"PCS (Powerline Control Systems)
makes a specific X10 switching device that controls 4 different X10 addresses/circuits,
and mounts over a double- or triple-gang box. The device is model LM4L, controls up to
2000 watts total (max of 1000 watts on any one switch), intended for incandescents and
low-voltage lighting transformers, and works quite nicely"
I had a unique opportunity to select a lighting control system in my house - We had
been planning to build a house for about 5 years, and we got to the blueprint stage and I
knew that I wanted to have something beside standard wall switches - something that
controlled "the house", not just the "lights". I talked with Richard
Scholl at Worthington, and decided on using digital wall switches so that each single gang
box could provide control over a variety of devices in addition to lights. At that time,
the switch with the most potential was the Geffen Controller. But I knew there was trouble
when I went to Dallas to the home automation convention (about 2 years ago) and Geffen was
a no-show. Back to the drawing board with Richard. He sent me a Neltech keypad to examine,
and I decided that it was going to fit the need. Each Decora-style Neltech ( model 6D3+6)
I used has 6 buttons, is a model with small green LED lights marking each button as well
as three at the top (green/orange/red). When connected to a logical controller like my
StarGate, the LEDs can be controlled independently, and serve nicely to locate the buttons
in the dark. You can also use the LEDs to indicate off/on status of each/any device in the
house, armed/disarmed status of security systems, indicate whether garage door is open,
etc...
The Neltechs require most of the wires of two runs of Cat5 to be able to address all of
the functions, and connect directly to the digital connections of StarGate, which also
provides the power for the switch. I ordered the blank white buttoned Neltechs, and have
used a Brother labeler to print 3-letter labels to cover each button. I was reluctant to
have them engraved permanently until I was sure that the duty of each button wouldn't
change. The wires have plastic connectors for easy removal of the unit, and I know that
the little jewelry store kiosk at the local mall does engraving cheap, so I'll get that
job taken care of some day<G>. (Doesn't the list ever get shorter?) But going back
to the subject of lighting...having decided how to generate a signal, I needed to choose
the actuator for responding to the signal. Again with help and advice from Richard, I
decided that since the electrical wiring hadn't been pulled yet I could be a little
flexible. I had the electrician pull all of the switch legs for the lights into specific
locations such as the pantry (for living room/dining room/kitchen), a hall closet (for one
bathroom/bedroom), the utility room (for all outside lights), and the master bedroom
closet ( for master bed and bath). PCS (Powerline Control Systems) makes a specific X10
switching device that controls 4 different X10 addresses/circuits, and mounts over a
double- or triple-gang box. The device is model LM4L, controls up to 2000 watts total (max
of 1000 watts on any one switch), intended for incandescents and low-voltage lighting
transformers, and works quite nicely. They feature an easy-on that reduces burn-out, where
the light comes up from off to full bright in about half a second. This ramp-up is
noticeable but not negatively slow in an aesthetic sense, and I have not had to replace a
single light bulb served by these devices. Likewise they fade off rather than abrupt
action. The LM4 also can go from OFF to a percent level directly without first going to
bright. You can have them retain a preset level and then go back to the level when an
"on" is received. With StarGate I have found it is best to issue
"pre-set" commands rather than simple "on" commands, to insure I get
exactly the degree of brightness that I want for a given event. Finally, the LM4 responds
to All units Off, All lights on, and all lights off, and you can use advanced programming
of the unit to IGNORE one of these commands if you want to immunize a circuit from ALL
off, for example.
Of course, I have a Leviton whole-house surge supressor installed, as well as several X10
noise filters (one on an electric blanket for the SO, another on the Kenmore refrigerator
that turned out to be one bad noisy boy, X10 noise-pollution-wise), and a bridging
amplifier for the two phases of 110v. Don't automate home without these!
In all, I installed nine LM4s, controlling lights throughout the house. In the year since,
I have had two identical problems where one circuit of an LM4 stopped responding. One
locked into an on state, the other an off condition. In both cases PCS proved to be
completely responsive and repaired them and returned them to me in a timely manner, so I
have no complaints. One cannot reasonably expect indefinite infallibility in electronics
so I've learned to really value good customer service. I've installed a variety of other
X10 switches, for example a 4-way hallway circuit, and a couple of single-light wall
switches sprinkled around the house. These serve as a safety measure in the event that for
whatever reason my central system (StarGate) is down. I don't view home automation as
being infallible, and I have been known to make a mistake or two in programming
(<G>), so both my SO and daughter (and myself) feel better having a few good
old-fashioned paddle switches at hand. Lights can be controlled in our house using the
Neltechs (there are 8 in my house including one weatherproof model), using any phone (one
of StarGate's built-in virtues), using Leviton RF remote controls, and of course, the
paddle-switches. I bought a copy of both HAL2000 and HomeVoice in the hopes of adding
voice control to the system, but haven't gotten reliability to an acceptable level yet.
And after that, of course, we will be looking at the new user-interface product inspired
by the justice department's investigation of Microsoft - called Mindreader 1.0. Apparently
Bill Gates felt the need for this product during his meetings with congress, and with it
I'll be able to just THINK my lights on! Stay tuned for developments.
I was born in a log cabin in.....waitaminnit, wrong story. Okay, I'm from
south Texas, Uvalde to be exact. Mah forbears arrived in Natchitoches around 1843, and
have settled in various parts of Texas since then. I've lived in San Antone, Dallas, Round
Rock, and Austin since college, and find the hill country to be nearly perfect for my
lifestyle, so we are building a nice home in Lago Vista, 18 miles from downtown Austin.
Kind of like having yore cake, and french fries too.
I grew up in a real Rexall Drug Store in Uvalde, complete with soda fountain and
small-town benefits. Somehow I remained sane and gradjiated High School in 73'. I stayed
in Uvalde for a couple of years, attended a junior college, and got most of my pharmacy
pre-requisites out of the way. I also got a first degree brown belt in TaeKwanDo and
Kodokan Judo from sensei Lonnie Green, largely as self-defense from all of the republicans
that I matriculated with. (Enrollment was about 1000 people: 999 rednecks and me). Somehow
I was able to graduate from the University of Texas in1978 from College of Pharmacy with a
B.S. (seemed a fitting term, somehow). I spent my last year in San Antone at the UT HSC
where I received clinical training as a hospital pharmacist.
I have practiced pharmacy in independents, chain stores, apothecary, large hospitals
(>600 beds) and small hospitals (<100 beds). Also directed the services for a small
hospital for 4 years, and learned to design databases and build/program computers in my
spare time. Co-authored a dynamic comprehensive pharmacy management system called Rx-Link
, using DataEase for DOS, a 4th-generation relational RAD tool (See Periwinkle's page for
DataEase info). RxLink is perhaps the largest PC-based computer tool for running a
hospital pharmacy, in terms of reports and features.
I currently provide custom programming solutions and training in PC operations. I've
logged more than 1.5 million miles with American Airlines, am a life-time gold member with
platinum membership in AA, Marriott Marquis Platinum, gold standing with Hurts, er,
Hertz., traveling to hospitals around the YewEssHay and Canada. I've personally trained
pharmacists in more than 100 hospitals and analyzed pharmacy practices in those hospitals
in order to customize their softwares. I am a technofreak, believing that if it is new and
technical, it must be better, and if it doesn't turn out that way then it was incorrectly
documented and improperly implemented. Two books I think yew should read: High Road(Ben
Bova) and Diamond Age (Neal Stephenson).
