario such as I'm Home could be triggered by pressing one button on a Key-chain Remote from your vehicle as you approach the driveway. The Home Controller receives the Key-chain Remote command triggering a scenario, pre-programmed and stored in the home controller. The celestial clock in the controller knows that it is 8 pm and past sunset, in your geographical location, therefore starting the scenario by sequentially turning on the lighting in the driveway, garage entry, walkway, hallway, and kitchen. It then disarms the security system, opens the garage door, unlocks the interior garage entry door, adjusts the thermostat(s) to a preset home position, and turns on the whole-house audio system. The home control processor is essentially the Hub of the home systems network.

The following is an overview of the system features that can be included in your Smart Home System.
